Passing the selected gridview row to a new page for edit

Hey Friend ,

Post your Code of Page 1

and What you have Coded in Page 2 Here

I m not getting you Explain a lil bit what you want to achieve as Final Result .

Happy Coding :)

if you have added Bool Value in session at page 1 like

Session["Discontinued"] = checkBox1.Checked ;

then you can Check it at receiving time in page 2

like below

bool ReceivedValue = Convert.ToBoolean(Session["Discontinued"].ToString());

if ( ReceivedValue == false )
{
// Do Somthing
}

Hi Here is What you need now you Dont have to Select the Row too. :)

        protected void GridView1_RowEditing1(object sender, GridViewEditEventArgs e)
        {
            int index = e.NewEditIndex;
            Session["Username"] = GridView1.Rows[index].Cells[0].Text;
            Session["Password"] = GridView1.Rows[index].Cells[1].Text;

        }

Hi ,

Make Sure You have Selected the Row First Then Press Edit and Grid Must Have Some Data like Below Image




Error Says that GridView's Cell[0] contain Null Data  ( having No string Value )

You can Check the Grid's Content before Sending it to Session

if your Cell[0] is template field Then let me know other Wise Code is Correct

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        if (GridView1.SelectedRow.Cells[0].Text != null && GridView1.SelectedRow.Cells[1].Text != null)
        {
            Session["Username"] = GridView1.SelectedRow.Cells[0].Text;
            Session["Password"] = GridView1.SelectedRow.Cells[1].Text;
        }
    }

Happy Coding :)

Hi ,

you can do this By Session use Following Code

In Page 1 Write Code as below for example if We are passing two columned Row(Username ,Password)

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        Session["Username"] = GridView1.SelectedRow.Cells[0].Text;
        Session["Password"] = GridView1.SelectedRow.Cells[1].Text;
    }

In Page 2 Write Code Below to Retrieve Data From Session that We have Stored in Session

protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Text = Session["Username"].ToString();
        Label2.Text = Session["Password"].ToString();
    }

Happy Coding :)

First we need to setup our grid in our main page called RedirectMyGridView.aspx: Next we need to create our datasource and bind it on our page_load event: using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; public partial class RedirectMyGridView : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { this.BuildGridViewItems(); } } private void BuildGridViewItems() { DataTable dt = new DataTable(); DataColumn siteIdColumn = new DataColumn("SiteId"); DataColumn siteNameColumn = new DataColumn("SiteName"); dt.Columns.Add(siteIdColumn); dt.Columns.Add(siteNameColumn); DataRow dr1 = dt.NewRow(); dr1[siteIdColumn] = "1"; dr1[siteNameColumn] = "Google"; dt.Rows.Add(dr1); DataRow dr2 = dt.NewRow(); dr2[siteIdColumn] = "2"; dr2[siteNameColumn] = "Yahoo"; dt.Rows.Add(dr2); DataRow dr3 = dt.NewRow(); dr3[siteIdColumn] = "3"; dr3[siteNameColumn] = "MSN"; dt.Rows.Add(dr3); DataRow dr4 = dt.NewRow(); dr4[siteIdColumn] = "4"; dr4[siteNameColumn] = "DevPinoy"; dt.Rows.Add(dr4); urlGrid.DataSource = dt; urlGrid.DataBind(); } } After that we need to setup our accepting page called RedirectToUrl.aspx: using System; public partial class RedirectToUrl : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Request.QueryString["SiteId"] != null) { string redirectionUrl = ""; try { //get the value of the site id; int siteId = int.Parse(Request.QueryString["SiteId"].ToString()); //check if siteid is inside the defined bounds. do nothing if it fails. if (siteId > 4 || siteId < 1) { return; } //chck and compare if (siteId == 1) { redirectionUrl = "http://www.google.com"; } else if (siteId == 2) { redirectionUrl = "http://www.yahoo.com"; } else if (siteId == 3) { redirectionUrl = "http://www.msn.com"; } else if (siteId == 4) { redirectionUrl = "http://www.devpinoy.com"; } //redirect to the selected location Response.Redirect(redirectionUrl); } catch { //throw our error. throw new Exception("cannot parse siteid... value must be out of range!"); } } } }

Create A Class Named PassDataClass like below

 

using System; using System.Collections.Generic; using System.Linq; using System.Web; public class DataPassClass { public static string Name ; public static string Age; }

Now in Page 1 Write Code In Button1 to pass the Data to that class and We can retrieve content passed to class from page 2

Page 1 Code is Below

protected void Button1_Click(object sender, EventArgs e) { DataPassClass.Name = GridView1.SelectedRow.Cells[0].Text; DataPassClass.Age = GridView1.SelectedRow.Cells[1].Text; Response.Redirect("~/PassData.aspx"); }

And in Page 2 Write Code Like Below

protected void Page_Load(object sender, EventArgs e) { Label1.Text = DataPassClass.Name; Label2.Text = DataPassClass.Age; }

You can also Do this Task Without Creating Class File With Session But If you Create Class you can Manage the Code Efficiently.
