如何处理子视图内的链接按钮的Click事件。 [英] how to Handle Click event of link button which is inside child gridview.
问题描述
<pre lang="c#">父网格行绑定事件：
protected void OnRowDataBound（object sender，GridViewRowEventArgs e）
{
if（e.Row.RowType == DataControlRowType.DataRow）
{
string DepartmentID = gvDepartment.DataKeys [e.Row.RowIndex] .Value.ToString（）;
GridView gvCompleated = e.Row.FindControl（gvCompleated ）作为GridView;
GridView gvRunning = e.Row.FindControl（gvRunning）作为GridView;
TaskGateway employeeGateObj = new TaskGateway（）;
gvRunning.DataSource = employeeGateObj.GetTaskTable（DepartmentID）;
gvRunning.DataBind（）;
gvCompleated.DataSource = employeeGateObj.GetPendingTaskTable（DepartmentID） ）;
gvCompleated.DataBind（）;
foreach（gvCompleated.Rows中的GridViewRow gr）
{
if（gr.RowType == DataControlRowType.DataRow）
{
LinkButton lnkbtnresult =（LinkButton）gr.Cells [0] .FindControl（requestID3）;
if（lnkbtnresult！= null）
{
lnkbtnresult.Click + = new System.EventHandler（requestID3_Click）;
}
}
}
foreach（gvRunning.Rows中的GridViewRow gr）
{
if（gr.RowType == DataControlRowType.DataRow）
{
LinkButton lnkbtnresult =（LinkButton）gr.Cells [0] .FindControl（requestID3）;
if（lnkbtnresult！= null）
{
lnkbtnresult.Click + = new System.EventHandler（requestID3_Click）;
}
}
}
}
上面的代码我做了在父网格行绑定，在父网格我有两个子网格视图一个是gvcompleted而另一个是gvrunning，我有每个子网格视图上的链接按钮，但我无法处理链接按钮的点击事件，即使我试图对子网格rowbound和rowcommand事件做但是它们不起作用。
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string DepartmentID = gvDepartment.DataKeys[e.Row.RowIndex].Value.ToString();
GridView gvCompleated = e.Row.FindControl("gvCompleated") as GridView;
GridView gvRunning = e.Row.FindControl("gvRunning") as GridView;
TaskGateway employeeGateObj = new TaskGateway();
gvRunning.DataSource = employeeGateObj.GetTaskTable(DepartmentID);
gvRunning.DataBind();
gvCompleated.DataSource = employeeGateObj.GetPendingTaskTable(DepartmentID);
gvCompleated.DataBind();
foreach (GridViewRow gr in gvCompleated.Rows)
{
if (gr.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnresult = (LinkButton)gr.Cells[0].FindControl("requestID3");
if (lnkbtnresult != null)
{
lnkbtnresult.Click += new System.EventHandler(requestID3_Click);
}
}
}
foreach (GridViewRow gr in gvRunning.Rows)
{
if (gr.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnresult = (LinkButton)gr.Cells[0].FindControl("requestID3");
if (lnkbtnresult != null)
{
lnkbtnresult.Click += new System.EventHandler(requestID3_Click);
}
}
}
}
The above code i did on the parent grid row bound, in the parent grid i have two child grid view one is gvcompleted and another is gvrunning,and i have link button on each child grid view but i am not able to handle click event of link button, even i tried to do on the child grid rowbound and rowcommand event but they are not working.
推荐答案
如果你想得到链接按钮的点击事件那么就有简单的代码，用户RowCommad网格视图事件：
请参阅：
假设gridview类似于
If you want to get the click event of link button then there is simple code, user RowCommad event of grid view:
see:
Assume gridview is like
<asp:gridview id="grvTest" runat="server" xmlns:asp="#unknown">
<asp:templatefield>
<itemtemplate>
<asp:linkbutton id="lnk" runat="server" text="Test" commandname="TestCommand" />
</itemtemplate>
</asp:templatefield>
</asp:gridview>
和你的aspx.cs文件强调RowCommad之类的事件：
and your aspx.cs file contense the event RowCommad like :
Protected Void grvTest_RowCommand(object sender, GridViewCommandEventArgs e)
{
If(e.CommandName == "TestCommand")
{
///Do your code here
}
}
