Vulpes · Answer

In Calendar1_SelectionChanged, try this code: DateTime dt = Calendar1.SelectedDate + DateTime.Now.TimeOfDay; txtchin.Text = dt.ToString("yyyyMMdd HH:mm:ss");

Vulpes · Answer

Sorry for the delay in responding but I've been away for a couple of days. Well, off the top of my head, the code to do all that will be along the following lines. However, you'll need to make sure that the data types in the database correspond to what I've assumed and also need to add some try/catch statements in case there are exceptions. protected void BtnInsert_Click(object sender, EventArgs e) { string conStr = "whatever"; SqlConnection con = new SqlConnection(conStr); SqlCommand cmd = new SqlCommand(); cmd.Connection = con; cmd.CommandText = "INSERT INTO sometable([textcol], [dropdowncol], [calendarcol]) VALUES(@text, @dropdown, @calendar)"; cmd.Parameters.Add("@text", SqlDbType.VarChar).Value = TextBox1.Text; cmd.Parameters.Add("@dropdown, SqlDbType.VarChar").Value = DropDownList.SelectedItem.Text; cmd.Parameters.Add("@calendar", SqlDbType.Date).Value = Calendar1.SelectedDate; cmd.ExecuteNonQuery(); con.Close(); } protected void BtnUpdate_Click(object sender, EventArgs e) { string conStr = "whatever"; SqlConnection con = new SqlConnection(conStr); SqlCommand cmd = new SqlCommand(); cmd.Connection = con; // it's assumed that [textcol] is a primary key or otherwise unique column cmd.CommandText = "UPDATE sometable SET [textcol] = @text, [dropdowncol] = @dropdown, [calendarcol] = @calendar WHERE [textcol] = @prevtext"; cmd.Parameters.Add("@prevtext, SqlDbType.VarChar).Value = "whatever"; cmd.Parameters.Add("@text", SqlDbType.VarChar).Value = TextBox1.Text; cmd.Parameters.Add("@dropdown, SqlDbType.VarChar").Value = DropDownList.SelectedItem.Text; cmd.Parameters.Add("@calendar", SqlDbType.Date).Value = Calendar1.SelectedDate; cmd.ExecuteNonQuery(); con.Close(); } protected void BtnDelete_Click(object sender, EventArgs e) { string conStr = "whatever"; SqlConnection con = new SqlConnection(conStr); SqlCommand cmd = new SqlCommand(); cmd.Connection = con; // it's assumed that [textcol] is a primary key or otherwise unique column cmd.CommandText = "DELETE FROM sometable WHERE [textcol] = @text"; cmd.Parameters.Add("@text", SqlDbType.VarChar).Value = TextBox1.Text; cmd.ExecuteNonQuery(); con.Close(); } If you're reloading the page without saving the current Challen number first, then the numbering will start again from the last saved value in the database.

Vulpes · Answer

The code should be put in the Page_Load handler within the 'if' statement so that the last number only loads once from the database, not on each post-back.

Vulpes · Answer

Well it will, of course, depend on which database you're using but, for SQL Server, the code will be something like this ( EDITED ): string conStr = "whatever"; SqlConnection con = new SqlConnection(conStr); SqlCommand cmd = new SqlCommand(); cmd.Connection = con; cmd.CommandText = "SELECT TOP 1 challen FROM sometable ORDER BY challen DESC"; con.Open(); SqlDataReader reader = cmd.ExecuteReader(); string challen = "AS000"; if (reader.HasRows) { reader.Read()) challen = reader["challen"].ToString(); } reader.Close(); con.Close(); Label1.Text = challen; Session["Challen"] = challen;

Vulpes · Answer

Something like this perhaps: public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { string challen = "AS001"; // or load last one saved from database Label1.Text = challen; Session["Challen"] = challen; } } protected void Button1_Click(object sender, EventArgs e) { string challen = Session["Challen"].ToString(); int number = int.Parse(challen.Substring(2)) + 1; challen = "AS" + number.ToString("D3"); Label1.Text = challen; Session["Challen"] = challen; } }

Vulpes · Answer

If you've made the date column a primary key, or given it the unique constraint, in the database, then you won't be able to save two records with the same date in the database. However, if you use a full date/time including seconds (and possibly milliseconds), then you should be OK as the times when individual records are saved should then be unique.

Amol Sonavane · Answer

Hello Sir, when i select a one date for record and save it..after that i choose same date for another record..at that time selected date is invisible or selected... what the reason is this any solution.. means i want to save two records in same date but after first record inserted this date is invisible or selected i cant select that date....

Hi sir i have created demo application for date and send you... has same problem for timing...please have a look

Vulpes · Answer

Can you post the code then. I'll see if I can figure out what the problem is.

