[Solved] Difference in font between Checked and Unchecked checkbox

I have a couple of checkboxes on a page that is decorated by RadFormDecorator.

I notice that the font associated with the checkboxes changes slightly when the checked property changes. This is with 2010.2.713.

Looking at the page using IE8's developer tools shows that there are some additional CSS properties applied when the checkbox is checked.

You can see what I mean by comparing the 2 images attached.

[Solved] how do I set the page focus to the insert button after clicking the add new record button to add a record

I have a telerik radgrid that has an allows inserts. After clicking the "Add New Record" button the textboxes appear with a couple of buttons. One for Insert and one to cancel. I would like the page focus to be on the insert button so when the user clicks the enter button, the insert button has the focus.

Does anyone know how to do this?

[Solved] EditForm Double Binding

Hi,
After using telerik RadGrid Edit form. Which within our custom user control contains a ComboBox (Data Source: DataTable, AppendItemDataBound: True). It appears that the combobox has double bind the value. I have attached a sample code which duplicated the scenario im describing.

ddl.AppendDataBoundItems = true;

ddl.Items.Add(new ListItem("select one", ""));

ddl.DataTextField = "Value";

ddl.DataValueField = "ID";

ddl.DataSource = Session["DataTableSource"];

ddl.DataBind();

RadComboTest.AppendDataBoundItems = true;

RadComboTest.Items.Add(new RadComboBoxItem("select one", ""));

RadComboTest.DataTextField = "Value";

RadComboTest.DataValueField = "ID";

RadComboTest.DataSource = Session["DataTableSource"];

RadComboTest.DataBind();

the above code is invoked one during Page Load (userControl, that is invoked by radGrid). however the behaviour of having appenddatabound is for us to Add "Select One" item is desired. Is there a reason why its duplicating ?

Best Regards,
Adrian

From my own personal point of view, the upgrader is really of beta quality. It is NOT dependable.

My project was 99% complete and now I can't demo so much as a start page if the suits come calling. Not good.

Thanks,

[Solved] Grid Filter error, Syntax error: Missing operand after '["column"]' operator.

Hi I recently upgraded to Version=2010.1.519.40 afterwards we started getting this Grid Filtering error;
"Syntax error: Missing operand after '["column"]' operator."

We get a different error when filtering an INT column:
"The expression contrain undefined function call Convert.ToDecimal()."

Then to top it off when leaving the page we get a "null object" error but only when the grid is filter, sorted, or grouped by using the HeaderContextFilterMenu. If you turn this feature off and sort, filter, or group by the default method it doesn't throw this error.

I am not sure what changed but this is a deal breaker for us. We wil most likely have to roll back so any help would be greatly appreciated.
Thanks

RadGrid select and grouping feature not working on next rebind of RadGrid

Hi,

I have created a RadGrid (_grdDocuments) inside RadAjaxPanel. I just need to enable multi-row selection and grouping in that RadGrid so below are the codes I have used. Data of the RadGrid is gathered thru a dropdown value say (Company1, Company2, Company3).

Initially when data is loaded in the RadGrid, you can select a row or even group the grid based on the dragged column name.

Now when you change the value of the dropdown say Company 2, you cannot select or group in the Grid anymore. Why? Am I missing something here?

This is WSS 3.0 WebPart application. No client or server events attached.

I am using Telerik version 2008.3.1314.35

Thanks
