Hi Telerik team,

I'm using Radgrid to build a tree structure with source of objects with parent and child relationship, 
and the configuration of the grid as below:


Everything works fine until when one of the node is expanded to more that 1 level, and refresh the page (based on some criteria so that the data source now has changed), the following error appears:

Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex

Some additional info on the error:

Source	Telerik.Web.UI
Function	Telerik.Web.UI.GridDataItem get_Item(System.String)
Stack	Telerik.Web.UI.GridDataItemCollection.get_Item(String hierarchicalIndex) Telerik.Web.UI.RadGrid.LoadClientState(Dictionary`2 clientState)  System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

myGrid_ClientState

{"selectedIndexes":[],"reorderedColumns":[],"expandedItems":["1","1","0","0","1","1","0","0","1","1","0","0","0:0_10","0"],"expandedGroupItems":[],"expandedFilterItems":[],"deletedItems":[],"hidedColumns":[],"showedColumns":[],"popUpLocations":{},"draggedItemsIndexes":[]}

Apparently the problem is on client state data "expandedItems", i guess it is trying to restore the expanded items on the new data source (which has been changed and the expanded levels in client data may not be valid anymore).

I'm not quite sure about my observation, but i've tried to override the LoadClientState function in my custom grid:


It does the trick and the page is successfully refreshed no matter how many level of nodes i expanded before.
However i would like to know is there any better solution for this, and why does this happen?

Thanks.







Hi,

I'm working on a project which uses the RadGrid from the classic controls.

Basically, the scenario is this. When the user clicks on an edit button for a row of the RadGrid, the panel which contains the RadGird is made invisible, and another panel with an assortment of textboxes and comboboxes is made visible with details of that grid row item populating thos controls. There is also a delete button on that panel, which delete that item in the database when clicked.

The problem arises when the grid is reloaded after that delete. Following the delete button being clicked, the grid's panel is made visible again and the grid is rebound. If I then click on one of the edit buttons for a row in the grid, the following error is thrown:

Server Error in '/' Application.

JavaScript runtime error: Unable to get property 'id' of undefined or null reference

 

 

I'd like to configure RadGrid as follows:

- if there are no records to display, the grid should display only the header-row and maybe "no records to display" . Consuming no other space.

-if there are records to display, just show all records.

No fixed heiht, no paging.

Is this possible with RadGrid ??

Thanks for any help.

I want to download EXE file on page load event and show real time download progress bar. After successful download, I want to execute EXE file to install on client machine.

How can I do this using RadProgressBar & RadProcessArea control??

Do any one have sample source code of this??

Please at-least take a look of my requirement, I'm researching on it since last week.

We are using Telerik Grid control in our application.
The Grid is getting constructed dynamically, i.e the columns to be shown in the grid is dynamic so we have created custom ItemTemplate and CustomFilterTemplate to implement this.
We have also implemented Column filtering in the Grid with combo box option.
Now, we need to make the filtering to have multiselect option. i.e. the Filter dropdown will show check box items so that user can choose multiple items to filter the Grid.
Could you please assist in this regard.
Attached file contains the screen shot of what we are trying to achieve.

Appreciate your assitance here.
