Asp.Net Gridivew PageIndexchanging problem

Before paging you need to store the old values, after paging done rebind the new data.

Or, use UpdatePanel might works.

Or, do not allow user to do paging during edit mode.

I dont think your pageindexchanging function is wrong. Try during debug mode, find between add new button click event  and databing, check if your grid data is null or not.

Hi Suthish,

I have used it... but then also its not working..

How you binding the records, on Page Load? If yes then use if(!IsPostBack) condition.
 

Hi Vijay,

I had tried this but it clears the gridview anyway..

Thanks,
Vijay

Hi Manish,
 public void children()
    {
      
        int num = 0;
        dt = new DataTable();

        dt.Columns.Add("SR_NO", typeof(string));
        dt.Columns.Add("EMPLOYEE_CODE", typeof(string));
        dt.Columns.Add("EMPLOYEE_NAME", typeof(string));
        dt.Columns.Add("CHILD_NAME", typeof(string));
        dt.Columns.Add("CHILD_AGE", typeof(string));
        foreach (GridViewRow row in grvChildrenDetails.Rows)
        {
            DataRow dr;
            dr = dt.NewRow();

            dr["SR_NO"] = ((Label)row.FindControl("lblsr_no")).Text;
            dr["CHILD_NAME"] = ((TextBox)row.FindControl("txtchildname")).Text;
            dr["CHILD_AGE"] = ((TextBox)row.FindControl("txtchildage")).Text;
            num =Convert.ToInt32(dr["SR_NO"]);
            dt.Rows.Add(dr);
        }


       // dt = (DataTable)grvChildrenDetails.DataSource;

        if (num > 4)
        {
        }
        else
        {
            DataRow dr1 = dt.NewRow();

            dt.Rows.Add(dr1);
          
            //DataView dv = dt.DefaultView;
            grvChildrenDetails.DataSource = dt;
            grvChildrenDetails.DataBind();
          
        }

        
    }
this function i call on button click in footer to add new row

and on page index changing..
protected void grvChildrenDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {

Vijay,

Can you post your code here. It would be fine to solve your problem.

Hi friends,

@Manish i have binded that function but still it is not getting done and
@Jitendra not solved yet, if you know please tell me..

Thanks,
Vijay

Hi,
Is your problem solved? send me the code if not.

Hi Vijay,

I think you are not binding the gridview in PageIndexchanging event.
try this

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    BindGrid();
}
