Hey Peeps,

I have a bit of a problem here. I'm trying to populate a RadComboBox using a web service. It's working as expected however, some combo boxes needs to be populated dynamically. Basically I have three combo boxes on a page. The first combo box is populated using the standard ASP SqlDataSource object. The second combo box needs to be populated according to the selection of the first combo box and the third combo box needs to be populated according to the first and second combo box selections. All three combo boxes have their 'CheckBoxes' property set to true (multi selection required across all three combo boxes). I can manage the first two combo boxes using the SqlDataSource however I need to have something like the EnableLoadOnDemand function on the third combo box. If the client has selected ALL categories on the first combo box and ALL categories on the second combo box, then the third combo box will need to be populated with all available products (+/- 123 000 records). In a normal scenario using the SqlDataSource it takes a very long time to populate. I'm trying to find a way that will reduce loading time.

How do you suggest I approach this situation? What I've done so far is to create a web service to handle the data, but I need to specify the categories and sub categories so that the products are filtered correctly. Is there a way to refresh the web service on the combo box so that these items are populated correctly? (calling DataBind() does not affect the combo box when the LoadOnDemand is set to true).

The control:


In the code-behind I'm trying to re-assign the web service settings:


But with the above coding, the page returns an error 'Object reference not set to an instance of an object'. If I remove the coding, then the service populates nothing (because I'm not setting any values into the web service to retrieve categories from). When I don't set the <WebServiceSettings> into the control, and assign it in the code-behind, then the same error is shown.

Any solutions or suggestions will be greatly appreciated!

Hi All,

I am using a RadDataPager to allow my user to page through a series of records.

I am successfully keeping track of every thing.
I should mention I am doing this in code-behind.

I respond to the OnCommand events, get the data, and present each record as they interact with the pagination.

I also want to allow them to add and delete data.

I respond to the TotalRowCount request which seems to get triggered when I issue a FireCommand evet at the DataPager.

Everything works well on the add. The Total row count and current page is updated and the user is positioned on the correct data.

However when I want to remove an entry the current page value in the UI is set to 1.

Now the data being presented is incorrect and if they click Next my code traps because my internal index is set to the wrong value.

I am firing a command with my desired page number but it always sets the DataPage to page 1.

My current work around is to set my internal index to zero.

I'm using a RadGrid with a GridClientSelectColumn and paging is enabled.  I want to perform row deletions in the ItemCommand event handler when a "Delete Checked" linkbutton in the command row is clicked.

I check two rows in the GridClientSelectColumn on the first page, then page forward to 2nd page and check 2 more rows.  When I click the "Delete Checked" linkbutton, the ItemCommand event handler spins through the radgrid.SelectedItems and deletes the two rows checked on the 2nd page, but not the two checked rows on the first page.  I do understand why it works this way.  My question is, what approach should I use to accomplish what I want to do, since this way isnt going to cut it...

Does anyone have a code snippet or example on how to upload an excel file into memory? I don't need to save the file, I just want to process the contents. I'm trying to use the asyncupload component.

Here is the problem:
I have a radgrid with a child grid. For example: Main grid for companies, child grid for employees of the chosen company. I want to add new employees to a company using the "add new record" button in the child grid's head. I made a nested ascx page with some textboxes and a "save" button. I also need the company ID to save the employees data. How can I access the company ID from the nested ascx view?

Sorry for the bad English,

Thanks,
