无法为gridView中的下拉列表生成事件 [英] Unable to Genrate an event for DropDown list in gridView

问题描述

你好
我无法在RowUpdate()或RowCommand()中的edittemplate中生成下拉列表的selectedItem事件

Hello
I am not able to genrate selectedItem Event for Dropdown list in edittemplate in RowUpdate() nor in RowCommand()

protected void GridViewDepartment_RowUpdating(object sender, GridViewUpdateEventArgs e)  
{
   getConnection = connection.SetConnection();
   GridView GridViewDepartment = (GridView)sender;
   GridViewDepartment.EditIndex = e.RowIndex;
   GridViewDepartment.DataSource = departmentTable;
   GridViewDepartment.DataBind();
   int DepartmentID = (int)GridViewDepartment.DataKeys[e.RowIndex].Value;
   DropDownList ddlManager = ((DropDownList)GridViewDepartment.Rows[e.RowIndex].FindControl("ddlDepartManager"));
 string AssignNewManagr = ddlManager.SelectedItem.Text.ToString(); // this selecting only "select" 0th item only even on changing index
string AssignNewActive = ((DropDownList)GridViewDepartment.Rows[e.RowIndex].FindControl("DropDownListActive")).SelectedItem.ToString();
                    string SPUPDateDepartment = "SPModifyDepartment";
 SqlCommand UPDateCommnad = new SqlCommand(SPUPDateDepartment, getConnection);
 UPDateCommnad.CommandType = CommandType.StoredProcedure;
 UPDateCommnad.Parameters.AddWithValue("@DepartmentId", DepartmentID);
 UPDateCommnad.Parameters.AddWithValue("@DepartmentManager", AssignNewManagr);
 UPDateCommnad.Parameters.AddWithValue("@Active", AssignNewActive);
 UPDateCommnad.ExecuteNonQuery();
 GridViewDepartment.EditIndex = -1;
 GetDepartmentList();

}

推荐答案

在网格的RowUpdating事件中

编写此代码，它将获得下拉列表Selected Item

In RowUpdating Event Of the grid

write this code it will get the dropdownlist Selected Item

(GridView1.Rows[e.RowIndex].FindControl("DropDownListName") as DropDownList).SelectedItem ;

检查是否已将下拉列表的"AutoPostBack"属性设置为"True"，并且是否处理了"SelectedIndexChanged"事件.

Check whether you''ve set ''AutoPostBack'' property of dropdown list to ''True'' and ''SelectedIndexChanged '' event is handled.