Amol Sonavane · Answer

yes sir.... i have taken a database DateTime in database..

Vulpes · Answer

Have you added the time component in the way that I suggested? Also is the column type in the database one that supports both date and time - in other words is it something other than the 'date' type which only supports dates?

Amol Sonavane · Answer

sorry sir its not working it also show 12.00

Vulpes · Answer

ToLongDateString() will give you something like 28 August 2014. If you want both the date and time and want to be reasonably sure the datebase will accept it, I'd use: ToString ("yyyyMMdd HH:mm:ss").

Amol Sonavane · Answer

I write ToLongDate instead of Tostring for getting day and date but got a error when inserting.. Error-Conversion failed when converting date and/or time from character string.

Amol Sonavane · Answer

k sir...can we print the day by using this...

Vulpes · Answer

AFAIK, it's not possible to set a time using the Calendar control. If you want to graft the current time onto whatever the selected date is, you could do this: DateTime dt = Calendar1.SelectedDate + DateTime.Now.TimeOfDay; As I said earlier I don't use Crystal Reports. I'd look for a suitable article of which there are plenty on this site alone: http://www.c-sharpcorner.com/tags/1/Crystal-Reports/

Amol Sonavane · Answer

Hello Sir, How to create crystal report?

Amol Sonavane · Answer

hello sir... by using calender control is it possible or not?

Vulpes · Answer

Well, if you're obtaining the date from the Calendar control it will show as 12.00 am because the control can only deal with dates and the time component will always therefore be zero hours. If you want to insert the current date and time , I'd use DateTime.Now rather than Calendar1.SelectedDate. Sorry, I don't use Crystal Reports. I'd either search for an article on it or ask the question again in a new thread.

Amol Sonavane · Answer

Thanks Sir I will check...

