在gridview下拉列表中选择更改事件 [英] in gridview dropdown selected change event

问题描述

尊敬的先生，

我有一个网格视图，其中一列包括带有Dropdown
的itemtemplate

我在列中绑定了第一个下拉列表

Dear sir,

i have a grid view in which one column consist of itemtemplate with Dropdown

i binded first dropdown in a column

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {

           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               if (e.Row.RowIndex == 0)
               {
                   DataTable dt = new DataTable();
                   string str1 = e.Row.Cells[4].Text.ToString();
                   string str2 = "0";
                   dt = BLAutoComplete.GetFirstDdl(str1, str2);
                   DropDownList DDL = (DropDownList)e.Row.FindControl("ddl1");
                   DDL.DataSource = dt;
                   DDL.DataTextField = "CURRENT_NAME";
                   DDL.DataValueField = "CURRENT_ID";
                   DDL.DataBind();
                   DDL.Items.Insert(0, "--Select--");

               }
           }
       }

我需要第一行下拉selectedindex更改我需要绑定同一列第二行下拉

i need first row dropdown selectedindex change i need to bind same column second row dropdown

推荐答案

如果删除以下条件怎么办?

What if you remove the following condition?

if (e.Row.RowIndex == 0)

为在行数据绑定事件和dropdownselectionchanged事件中更改的下拉选择创建一个偶数处理程序

Create an even handler for dropdown selection changed in row databound event and in dropdownselectionchanged event

foreach (GridViewRow gr in GridView1.Rows)
        {
            DropDownList DDL = (DropDownList)gr.FindControl("DropDownList2");
            if (gr.RowIndex == 1)
            {
            // code to populate dropdownlist    
            }
        }
