问题描述

如何在页面加载时从asp.net中的另一个表将数据源设置为gridview的dropdownlist中的c#

how to set datasource to dropdownlist in gridview at page load from another table in asp.net c#

推荐答案

如果页脚中存在下拉菜单，则更好RowDataBound，

If you have dropdown in footer means better to go for RowDataBound,

protected void gvBindDropDown_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Footer)
        {
            DropDownList dropDownList = e.Row.FindControl("dropDownListID") as DropDownList;
            dropDownList.DataSource = dtDropDownData;  //Datatable 
            dropDownList.DataTextField = "Description";
            dropDownList.DataValueField = "Value";
            dropDownList.DataBind();
            dropDownList.Items.Insert(0, new ListItem("-Select-", "0"));
        }
    }

如果存在，则行表示使用

if it is there Row means use

if (e.Row.RowType == DataControlRowType.DataRow)
{
    //Bind drop down..
}
