如何在文本框中根据gridview selectedindexchanged获得1个数量 [英] How do I get 1 quantity as per gridview selectedindexchanged in textbox

问题描述

我无法根据SelectedIndexChanged中的选择获得数量



我尝试了什么：

Im unable to get the quantity as per selection in SelectedIndexChanged

What I have tried:

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;
