Losing Scrollbars when setting GridTableCellStyleInfo properties

[Theo Danzfuss]

I have a custom datasource that I bind to a GridGroupingControl. Before binding to the Custom Source I set some properties on the TableControl for example: this.TableControl.HScrollBehavior = GridScrollbarMode.Enabled

During my custom DataBinding method I make changes to each GridColumnDescriptor''s Style - for example:

GridTableCellStyleInfo gsi = column.Appearance.AnyRecordFieldCell;
gsi.Format = "G";
gsi.CellType = "TextBox";

After setting these proerties my Scrollbars dissapear? If I comment out the gsi.Format or gsi.CellType part I can see my Scrollbars.
In Fact setting ANY property on the GridTableCellStyleInfo causes me to loose my Scrollbars. What am I doing wrong? This is a BIG problem - I cant comment out the part where I Set the GridTableCellStyleInfo becuase then All my Data will be "unformatted" and When putting the code in I loose my scrollbars - then I cant see my data.

Please could you help me ASAP.

Can you tell us how to reproduce this behavior in any of our samples? Or, can you upload a sample showing the problem? If you have a problem uploading, you can email it to [email protected] and mention this forum thread in the subject line.

Do you see any exceptions noted in your output window?

Hi, No there are no Exceptions in the output window. Ill try to replicate it from one of your examples - but Im bit pushed for time right now so I cant promise anything now. Can you think of any reason why this is happening?

To set a format like G in style.Format, the style.CellValueType should also be set to the appropriate system type like typeof(double).

Usually, type problems throw exceptions when you try to put a string into a double or a double into an int, etc.

Hi, I manage to get my grid to work. Here is what happens:

The following piece of code throws away my scrollbars:

TableControl.TableDescriptor.Columns.Clear ( );
foreach ( PropertyDescriptor pd in view.GetItemProperties(null))
{
GridColumnDescriptor gcd = TableControl.TableDescriptor.Columns [TableControl.TableDescriptor.Columns.Add (pd.Name)];
gcd.Appearance.AnyRecordFieldCell.BackColor = System.Drawing.Color.Brown;
}

This piece of code works fine:

TableControl.TableDescriptor.Columns.Clear ( );
foreach ( PropertyDescriptor pd in view.GetItemProperties(null))
{
GridColumnDescriptor gcd = new GridColumnDescriptor ( );
gcd.Appearance.AnyRecordFieldCell.BackColor = System.Drawing.Color.Brown;
TableControl.TableDescriptor.Columns.Add ( gcd );
}

I don''t know why this happens but it seems that when changing a GridTableCellInfoStyle after the GridColumnDescriptor has been added to the Columns collection it "ignores" the scrollbar settings?
