I am using a gridview which is showing data using datatable.And i am using ItemTemplate to show data as i have made autogenratecolumn False.The problem is when i do edit then i am binding data to textboxes using eval but when it comes to dropdownlist i am using datatable and fetch data from database and using findcontrol property i do bind data to dropdown.But i am not able to bind the selectedvalue to dropdown which was already selected to that column.

Like someone already select the value of city "Delhi".and when i do it edit dropdown should show the "Delhi" as selected in edit mode.

Hi,

You need to set the DataKeyNames as the value of the DropDownList control. Then in the GridView GridView1_RowDataBound event, use the below code.

if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList cmbType = (DropDownList)e.Row.FindControl("cmbType");

if (cmbType != null)
{
cmbType.DataSource = customer.FetchCustomerType();
cmbType.DataBind();
cmbType.SelectedValue = GridView1.DataKeys[e.Row.RowIndex].Values[1].ToString();
}
}