Vulpes · Answer

Well, I'm not surprised it's not working because the code to get the latest Challen number from the database when the page loads and to store the incremented number in Session state when the ImageButton is clicked is all commented out! Anyway, I've tried to reconstruct it below. Unfortunately, I can't test this as I don't have any ASP.NET stuff on the machine I'm using just now so there may be bugs. Ideally, the SqlConnection object should be stored globally but I've stored it in Session state for now. I wouldn't bother storing the SqlCommand and SqlDataReader objects - I'd just create them as needed. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; using System.Configuration; namespace VISInventorySystem { public partial class InwardForm : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { grdInward.Visible = false; Calendar2.Visible = false; SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString); Session["Connection"] = con; // store in Session state for now SqlCommand cmd = new SqlCommand(); cmd.Connection = con; cmd.CommandText = "SELECT TOP 1 InChallenNo FROM tbInward ORDER BY InChallenNo DESC"; con.Open(); SqlDataReader reader = cmd.ExecuteReader(); string challen = "AS000"; if (reader.HasRows) { reader.Read(); challen = reader["InChallenNo"].ToString(); } reader.Close(); con.Close(); lblInChallen.Text = challen; Session["Challen"] = challen; } } protected void Calendar2_SelectionChanged(object sender, EventArgs e) { txtReceiveDate.Text= Calendar2.SelectedDate.ToString("d"); Calendar2.Visible = false; } protected void Calendar2_DayRender(object sender, DayRenderEventArgs e) { if (e.Day.IsOtherMonth) { e.Day.IsSelectable = false; } } protected void ImageButton2_Click(object sender, ImageClickEventArgs e) { if (Calendar2.Visible) { Calendar2.Visible = false; } else { Calendar2.Visible = true; } // don't know whether this code is dependent on visibility of calendar on not? string challen = Session["Challen"].ToString(); int number = int.Parse(challen.Substring(2)) + 1; challen = "AS" + number.ToString("D3"); lblInChallen.Text = challen; Session["Challen"] = challen; } protected void btnInSave_Click(object sender, EventArgs e) { SqlConnection con = (SqlConnection)Session["Connection"]; con.Open(); string query = "Insert into tbInward(InChallenNo,InProdCategory,InProdDetails,InSerialNo,InReceivedlocation,InReceivedDate,Comments)values('"+lblInChallen.Text+"','"+ddlInProdCategory.SelectedValue+"','"+txtInPDetails.Text+"','"+txtInSerialNumber.Text+"','"+ddlInLocation.SelectedValue+"','"+txtReceiveDate.Text+"','"+txtInComments.Text+"')"; SqlCommand cmd = new SqlCommand(query,con); cmd.CommandType = System.Data.CommandType.Text; cmd.ExecuteNonQuery(); Response.Write("Record has been inserted"); con.Close(); ddlInProdCategory.SelectedValue = ""; txtInPDetails.Text = ""; txtInSerialNumber.Text = ""; ddlInLocation.SelectedValue = ""; txtInComments.Text = ""; txtReceiveDate.Text = ""; } protected void btnNewForm_Click(object sender, EventArgs e) { txtInComments.Text = ""; txtInPDetails.Text = ""; txtInSerialNumber.Text=""; txtReceiveDate.Text=""; ddlInLocation.Text=""; ddlInProdCategory.Text=""; } protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { } protected void btnInView_Click(object sender, EventArgs e) { grdInward.Visible = true; } protected void btnInUpdate_Click(object sender, EventArgs e) { SqlConnection con = (SqlConnection)Session["Connection"]; con.Open(); string query1 = "update tbInward set InChallenNo='"+lblInChallen.Text+"',InProdCategory='"+ddlInProdCategory.SelectedValue+"',InProdDetails='"+txtInPDetails.Text+"',InSerialNo='"+txtInSerialNumber.Text+"',InReceivedlocation='"+ddlInLocation.SelectedValue+"',InReceivedDate='"+txtReceiveDate.Text+"',Comments='"+txtInComments.Text+"' where (InSerialNo='"+txtInSerialNumber.Text+"')"; SqlCommand cmd = new SqlCommand(query1, con); cmd.ExecuteNonQuery(); con.Close(); ddlInProdCategory.SelectedValue = ""; txtInPDetails.Text = ""; txtInSerialNumber.Text = ""; ddlInLocation.SelectedValue = ""; txtInComments.Text = ""; txtReceiveDate.Text = ""; } protected void btnSearch_Click(object sender, EventArgs e) { SqlConnection con = (SqlConnection)Session["Connection"]; con.Open(); string query = "Select * from tbInward where InSerialNo='" + txtInSerialNumber.Text + "'"; //string query1 = "Select * FROM tbRMC WHERE Cno='" + txtcno.Text + "'"; SqlCommand cmd2 = new SqlCommand(query, con); //SqlDataReader reader; SqlDataReader rd = cmd2.ExecuteReader(); //if (reader.IsClosed == false && reader.HasRows) if(rd.IsClosed==false && rd.HasRows) { if (rd.Read()) { lblInChallen.Text = rd["InChallenNo"].ToString(); ddlInProdCategory.Text = rd["InProdCategory"].ToString(); txtInPDetails.Text = rd["InProdDetails"].ToString(); //txtInSerialNumber.Text = rd["InSerialNo"].ToString(); ddlInLocation.Text = rd["InReceivedlocation"].ToString(); txtReceiveDate.Text = rd["InreceivedDate"].ToString(); txtInComments.Text = rd["Comments"].ToString(); //lbl_Cno.Text = reader["Cno"].ToString(); //txtTo.Text = reader["CTo"].ToString(); //txtContactNo.Text = reader["ContactNo"].ToString(); //txtBatchNo.Text = reader["BatchNo"].ToString(); //txtLOS.Text = reader["LOS"].ToString(); //txtDate.Text = reader["Date"].ToString(); //lblRQ.Text = reader["RQ"].ToString(); //txtWAT.Text = reader["WAT"].ToString(); //txtVIOTAS.Text = reader["VIATAS"].ToString(); //txtTOCA.Text = reader["TOCA"].ToString(); //txtTMN.Text = reader["TMN"].ToString(); //txtSTA.Text = reader["STA"].ToString(); //txtSQ.Text = reader["SQ"].ToString(); //txtOQ.Text = reader["OQ"].ToString(); } } else { Response.Write("No Record Found"); } rd.Close(); con.Close(); ddlInProdCategory.SelectedValue = ""; txtInPDetails.Text = ""; txtInSerialNumber.Text = ""; ddlInLocation.SelectedValue = ""; txtInComments.Text = ""; txtReceiveDate.Text = ""; } protected void btnInDelete_Click(object sender, EventArgs e) { SqlConnection con = (SqlConnection)Session["Connection"]; con.Open(); string query1 = "delete from tbInward where InProdCategory='"+ddlInProdCategory.SelectedValue+"'"; SqlCommand cmd = new SqlCommand(query1, con); cmd.ExecuteNonQuery(); con.Close(); ddlInProdCategory.SelectedValue = ""; txtInPDetails.Text = ""; txtInSerialNumber.Text = ""; ddlInLocation.SelectedValue = ""; txtInComments.Text = ""; txtReceiveDate.Text = ""; } } }

Vulpes · Answer

I didn't follow how your imagebutton and calendar controls are associated with each other. If you click on the imagebutton, then I can't think of any obvious reason why the code wouldn't work the same as for an 'ordinary' button. However, if you click on the calendar control, then there isn't a Click event as such. However, there is a SelectionChanged event. Can you clarify the position here.
