How to set SelectedValue of DropDownList in GridView EditTemplate

Question

I am trying to do this as asked earlier. The only difference that I found is additional List item that was included in above code.

I tried to use AppendDataBou

The use of the GridView_DataBound event handler solves the problem.

In your case you will need to add a HiddenField to store the PK_DepartmentId value:

  
    
      
        
        
        
        
        
      
      
        
        
      
    
    
  


protected void gvExample_DataBound(object sender, EventArgs e)
{
  foreach (GridViewRow gvRow in gvExample.Rows)
  {
    DropDownList ddlDepartment = gvRow.FindControl("ddlDepartment_Edit") as DropDownList;
    HiddenField hfDepartmentId = gvRow.FindControl("hfDepartmentId") as HiddenField;

    if (ddlDepartment != null && hfDepartmentId != null)
    {
      ddlDepartment.SelectedValue = hfDepartmentId.Value;
    }
  }
}
