Change header text of columns in a GridView
提问by Mana
I have a GridView which i programmatically bind using c# code. The problem is, the columns get their header texts directly from Database, which can look odd when presented on websites. So basically, i would like to modify the column header text, but programmatically. i have already tried the following,
我有一个使用 c# 代码以编程方式绑定的 GridView。问题是，这些列直接从数据库中获取其标题文本，这在网站上呈现时可能看起来很奇怪。所以基本上，我想以编程方式修改列标题文本。我已经尝试了以下方法，
testGV.Columns[0].HeaderText = "Date";
and
和
this.testGV.Columns[0].HeaderText = "Date";
does not seem to give me correct result.
似乎没有给我正确的结果。

You should do that in GridView's RowDataBoundevent which is triggered for every GridViewRowafterit was databound.
您应该在 GridView 的RowDataBound事件中执行此操作，该事件在数据绑定GridViewRow后每次都会触发。
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "Date";
}
}
or you can set AutogenerateColumnsto falseand add the columns declaratively on aspx:
或者您可以设置AutogenerateColumns为false并在 aspx 上以声明方式添加列：
<asp:gridview id="GridView1"
onrowdatabound="GridView1_RowDataBound"
autogeneratecolumns="False"
emptydatatext="No data available."
runat="server">
<Columns>
<asp:BoundField DataField="DateField" HeaderText="Date"
SortExpression="DateField" />
</Columns>
</asp:gridview>

You can do it with gridview's datarow bound event. try the following sample of code:
您可以使用 gridview 的数据行绑定事件来完成。尝试以下代码示例：
protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "TiTle";
}
}

On your asp.net page add the gridview
在您的 asp.net 页面上添加 gridview
<asp:GridView ID="GridView1" onrowdatabound="GridView1_RowDataBound" >
</asp:GridView>
Create a method protected void method in your c# class called GridView1_RowDataBound
在名为 GridView1_RowDataBound 的 c# 类中创建一个方法 protected void 方法
as
作为
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "HeaderText";
}
}
Everything should be working fine.
一切都应该正常工作。

I Think this Works:
我认为这有效：
testGV.HeaderRow.Cells[0].Text="Date"

Better to find cells from gridview instead of static/fix index so it will not generate any problem whenever you will add/remove any columns on gridview.
最好从 gridview 中查找单元格而不是静态/修复索引，这样无论何时您在 gridview 上添加/删除任何列都不会产生任何问题。

ASPX：
<asp:GridView ID="GridView1" OnRowDataBound="GridView1_RowDataBound" >
<Columns>
<asp:BoundField HeaderText="Date" DataField="CreatedDate" />
</Columns>

protected void grdDis_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
#region Dynamically Show gridView header From data base
getAllheaderName();/*To get all Allowences master headerName*/
TextBox txt_Days = (TextBox)grdDis.HeaderRow.FindControl("txtDays");
txt_Days.Text = hidMonthsDays.Value;
#endregion
}
