Boolean column in GridView and DB

Hi,

One of my DB column is a char(1). I use it to report "y" or "n" for a row.
I've added GridView which has a combobox column.

I used dataset to connect between the two.
How to I change the "true" of "false" which the combobox returns to a "y" or "n" value?

Now when I change the value of "Active" combobox (see image attached), an exception thrown "Cannot set column 'bool_active'. The value violates the MaxLength limit of this column."

Label AutoSize not working

Hi

I'm using version Q3 2009 SP1.

I have a RadLabel (with AutoSize = True) on a form I use to indicate loading status. I constantly change the Text in the RadLabel during the loading phase. The problem is that the size of the RadLabel does not change after I set the Text.

The workaround is that I have to do the following:

                    lblLoading.AutoSize = false;         
            lblLoading.Text = _loadingText;         
            lblLoading.AutoSize = true;         

Also I've noticed that it does not work out the correct size of the RadLabel if the form is not shown (even with the above workaround).

So the following code snippet will not work, I need to move the setting of LoadingText to after the Show().

                    frmLoading loadingForm = new frmLoading();         
            loadingForm.LoadingText = "Validating License...";         
                     
            loadingForm.Show();         

Are these bugs or am I missing something?

SelectedValue not set in DropDownList

Hi guys,

I'm in the process of upgrading the previous RadComboBox from 2009 to the newest version and I encountered a weird behaviour with the new RadDropDownList. ( note: this also affects RadComboBox in the newest version)

I did a simple test by binding the controls to a strongly typed datatable, setting the valuemembers and display members and then set the default value to 1 of the items that exist in that table. -

Listed below are code snippets from the old RadComboBox (2009) and the new RadDropDownList.

2009 version of the code which works. - The end result of this is that when the combobox is loaded, the default selected value is Australia. If I just refactored the code by changing this RadComboBox to a RadDropDownList and try to Debug it right after the box.SelectedValue = "Au"; shows that the selectedValue is still null.

RadComboBox box = new RadComboBox();

box.ValueMember = "Code";

box.DisplayMember = "Name";

box.DataSource = [StronglyTypedCountryDataTable] // this table contains columns code, name

box.SelectedValue = "Au";

After upgrading to the new 2011 version, the above mentioned code doesnt work any more. when the control is loaded, it always displays the 1st item in the box ("Afghanistan") even when the selected value has been set to Au. I tried changing the datasource to a List, DataView and the same behaviour exists.

Finally, I tried adding the items manually and it worked...

2011 version -

RadDropDownList list = new RadDropDownList();

list.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

Country country = Country.Get();

list.ValueMember = "Code";

list.DisplayMember = "Name";

foreach (CountryBe.CountryRow row in country.BusinessEntity.Country)

{

list.Items.Add(new RadListDataItem(row.Name,row.Code));

}

list.SelectedValue = "Au";

Can someone explain to me why the 1st method of implementation doesnt work the same as the 2nd method?

Central alignment of RadRibbonBarGroup in RibbonTab

Hi Guys,

I wonder if anyone can help? We are converting our application to use the Telerik RibbonBar (2009 Q2) and a request has come through for the groups to be centrally aligned in the tabs rather than to the left. I have had a play about with all of the alignment properties I can find for the RadRibbonBarGroup objects and the RibbonTab objects, but I can not get the groups to do anything but 'float' to the left.

Is there a way to align them centrally?

Any help appreciated.

Best regards,
Duane.

Extract theme properties

Hi. I have a CommandBarButton that I would like to set the backcolor to whatever the "hover" backcolor is for the current theme. (This is a visual cue to the user and a toggle button is not appropriate). I have tried using button.SetValue and button.ResetValue but I can't seem to find out what the backcolor is for the hover state.

Is it possible at runtime to extract properties for certain states from a theme?

Thank you!

Conflict between different versions of the same dependent assembly

After upgrading to Q1 2011 I get a warning saying: Found conflicts between different versions of the same dependent assembly.

Doubleclicking brings out this message: One or more dependent assemblies have version conflicts. Do you want to fix these conflicts by adding binding redirect records in the app.config file?

Anwering "yes" adds these records in the file:

When attemting to run I get the following error:

Could not load type Telerik.WinControls.Primitives.RectanglePrimitive from assembly Telerik.WinControls, Version=2011.1.11.315, Culture=neutral, PublicKeyToken=5bb2a467cbec794e

Then I get "No source available, no symbols are loaded for any call stack fram, the source code can not be shown". Frustrating...

I have tried removing and adding all the references to Telerik dll's, but I still get the error. Any help is appreciated!
