在GridView中添加新行时绑定下拉列表

Question

我在gridview中有一个下拉列表和一些文本框，并且从数据库值中绑定了DDL，我必须添加具有相同DDL和文本框的新行，但是当创建新行时如何绑定DDL？

Answer 1

You can add the new row in GridView Footer. During RowDataBound event you can find the DDL and Bind the data,

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Footer)
    {
        DropDownList ddlName= (DropDownList)e.Row.FindControl("dlstName");
        // You can bind data to ddlName
    }
}
