GGC.RecordExpanded and RecordCollapsed events

[John H]

Hi,
Im using these events and the GGC.TableControl.VScroll property. If the user expands a record the RecordExpanded fires, but the VScroll property is false even though the GGC now has a scrollbar.
How can I reliably tell if the scrollbar is visible in these events?

Thanks
John

Hi John,

Do you want to hide the VerticalScrollbar in a grid? If yes, you should set the TableControl.VScrollBehavior property to GridScrollbarMode.Disabled .Here is a code snippet

this.gridGroupingControl1.TableControl.VScrollBehavior = GridScrollbarMode.Disabled;

Hi Haneef,
No, I want to resize a column accordingly if the scroll bar is visible.

Thanks
John

Hi John,

Here is a knowledge base article that shows you "How to allocate equal size for each of the columns in all the tables of a GridGroupingControl?"

Hi Haneef,
Yeah I saw that example, but it seems overly complex for what should be a simple task? Filtering out everything else in the example (helper class etc), I have implemented the QueryColWidth event as follows;

grid.TableModel.QueryColWidth += new Syncfusion.Windows.Forms.Grid.GridRowColSizeEventHandler( TableModel_QueryColWidth );

and;

void TableModel_QueryColWidth( object sender, Syncfusion.Windows.Forms.Grid.GridRowColSizeEventArgs e )
{
if(e.Index == 3)
{
e.Size = grid.ClientSize.Width - 19;
e.Handled = true;
}
}

when horizontally resizing the GGC, the rows don't repaint correctly?
Also, when expanding a node that contains many rows the scrollbar appears, but the column I resize doesn't adjust accordingly.

Any pointers would be very welcome.

Thanks
John

Hi John,

Sorry for the delay in updating you.

We were not able to reproduce the issue here. Is it possible for you to upload us a sample or modify the any of our browser sample to reproduce the issue here? This will help us to analyse the issue further.

Thanks for your patience.

Hi Haneef,
Sure, I should be able to put together an example.
One thing I forgot to mention is that I have drawn some images in the TableControlDrawCell event for the column that is to be resized, using e.Inner.Bounds.Width - 35 as the firsts left position.

Does this help?

Thanks
John

Hi Haneef,
I have attached an example project that displays 2 icons in the top level row, and I have implimented QueryColWidth as per the example.

If you resize the form you will see that the icons are not painted correctly, and if you expand node 2 and then one of its child nodes so that the scroll bar appears, you can see that the top level column widths are not resized and so the right most icon is obscured by the scroll bar.

Thanks
John

Hi Haneef,

The example you posted doesn't resolve the repainting issue when you drag the form wider or smaller, or the problem where the right most icon is covered by the scrollbar when you expand Table2 node and a child node.

Any ideas?

Thanks
John

Hi John,

Thanks for being patience.

Before draw the icon in a grid cell, you should check table cell identity of the cell and also you should check the drawing point of the error icon. Please find the code snippet for drawing the error in a cell.

void NavParent_DrawCell(object sender, GridDrawCellEventArgs e)
{
GridTableControl tc = sender as GridTableControl;
int filed = tc.TableDescriptor.ColIndexToField(e.ColIndex);
GridTableCellStyleInfo style = tc.GetTableViewStyleInfo(e.RowIndex, e.ColIndex) as GridTableCellStyleInfo;

//before draw a cell, you need to check Table cell identity.
if ((style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell
|| style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
&& (tc.TableDescriptor.Columns.Count > filed))
{

string columnName = tc.TableDescriptor.Columns[filed].Name;
if (columnName == "group")
{
e.Renderer.Draw(e.Graphics, e.Bounds, e.RowIndex, e.ColIndex, e.Style);

Icon failureIcon = SystemIcons.Error;
Icon warningIcon = SystemIcons.Warning;
//Also you can check the drawing point of the icon....
Rectangle iRect = new Rectangle(e.Bounds.X, e.Bounds.Y, e.Bounds.Width/2,e.Bounds.Height);
e.Graphics.DrawIconUnstretched(failureIcon, iRect);
e.Cancel = true;
}
}
}

Hi Haneef,
your example fixes the repaint issue, thanks.
But it doesn't fix the problem when the icon is being drawn to the right of the Description column, and then expand nodes until a scrollbar appears. Do you have a property I can check to see if the scrollbar is visible?

I have modifed the example to show you what I mean.

Thanks
John

Hi Haneef,
I found the grid.TableControl.VScroll property, which does what I need, thanks.
