Hi All,

OK I am feeling somewhat stupid at the moment. I have a Windows forms app with a datagrid on it. In the menu I have an option to allow the user to resync the database with my main SQL database. It uses merge replication and it all works fine. The problem that I am having is stupidly simple by comparison to the task of syncing the data. Once the syncronisation has finished, I need the datagrid to repopulate itself with any changed data. 2 minute job I thought, an hour later I still am having issues!

There are some threads discussing what I think is the same issue but people seem to be missing the stick and talking about setting the datasource to null and then reconnecting it. Well that works but the RadGrid seems to then add in all of the hidden ID columns etc again.

Surely there is a command like Refresh (what does that do anyway? does it just redraw the grid?) that works on this. On Asp.Net Refresh does as you'd expect and refreshes the data in the grid.

All I want to do is tell the grid to reload it's data!

Any ideas anyone?

Regards,

Jon

[Solved] Multicolumn combo box filtering syntax

Hello,
I'm trying to set a filter expression for my MultiColumn combo box. I use the following syntax.

MultiColumnComboBox1.DataSource = DataTable1
MultiColumnComboBox1.DisplayMember = "Iso2"
MultiColumnComboBox1.ValueMember = "Iso2"

MultiColumnComboBox1.MultiColumnComboBoxElement.AutoSizeDropDownToBestFit = True

Dim fe As FilterExpression

fe = New FilterExpression(MultiColumnComboBox1.DisplayMember, FilterExpression.BinaryOperation.AND, GridKnownFunction.StartsWith)

MultiColumnComboBox1.EditorControl.MasterTemplate.FilterDescriptors.Add(fe)

MultiColumnComboBox1.MultiColumnComboBoxElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend

MultiColumnComboBox1.AutoFilter = True

When entering a single letter ito the box, e.g. an "L" the filtered result contains all elements which contains an "L", not only thos which start with an "L". Did I use the parameter GridKnownFunction.StartsWith correctly?

Any help is appreciated.
Sincerely Roberto

[Solved] RadListControl Selection Issues When Re-Ordering

When SelectionMode is set to 'MultiExtended' the RadDataItem.Selected property will behave as if the Mode is 'One' (clear all other selections).

When SelectionMode is set to 'MultiSimple' and a RadDataItem is added witht the Selected property set to true then the RadDataItem will always show as selected but cannot actually be selected or de-selected. Also when the list is re-ordered then ActiveItem does not stay on the RadDataItem that was active before the re-order.

I mean, something like:

Scheduler.Appointments.Add(DATE,HOUR,EVENT)

Thanks.

FillType not working correctly

I have a very simple radChart and I am attempting to set the Fill Type to Gradient and use two KnownColors as the Main and Secondary Color. I have tried to do this progamatically and through the property panel. When setting the property in the property panel from Solid to Gradient it immediately goes back to gradient, however I am able to set it to hatched. Here is the code I am using. The is still solid white. Any help would be greatly appreciated.

KnownColor clrTopBackgroundColor = KnownColor.White;

KnownColor clrBottomBackgroundColor = KnownColor.LightBlue;

radChart1.PlotArea.Appearance.FillStyle.FillType = FillType.Gradient;

radChart1.PlotArea.Appearance.FillStyle.MainColor = Color.FromKnownColor(clrTopBackgroundColor);

radChart1.PlotArea.Appearance.FillStyle.SecondColor = Color.FromKnownColor(clrBottomBackgroundColor);

radChart1.Update();

radChart1.UpdateGraphics();

Thank you,
Will

RadGridView Filter - 'Contains' option required on numeric column

Hi
Is there any way that I can override the default RadGridView Filter behaviour where the 'Contains' option is not presented for numeric fields?
I need the 'Contains' option to appear on a numeric column. I know that I could change the datatype on the table but that's not really an option for me.
I am a licensed user of RadControls for WinForms Q1 2010 SP2.
Any help is appreciated.
Thanks
