在另一个gridview里面的gridview里面找不到控件的id [英] Cannot find id of control inside gridview which inside another gridview

问题描述

任何人都可以帮我这个吗？

我在GridView（gvSdt）中有一个按钮（ImageButton1），而gridview b在另一个Gridview（gvClass）中。

但它出现了一个错误，当前上下文中不存在名称'gvSdt'

我使用的代码如下：

Can anyone help me on this?
I have a button(ImageButton1) inside a GridView (gvSdt), and gridview b is inside another Gridview (gvClass).
but it come out an error said "The name 'gvSdt' does not exist in the current context"
The code i used as below:

protected void gvSdt_SelectedIndexChanged（object sender，EventArgs e）

{

GridViewRow row = gvSdt.SelectedRow;

int rowIndex = gvSdt.SelectedIndex;

string strValue = gvSdt.DataKeys [rowIndex] .Value.ToString（）;

}

protected void gvSdt_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = gvSdt.SelectedRow;
int rowIndex = gvSdt.SelectedIndex;
string strValue = gvSdt.DataKeys[rowIndex].Value.ToString();
}

谢谢。

Thank you.

推荐答案

尝试将发件人转换为GridView

try to cast sender as GridView

GridView gvSdt = sender as GridView;
GridViewRow row = gvSdt.SelectedRow;

试试这个

Try this

protected void gvSdt_SelectedIndexChanged(object sender, EventArgs e)
{
       GridView gv = sender as GridView;
       if (!Equals(gv, null))
       {
           int rowIndex = gv.SelectedIndex;
           string strValue = gv.DataKeys[rowIndex].Value.ToString();
           // Do your stuff here
       }
       else
       {
           // Generate error message here
       }
}
