如何根据行条件禁用网格视图中的编辑模式。 [英] How to disable the edit mode in grid view based on row condition.

问题描述

我有一个名为sign off的列，如果列值为Yes，则网格视图行不应该是可编辑的。



什么我试过了：

I have a column called "sign Off" and if the column value is "Yes" then the grid view row should not editable.

What I have tried:

protected void grdChangeRequirement_RowCommand(object sender, GridViewCommandEventArgs e)
   {
       GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
       Label myTextBox = row.FindControl("lbl_SignOff") as Label;

       if (myTextBox.ToString() == "Yes")
       {
           Label btnUpdate = row.FindControl("btn_Update") as Label;
           Label btnCancel = row.FindControl("btn_Cancel") as Label;

           btnUpdate.Visible = false;
           btnCancel.Visible = false;
       }

   }

推荐答案

使用RowDataBound [ ^ ]活动



标签控制你必须使用 Text 属性来读取文本值

我怀疑命令按钮不是标签，它应该是按钮或链接按钮控件。请检查并更改转换控件

use RowDataBound[^] Event

for label control you will have to use the Text property to read the text value
I suspect the command buttons are not labels, it should be a button or linkbutton control. please check that and change the casting control

void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow) {
               GridViewRow row = (GridViewRow)e.Row;
               Label myTextBox = row.FindControl("lbl_SignOff") as Label;
               if (myTextBox.Text == "Yes")
               {
                   LinkButton btnUpdate = row.FindControl("btn_Update") as LinkButton;
                   LinkButton btnCancel = row.FindControl("btn_Cancel") as LinkButton;

                   btnUpdate.Visible = false;
                   btnCancel.Visible = false;
               }
           }


       }
