如何在GridView中设置LinkBut​​ton的可见性 [英] How to set the visibility of a LinkButton in a GridView

问题描述

你好

我有一个绑定到SqlDataSource的GridView，并且想尝试根据该行中列的值来设置LinkBut​​ton的可见性，例如:

如果ACTION_STATUS列为12(关闭)，那么我想隐藏LinkBut​​ton，我知道我应该能够使用LinkBut​​ton.Visible = false;.为此，但不确定如何检查ACTION_STATUS的值

我也希望能够在页面后面的代码中处理所有这一切.

一如既往，任何帮助将不胜感激.

谢谢

Pete

Hello

I have a GridView bound to a SqlDataSource and would like to try and set the visibility of a LinkButton based on the value of column in that row for example:

If Column ACTION_STATUS is 12 (Closed) then I want to hide the LinkButton I know I should be able to use the LinkButton.Visible = false; to do this, but not sure how to check the value of ACTION_STATUS

I want to be able to handle all this in the code behind page too.

As ever any help would be most appreicated.

Thanks

Pete

推荐答案

嗨 这很简单，其中e.Row.Cells [ 0 ]是您的ACTION_STATUS索引 clumn

Hi it''s very simple where e.Row.Cells[0] is index of your ACTION_STATUS clumn

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if ((Convert.ToInt32(e.Row.Cells[0].ToString()) == 12))
            {
                HyperLink hy = (HyperLink)e.Row.FindControl("HyperLink");
                hy.Visible = false;
            }
        }

如有任何疑问，请让我知道.

首先，您需要找到链接按钮在哪一列中.

然后，在找到之后，按如下方式提到行数据绑定事件中的单元格号.

Hi,

First you need to find the link button is there in which column.

Then after finding,mention that cell no in row databound event as follows.

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if ((Convert.ToInt32(e.Row.Cells[0].ToString()) == 12))
            {
                HyperLink hy = (HyperLink)e.Row.FindControl("HyperLink");
                hy.Visible = false;
            }
        }

如果仍然出错，请检查链接按钮单元格的索引位置代码或调用Gridview的行数据绑定事件的代码.

If you are still getting error, please check code for index position of linkbutton cell or where you are calling row databound event of Gridview.

Gridview_RowDataBound(..)
{
if(e.Row.cell ["ACTION_STATUS"].Text == 12)
{
(((LinkBut​​ton)e.Row.FindControl(& quot; LinkBut​​toVisible = false;
}
}

Gridview_RowDataBound(..)
{
if( e.Row.cell["ACTION_STATUS"].Text == 12)
{
((LinkButton)e.Row.FindControl("LinkButtoVisible = false;
}
}
