c# - net - Change header text of columns in a GridView




how to set header text dynamically gridview in c# (4)

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";
            }
        }
    }
}

I have a gridview which i bind programmatically with c# code. The problem is, the columns get their header text directly from db which can look odd on websites, so i would like to change that but programmatically with c# code. i have already tried,

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

or

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

does not help.


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";
}
}

For more details about the row databound event study Thsi....


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>
