Suppress cell combo box

[Richard]

I have columns of Combo Boxes in my grid, and I want to suppress the drop down on the combo from appearing when the cell is read only, here is the code that I have so far

private void GroupingGrid_TableControlCellClick(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellClickEventArgs e)
{
int intCol;
intCol = (e.Inner.ColIndex - this.GroupingGrid.TableDescriptor.GroupedColumns.Count) - 1;

// check to see if this is an add new record row,
GridTableCellStyleInfo style = e.TableControl.Model[e.Inner.RowIndex, e.Inner.ColIndex] as GridTableCellStyleInfo;
if(style != null && style.TableCellIdentity.TableCellType == GridTableCellType.AddNewRecordFieldCell)
{
if (this.GroupingGrid.TableDescriptor.Columns[intCol].Name == "Class")
{
GroupingGrid.TableDescriptor.Columns["Class"].ReadOnly = false;

}
}
else
{
// make sure this is the correct column
if (this.GroupingGrid.TableDescriptor.Columns[intCol].Name == "Class")
{
GroupingGrid.TableDescriptor.Columns["Class"].ReadOnly = true;
}
}
}

I can successfully turn the read only on and off, but how do I also suppress the drop down

Try handling the QueryCellStyleInfo event.

In your handler, if e.TableCellIdentity points to the cell you want to make readonly and not show a combobox, you can set e.Style.ReadOnly = true and e.Style.ShowButtons = GridShowButtons.Hide.

Is there any way, I can just do this once for the whole column, eg
grid.TableDescriptor.Columns[GetMappedName("SomeColumn")].ReadOnly = true;

that does the readonly, but there does not seem to be an equivalent for the showbuttons.

I really would like to avoid using querycellstyleinfo if possible

You can use:

grid.TableDescriptor.Columns[GetMappedName("SomeColumn")].ShowButtons = GridShowButtons.Hide;

But if you have earlier set the ReadOnly property = true, you will need to ttemporarily set

grid.IgnoreReadOnly = true;

so you can make changes to the style.

This does not compile, I get the error
Syncfusion.Windows.Forms.Grid.Grouping.GridColumnDescriptor does not contain a definition for ShowButtons

I am using version 3.201.1.1

Sorry. GridShowButtons is a style property. So, look for it under the column''s Appearance property.

grid.TableDescriptor.Columns[GetMappedName("SomeColumn")].Appearance.AnyRecordFieldCell.ShowButtons = GridShowButtons.Hide;
