如何从同一页面上的按钮访问gridview控件 [英] how to access gridview controls from a button on same page

问题描述

我有一个包含编辑和删除按钮的gridview.我能够访问这些控件并将其设置为control.Enabled = false.

但是，如何从同一页面的外部按钮执行相同的操作.就像当我单击名为批准交易的按钮时一样.我想禁用网格视图中的添加，编辑和删除按钮.

这是我的代码通过gvjvtemp_RowDataBound
访问控件

Hi,

I have a gridview that contains edit and delete button. I was able to access those controls and set them to control.Enabled=false.

However, how can I do the same thing from a button in the same page but outside. Like when I click a button called approve the transaction. I want to disable the add, edit and delete buttons in the grid view.

here is my code accessing the control via gvjvtemp_RowDataBound

protected void gvjvtemp_RowDataBound(object sender, GridViewRowEventArgs e)
{// added to apply security


#region Check security
//apply security
if (Global.enforceSecurity)
  if (!User.IsInRole("106") && !User.IsInRole("108")) //Lead TARP Accountant / TARP Accountant
  {
    btnAdd.Enabled = false;
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
      if (e.Row.DataItem != null)
      {
        Button EditControl = (Button)e.Row.Cells[0].FindControl("lnkedit");
        Button DelelteControl = (Button)e.Row.Cells[1].FindControl("btndel");

        if (EditControl.Text == "Edit")
        {
          e.Row.Cells[0].Enabled = false;
        }
        if (DelelteControl.Text == "Delete")
        {
          e.Row.Cells[1].Enabled = false;
        }
      }
    }
  }
#endregion
}

谢谢

推荐答案

单击按钮将导致回发，该回发将执行逻辑数据绑定网格并因此再次触发此事件.

您需要做的是设置类级别的变量，您可以在RowDataBound事件处理程序方法中检查该变量，并适当地设置控件.

The button click will cause a postback which will execute the logic for data binding the grid and thus triggering this event again.

What you need to do is set class level variable that you can check in the RowDataBound event handler method and set the controls appropriately.
