How do you force a calculated column in the GridView to refresh without reloading data, if a column is changed by a user that is part of the calculated column expression?

Thanks...Bill

I am using Q3 2008 and have created a toolstrip that has several buttons on it and 2 splitbutton controls.

I have set screentips for all the buttons and splitbuttons , however the screentips on the splitbuttons never show themselves whereas the button screentips always work. What will I need to do to get the screentips on the dropdowns working ?

Hi,

I have a MultiColumnComboBox and I set (both in Property Builder) and in properties -> EditorControl -> MasterGridViewTemplate the columns to only have two against the bindingsource I have speficied, however all the columns are added at runtime.  I have manually changed the AutoGenerateColumns on the EditorControl -> MasterGridViewTemplate in code but still it auto generates the columns.

Any help appreciated.

I'm currently using the demo controls to develop my application.

I have 3 combobox the first is populated on load and the next one is populated based on the first and the third based on the selection in the second drop down.

One the user selects the first 2 combobox selections I query my oracle db and set the datasource of my first grid to that data table.
If the user changes the 3rd combbox then I filter the data in my datatable and rebind.  My problem on the rebinding is the issue of my checkbox column.  The checkboxes do not clear out when I rebind.  I've tried deleting the column and readding it but then my data doesn't bind all I see is the checkbox column.

What is suppose to happen when a user selects a checkbox is the second datagrid is populated based on their selection.  They can check multiple rows.  The second data grid will also have a checkbox column that I will use to  generate a report.

My main problem is when I have to clear my grids and rebind the checkbox column doesn't seem to work correctly.

Please any help would be greatly apprciated.

This is my code to remove and readd the checkbox column to my first grid. Which isn't working.

Anything that can point me in the right direction would be greatly appreciated.  I'm on a time constraint and am trying to verify I can do all this with the telerik controls.

I have been noticing that on your RadForm there is a problem with how you get your GetDCEx. To keep it short I'll give you a short piece of code that can help you.

public

static IntPtr GetDC(Message msg)

 

{

 

 

if (msg.Msg != (int)WindowMessages.WM_NCPAINT)

{

 

return GetWindowDC(msg.HWnd);

}

 

int flags = (int)(DCX.DCX_CACHE | DCX.DCX_CLIPSIBLINGS | DCX.DCX_WINDOW );

 

IntPtr zero = IntPtr.Zero;

 

 

if (msg.WParam.ToInt32() != 1)

{

flags |= (

 

int)DCX.DCX_INTERSECTRGN;

 

 

zero = msg.WParam;

 

 

}

return GetDCEx(msg.HWnd, zero, flags);

}

 

I have a column that is defined as GridViewCheckBoxColumn  I'm able to check the checkboxes and the code behind does what it's suppose to do.  My problem is when I filter another column the checked rows stay checked but the data for that row has changed.  When I try and do it programmically every time I do the following

The  radGVTables_ValueChanged event fires and it is looking for the rowindex.   But since it was the filter that was selected the rowindex is -1.

1. Is there a way to change the rowindex or cycle through the rows?

2. Is there a way to clear out all the checked checkboxes?

3. How have others handled Checkboxes and Filters?

Thank You

Hey Telerik,
I wanted to ask - have you seen any issues with this?  I have a Radtreeview inside a RadRibbonForm, and when I show a large context menu for the point in the treeview I'm clicking, it often will show "behind" the windows taskbar.  This only seems to occur after the RadRibbonForm has been resized/maximized, minimized.

Can anyone let me know if you've seen this and if you have a work around?  We're running Radcontrols for Winforms 2008 Q3.

Thanks!

Jim

Very new to the winforms component, am builiding my first app and all is going well however pretty much every control has a blue background when I run my app. I don't see this in the designer and have no idea where this setting is coming from.

Help?

Hi,

I have the problem theming a RadTitleBar on a ShapedForm.

What I did:
0. created a new default WinForm-Project
1. added all the Telerik-dlls to the project and changed the Form to a ShapedForm
2. added a RadTitleBar
3. added the file RadTitleBarVista.xml from the Telerik VS2008 C# Examples project as a embedded resource.
4. added a RadThemeManager and added the xml-file to it (StorageType: Resource)
5. selected the now appearing Vista-theme to the RadTitleBar: the design view changed and the RadTitleBar has the Vista-Theme applied.
6. Compiled and started the application: The RadTitleBar now has the Office2007Blue or default-theme(???)
7. I also tried setting the ThemeName to "Vista" in the FormLoad-Method with no effect.

Fyi, I'm using VS 2008 on Vista (32 bit).

How can I get the Vista-Theme on the RadTitleBar? What am I doing wrong?

Thanks in advance!
