GridView列宽和换行 [英] GridView Column Width and Wrap

问题描述

你好，

我有UnBound GridView-C#ASP.Net，正在通过查询刷新它.
我有以下代码-

Hello,

I have UnBound GridView - C# ASP.Net and I am refreshing this by query.
I have below code -

SqlDataAdapter adp = new SqlDataAdapter("Select Entry_Date, Emp_Name, Qunatity, Comments From Activity_Master", SqlCon);
System.Data.DataTable dt = new System.Data.DataTable();
adp.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();

我想设置评论"列的列宽"为50，并希望弯曲.

I want to set Column width = 50 of "Comments" column and want Warp.

GridView1.Columns[3].ItemStyle.Width = 50;
      GridView1.Columns[3].ItemStyle.Wrap = true;

这给了我下面的错误.

This gives me below error.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

如何解决这个问题.请帮忙.

How do resolve this. Please help.

推荐答案

绑定网格后，尝试设置列宽和环绕样式.
使用此流程:

Hi,

Try setting your column width and wrapping style after binding the grid.
use this flow:

if(!IsPostBack){
   SqlDataAdapter adp = new SqlDataAdapter("Select Entry_Date, Emp_Name, Qunatity,             
        Comments From Activity_Master", SqlCon);
   System.Data.DataTable dt = new System.Data.DataTable();
   adp.Fill(dt);
   GridView1.DataSource = dt;
   GridView1.DataBind();
}
GridView1.Columns[3].ItemStyle.Width = 50;
GridView1.Columns[3].ItemStyle.Wrap = true;

一切顺利.

All the best..
