How do I make the header in the GridDataBoundGrid invisible?

[Atith Pagdi]

I''m using the GDBD to show some data to the user by binding it to a dataset. I need to set one of the column header''s property to invisible. How do I do this? Could someone give me the code snippet since I''ve tried finding an attribute to do this and have been unsuccessful so far.

Thanks!

You can set the HeaderText property on the GridBoundColumn for the column to be one space (setting it to be teh empty string will not work).

//if you haven''t added GridBoundColumns
this.gridDataBoundGrid1.Binder.InternalColumns["Col1"].HeaderText = " ";

//or if you added GidBoundColumns...
this.gridDataBoundGrid1.GridBoundColumns["Col1"].HeaderText = " ";

I tried that Clay, but it still doesn''t work. There''s no change in the header text. This would however just make the text = "", but I want the column header itself to be invisible. How can we do this? I was trying the following code...

GridTableCellStyleInfo style = e.TableControl.Model[e.Inner.RowIndex, e.Inner.ColIndex];
if(style.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell)
{
if(style.TableCellIdentity.Column != null && style.TableCellIdentity.Column.Name == "Product")
e.Inner.Cancel = true;
}

but wasn''t able to find a reference to the GridTableCellStyleInfo class. Which namespace do I need to include for this class? (using...)

Thanks.

Hi
If your intension is to make the particular column header invisible , you can try the following code in the PrepareViewStyleInfo() event.

if(e.ColIndex >= 1 && e.Style.CellType == GridTableCellType.ColumnHeaderCell.ToString())
{

if(this.gridDataBoundGrid1.Model.NameToColIndex("Product") == e.ColIndex)
e.Style.CellType = GridTableCellType.None.ToString();

}

Hi,

I tried the code suggested by you, but the column header is still visible. I''ve been trying to do this for a couple of days now. Is there any other way we can handle this?

Thanks,

Also, on trying this... the NameToColIndex method returns the value 28 to me when there are no more than 10 columns in the grid. I have specified the layout of the datarow in the PrepareStyleInfo handler to be a multi row record. Do you think this could have anything to do with it?

Thanks,

You want to drawn an empty hole where the header cell is located, correct? Here is a sample using QueryCellStyleInfo.

Clay,

That''s for the GridGroupingControl. I''m trying to achieve this with the GridDataBoundGridControl.

The reason I thought you had changed to a GroupingGridControl is above you listed code like:
GridTableCellStyleInfo style = e.TableControl.Model[e.Inner.RowIndex, e.Inner.ColIndex];

You use the model.QueryCellInfo event in a GridDataBoundGrid and do the same thing.

Thanks Clay... your previouos suggestion, with some tuning did the trick for me. Thanks for your feedback.
