ADDing Dropdownlist in gridview [Resolved]

Hi Harsh,

Use hiddenfield in your gridview & bind the value of customerid into hiddenfield, then you have to get the hidden field's value for the corresponding rowid that also get in the previous posts.

in your selected index changed event for dropdown enter below code to access the customerid on that row,

protected void ddlRoles_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddl_Roles = (DropDownList)sender;
GridViewRow row = (GridViewRow)((Control)sender).Parent.Parent;

// Change the cell no to your current position of a hiddenfield
int customerId = ((HiddenField)row.Cells[2].FindControl("hdnCustomerId")).Value

}

Best Ragards,

Bind your grid with the Customerid and hide it. in tell your gridview that the primary key is Customerid by adding this property in the defination of the gridview

DataKeyNames="Customerid "

onselectedindexchanged of the dropdown in the grid and on the server side if you want to get the id of that row, do this

 

        //If we are using our gridview1 do the Following 

            // parse through the grdview rows

            foreach (GridViewRow row in grdViewTreeRules.Rows)

            {

                String Customerid = Convert.ToString(grdViewTreeRules.DataKeys[row.RowIndex].Value);



               DropDownList ddl = (DropDownList)row.Cells[2].FindControl("drplstparent"); //the Index there is where the dropdown is, this is when you want to get the value of a     dropdown



                String Dropdownvalue = ddl.SelectedValue;

}
