Im unable to get the quantity as per selection in SelectedIndexChanged

What I have tried:

C#

protected void gvAgent_SelectedIndexChanged(object sender, EventArgs e)
    {
        foreach (GridViewRow row in gvAgent.Rows)
        {
            if (row.RowIndex == gvAgent.SelectedIndex)
            {
                row.BackColor = ColorTranslator.FromHtml("#A1DCF2");
                row.ToolTip = string.Empty;
            }
            else
            {
                row.BackColor = ColorTranslator.FromHtml("#FFFFFF");
                row.ToolTip = "Click to select this row.";
            }
        }
  GridViewRow gvrow = gvAgent.SelectedRow;

        string Quantity = "";
        int SpareID = Convert.ToInt32(this.gvAgent.SelectedDataKey.Value.ToString());

        lblCustomerID.Text = "";
        lblSpareID.Text = gvrow.Cells[0].Text;
        //lblSpareID.Text = SpareID.ToString();
        DataTable dtData = objSpare.GetSpareValues((Convert.ToInt32(SpareID.ToString())), Quantity);
        txtPartDetails.Text = gvrow.Cells[3].Text;
        txtQuantity.Text = gvrow.Cells[6].Text;
        txtPrice.Text = gvrow.Cells[8].Text;

        txtPartDetails2.Text = gvrow.Cells[3].Text;
        txtQuantity2.Text = gvrow.Cells[6].Text;
        txtPrice2.Text = gvrow.Cells[8].Text;

Shahbaz435 18-Nov-17 8:51am

Karthik_Mahalingam 18-Nov-17 8:59am

Shahbaz435 18-Nov-17 9:03am

yes it is showing me the data in textbox but i want the showing the data in textbox as per my selection on multiple times but its is clickable at once

Karthik_Mahalingam 18-Nov-17 9:10am

clickable at once?
meaning?
show the page load code

Shahbaz435 18-Nov-17 9:14am

yes it is clickable only once 2nd time it wont be clicked

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.QueryString["CID"] != null)
{
//FillData();
}

lblMsg.Text = "";
FillGrid();
}
}

Karthik_Mahalingam 18-Nov-17 9:15am

does the postback happens on second time?

Shahbaz435 18-Nov-17 9:15am

no

Karthik_Mahalingam 18-Nov-17 9:19am

remove this code and try
foreach (GridViewRow row in gvAgent.Rows)
{
if (row.RowIndex == gvAgent.SelectedIndex)
{
row.BackColor = ColorTranslator.FromHtml("#A1DCF2");
row.ToolTip = string.Empty;
}
else
{
row.BackColor = ColorTranslator.FromHtml("#FFFFFF");
row.ToolTip = "Click to select this row.";
}
}

Shahbaz435 18-Nov-17 9:20am

this for click event in gridview

Karthik_Mahalingam 18-Nov-17 9:22am

you should add this code in rowbound event, this will be unnecessary burden for the grid to render, since you are looping everytime

Shahbaz435 18-Nov-17 9:21am

nothing can happen after removing this code

Karthik_Mahalingam 18-Nov-17 9:23am

are you using any javascript ?

Shahbaz435 18-Nov-17 9:25am

noooooooooo

Karthik_Mahalingam 18-Nov-17 9:26am

post your related gridview code, let me examine and get you back

Laxmidhar tatwa technologies 20-Nov-17 23:38pm

Laxmidhar tatwa technologies 21-Nov-17 1:42am
