private void adddescription()
{
int rowIndex = 0;

          if (ViewState\["CurrentTable"\] != null)
          {
              //DataTable dtCurrentTable = (DataTable)ViewState\["CurrentTable"\];
              dtDesc = (DataTable)ViewState\["CurrentTable"\];
              DataRow drCurrentRow = dtDesc.NewRow();
              if (dtDesc.Rows.Count > 0)
              {
                  for (int i = 1; i <= dtDesc.Rows.Count; i++)
                  {
                      //extract the TextBox values
                      TextBox box1 = (TextBox)Rptdescription.Items\[rowIndex\].FindControl("TextName");
                      TextBox box2 = (TextBox)Rptdescription.Items\[rowIndex\].FindControl("TextDate");
                      TextBox box3 = (TextBox)Rptdescription.Items\[rowIndex\].FindControl("TextDescript");
                      drCurrentRow = dtDesc.NewRow();
                      drCurrentRow\["RowNumber"\] = i ;
                      ViewState\["RowNumber"\] = drCurrentRow\["RowNumber"\];
                      Label1.Text = ViewState\["RowNumber"\].ToString();
                      dtDesc.Rows\[i - 1\]\["DescriptionName"\] = box1.Text;
                      dtDesc.Rows\[i - 1\]\["Date"\] = box2.Text;
                      dtDesc.Rows\[i - 1\]\["Description"\] = box3.Text;
                      rowIndex++;
                  }
                  dtDesc.Rows.Add(drCurrentRow);
                //  ViewState\["CurrentTable"\] = dtDesc;
              }
              else
              {
                  dtDesc = (DataTable)ViewState\["CurrentTable"\];
                  // dtDesc = (DataTable)ViewState\["CurrentTable"\];
                  DataRow descRow = dtDesc.NewRow();
                  //  descRow\["ProjectID"\] = dtDesc.Rows.Count + 1;
                  descRow\["DescriptionName"\] = "";
                  descRow\["Date"\] = "";
                  descRow\["Description"\] = "";
                  dtDesc.Rows.Add(descRow);
                //  ViewState\["CurrentTable"\] = dtDesc;
              }
          }
          Bindrepeater();
}

Okay.Delete button is in the repater.right?then in the delete button click event you'll get the item index and using that item index delete that object from the viewstate and rebind repeater.is that makes sense?

im losing the values in textboxs on postback.... i cant check which row im deleting correctly as the values go on postback...

int iddelete;
iddelete = ToInt(e.CommandArgument.ToString());
if (iddelete!=0)
{
//code....
}
else
{

        int count = e.Item.ItemIndex;
        
       // count = Convert.ToInt32(ViewState\["RowNumber"\]);
       //DataTable dtdelete = (DataTable)ViewState\["CurrentTable"\];
      //  count = dtdelete.Rows.Count - 1;
        dtdelete.Rows\[count\].Delete();
        dtdelete.AcceptChanges();
        Rptdescription.DataSource = dtdelete;
        Rptdescription.DataBind();

       }

Which values you are loosing?ItemIndex is enough to delete it from ViewState?Is this code working?whats the difficulty you are facing in the above code? If you are saying about entered values in textboxes, then save that values to the persisting object before rebinding the repeater.

the last row is deleting if i click on delete of any row... what may be problem

[Arindam Tewary]

You might have 'hard coded' index of last row. Please check that. This could be the case. :laugh:

Thanks, Arindam D Tewary
