gridview 模板列事件

Question

   gridview 在编辑状态下。模板列中的dropdownlist 如何触发事件啊？ 

Answer 1

//先要找到触发事件的行  GridViewRow editRow = (GridViewRow)((Control)sender).Parent.Parent;//然后找到控件        DropDownList ddl = (DropDownList)(editRow.FindControl("dropdownListName"));
       TextBox txt = (TextBox)(editRow.FindControl("textBoxName"));//再赋值：
        txt.Text = ddl.SelectedItem.Text;把DropDownList的AutoPostBack属性设置为true; 
然后在SelectedIndexChange()事件中写.

Answer 2

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)  
{  
if (e.Row.RowType == DataControlRowType.DataRow)  
{  
if (e.Row.FindControl("DropDownList1") != null)  
{  
DropDownList ddl =e.Row.FindControl("DropDownList1") as DropDownList;  
ddl.DataSource = ds;  
ddl.DataBind();   
}  
}  
}  
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)  
{  
  GridViewRow gvr = (sender as DropDownList).NamingContainer as GridViewRow;  
  if(gvr != null)  
  {  
  DropDownList ddl = gvr.FindControl("DropDownList1") as DropDownList;  
  if(ddl != null)  
  {  
    
  }  
  }  
}
