RAD Combobox intermittentent Errors for Non Existing Values

Hi,

We have sometimes been getting errors when we assign the selected value of a RAD combobox to a value that does not exist within the combobox. Firstly we do have a workaround for this however:
- we would like to know why the error occurs intermittentently and whether we can permently fix problem without the extra workaround code
or
- how to turn of the function to set the selected index to 0 if the combobox is assigned a non-existent value so we would see an error everytime

Note: the RADCombo.ClearSelection() function does not fix the problem.

Help greatly appreciated.
Thanks

Problem biding Huge dataset

Hi,

I am working for a project which requires us to bind a large dataset of minimum of 5000 records - not to forget the columns that need to be displayed as well - 40 columns around.

Binding to Grid is fine - automatic paging is enabled with page size of 100 or whatever. Now the trouble is clicking for next page throws an error. I testing for around 4000 records it works fine but if it is larger than 5000 records, I am getting the following error

"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occured while processing the request on the server. The status code returned from the server was: 12031"

Can someone tell me what is going on? Is it the limitation of the grid itself.

Any help is appreciated.

Many thanks.

SubMenu/ Multi-level menu issue in rad tree context menu

When i use this xml in contextmenu xml file i get menu successfully attached to NODE1 of rad tree view.

<ContextMenus>
    <Menu Name="NODE1" Width="150">
        <Item Text="Expand All" />
        <Item Text="Redraw Tree" />
    </Menu >
</ContextMenus>

But if i want sub menu too in my context menu, this is how i modify my xml . But then i am only getting first level menu items and not getting second level menu items.

<ContextMenus>
    <Menu Name="NODE2" Width="150">
        <Item Text="Add" >
            <Menu >
                    <Item Text="Page" />
                    <Item Text="Table" />
            </Menu >
        </Item >
        <Item Text="Redraw Tree" />
    </Menu >
</ContextMenus>

Is there some structure / formatting issue with my xml or rad tree view context menu doesn't support multi-levels.

DropDownList as TemplateColumn filter

Hi,

I'm trying to implement a DropDownList as a filter for one of my TemplateColumns I'm not quite there yet.
I want the DropDownList to automatically filter my list whenever I change the value of the DropDownList. Are there any code examples covering this? AutoPostBack whenever I change the selected item in it.

Basically... this is what I want to achieve:

Filtering template columns

...but I can't seem to find the code for how to do it. Please help!

[Solved] Wrong key value bound to SelectedValue via Eval()

There is a RadGrid, which is used to show and edit XML-data in a grid form. And the same XML-data can be edited manually.

There is a ComboBox on the RadGrid’s edit template. It is used to select a value from dictionary (a database table of key –value pairs ).

ComboBox is bound to a field in the grid’s datasource:

<telerik:RadComboBox ID="ddProductName" runat="server" DataSourceID="dsProducts" DataTextField="Name" DataValueField="ProductID" SelectedValue='<%# Eval("ProductID") %>' />

The problem is, that since grid’s underlying XML is manually editable, Eval() function may return invalid key values. That is, a value that is not present in the dictionary table. In such cases, the above binding to SelectedValue attribute fails, and the whole page crashes.

What do I do to overcome this problem?
