CustomDBProvider with CustomContentProvider

I'm using the documentation and online source to try and build my own CustomDBProvider and CustomContentProvider. I'm running into some issues and was hoping to get some help. My goal is to have some "top-level" folders which will dynamically query a third-party system (via a COM SDK) and display folders and/or documents. One of the top-level folders might be called "My Documents" and should only show documents. Another might be called "My folders" and could show folders (which might in-turn have sub-folders). Another example would be "My Labels" which might contain either documents or folders. I"m using some static pathing so that I know how to execute different commands in the third party system. I can't use DataTables because I need to load the information on-demand.

For now I just want things to be displayed in the UI. I've made everything read-only. I'm not worried about uploading at this point.

I've gotten the "My Documents" to work perfectly. But I can't get "My Containers" to work. It executes the code and loads the directories into the function, but nothing gets displayed. Any help would be greatly appreciated!

Missing icon when commandname = Delete

Hi All

I've just noticed this , (been messing around with the app and didn't notice when this happened)
I have RagGrids with a COmmandName = Delete. This I think is a build in command.

The icon doesn't show for this. If I change the command name to a diffferent name other than the built in one (DeleteZ) the icon shows.

Also all the icons have disappeared from the reporting module too.

Need help with Hierachy grid expanding to nested view data

Hi,

I am trying to get the telerik hierachy grid to work. I got the grid row to show up when the grid is loaded. When I click on the arrow to expand the first row, the row expands. I see the two tab page and the first tab grid data is loaded. However when I click on the 2nd tab, nothing happens. when I clicked the 2nd or 3rd row, it is not expand. It just display a blank line.

Any help is greatly appreciated.

RadGrid Dynamic DetailTables

Hello,

I want to know if there is any way I can dynamically add a Detail Table between a Rad Grid and another Detail Table.
The structure would be the following:

Before addition:
<RadGrid>
<DetailTable ID="1">
</DetailTable>
</RadGrid>

After addition:
<RadGrid>
<DetailTable ID="2">
<DetailTable ID="1">
</DetailTable>
</DetailTable>
</RadGrid>

The Rad Grid and the detail tables feed from their own objectdatasource.

Thanks in advance.

keep list of files

hi

i would keep the list of files after a postback like do the postbacktrigger property but i need it for validation purpose and so the postback to validate is the same than for upload.

i mean i have a single button to save my form and upload the file in server code i validate my form if there is a problem. i need to show again the form with information about the validation if no problem i save everything.

if i use the postbacktriggers property i don't get the upload event and i absolutely need it.

so i'm looking for away to give or keep the list in client side.

hope it was clear enough :-)

thank you

GroupFooterTemplate issue

Hello all,

I have encountered a problem while using the GroupFooterTemplate in RadGrid. I have implemented a RadGrid using GroupFooterTemplate according the documentation that I have found at your web site. Here is the link to the documentation:
Group Header and Footer Templates

In the GroupFooterTemplate, I used several <td></td> together with labels to show the footer items. I have to use GroupFooterTemplate because a checkbox must be displayed in one of the footer columns.

The issue occured, when I used Aggregate="Custom" as follows
<telerik:GridBoundColumn UniqueName="OrderNo" DataField="OrderNo" HeaderText="Order No." Aggregate="Custom" />

The error message that I got is as follows:

An entry with the same key already exists.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: An entry with the same key already exists.

Source Error:

If I used Aggregate="Sum" or Aggregate="Count" instead of Aggregate="Custom" , the web application could run without error. Could you please tell me how to use aggregate custom correctly while using the GroupFooterTemplate?

Many thanks in advance!
