Change header text of columns in a GridView

问题

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,

testGV.Columns[0].HeaderText = "Date";

and

this.testGV.Columns[0].HeaderText = "Date";

does not seem to give me correct result.

You should do that in GridView's RowDataBound event which is triggered for every GridViewRow after it was databound.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        e.Row.Cells[0].Text = "Date";
    }
}

or you can set AutogenerateColumns to false and add the columns declaratively on aspx:

<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>

I Think this Works:

 testGV.HeaderRow.Cells[0].Text="Date"

You can do it with gridview's datarow bound event. try the following sample of code:

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

<asp:GridView ID="GridView1" onrowdatabound="GridView1_RowDataBound" >
</asp:GridView>

Create a method protected void method in your c# class called GridView1_RowDataBound

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.

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.

ASPX:

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

CS:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        for (int i = 0; i < e.Row.Cells.Count; i++)
        {
            if (string.Compare(e.Row.Cells[i].Text, "Date", true) == 0)
            {
                e.Row.Cells[i].Text = "Created Date";
            }
        }
    }
}

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
        }
    }
