如何隐藏ASP.Net Gridview列 [英] How to hide ASP.Net Gridview column

问题描述

大家好，下面的代码假设要隐藏一列，但它给了我这个错误:

Hi guys, code below suppose to hide a column but its giving me this error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Source Error:


Line 28:         if (grdAvailableStuff.Columns.Count > 0)
Line 29:         {
Line 30:             grdAvailableStuff.Columns[2].Visible = false;
Line 31:
Line 32:

检查下面的代码，我不了解发生了什么

Check the code below, I dont knw what hapend

if (grdAvailableStuff.Columns.Count > 0)
       {
           grdAvailableStuff.Columns[2].Visible = false;


       }
       else
       {
           grdAvailableStuff.HeaderRow.Cells[2].Visible = false;


           foreach (GridViewRow grd in grdAvailableStuff.Rows)
           {
               grd.Cells[2].Visible = false;


           }
       }

推荐答案

此处

grdAvailableStuff.Columns [2] .Visible = false;

表示您正在隐藏网格视图的第三列.

确保网格视图呈现3列或3列以上.

here

grdAvailableStuff.Columns[2].Visible = false;

Means your are hiding 3rd column of grid view.

Make sure that grid view renders with 3 or more than 3 columns.

尝试一下

Try this

protected void grdAvailableStuff_RowCreated(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header)
           {
               e.Row.Cells[1].Visible = false;
              
           }
       }
