Hi ,

What you mean with the column name?

The DataGrid.Columns is a collection of DataGridColumn's derived classes,
what you can change is the HeaderText property of it.

You cannot access a column by name, only by index.

Hope this help,
 
I'm not sure I understand.

I have this code:
DataSet DSAtt = new DataSet();
OdbcDataAdapter DA2 = new OdbcDataAdapter(mySql2, myConnection);
DA2.Fill(DSAtt, "pearht");
DataGridAttendance.DataSource = DSAtt.Tables["pearht"];
DataGridAttendance.DataBind();

What would I need to add to change the Header text of each of these columns?
Thanks.
 
Hi,

You can use the DataGrid.Columns[ index].HeaderText

You will have to do it AFTER you call DataBind()

Pd:
If you are using TemplateColumn as the columns you better use the
<HeaderTemplate> section in the aspx page.

Hope this help,

I tried that before (with the example you gave me on how to change column
height) but I get :

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

To change one column, I use
DataGridAttendance.Columns[0].HeaderText = "From Date";

The columns are automatically generated depending on the result of my query.
I'm not declaring any columns.

I tried to rename the column names in the Oracle select but the ODBC driver
doesn't recognize it.

Hi

Are you declaring your columns ?
If they are automatically generated you can not use Columns for this.

How are you defining your grid in the aspx page?

From MSDN:
Explicitly declared columns may be used in conjunction with automatically
generated columns. When using both, explicitly declared columns will be
rendered first, followed by the automatically generated columns.
Automatically generated columns are not added to the Columns collection.

Hi,

Try to set the columns as this in the ASP.NET page:

<Columns>

<asp:BoundColumn
HeaderText="Item"
DataField="StringValue"/>

<asp:BoundColumn
HeaderText="Price"
DataField="CurrencyValue"
DataFormatString="{0:c}">

<ItemStyle HorizontalAlign="right">
</ItemStyle>

</asp:BoundColumn>

Cheers,
