Is there a way to Client side filter a grid on multiple columns? As an example, say I have two columns; Title & Description. If I have a textbox where someone can enter a filter term I want to be able to use that serch term on both columns in an OR fashion to accomplish the following

search where title OR description contains search_term 

I see that the GridTableView has a filter function but it appears to only filter a single column.

I have a TreeView that can add nodes dynamically in the client.  After you edit the name of the newly added node it uses ajax to go back to the server to update the database with the new node.

When I run this ASCX on it's own page it runs fine.  However, when I embed this ASCX as content within a tab pane the NodeEdit event stops firing after you edit a newly added node.  It still runs, though, when editing an already-existing node.

Any initial thoughts?  I'm not sure how to pull this out and do a simple repro.  My guess is it won't repro when I dumb down the code.

Thanks,
Kevin

Hi,
I'm trying to add a custom filter to grid using js, like this:
tableView.get_filterExpressions().clear();
tableView.get_filterExpressions().add("ContributionID='" + $get('cContributionID').value + "'");

And this works great. However; if we then filter using the gridcolumn it breaks on:
Telerik.Web.UI.GridFilterExpressions.prototype={find:function(_3e8){
for(var i=0,_3ea=this.get_count();i<_3ea;i++){
var item=this.getItem(i);
if(item.get_columnUniqueName()==_3e8){
return item;
}

Because item is just the filterstring.
I've read http://www.telerik.com/help/aspnet-ajax/grid_filter.html , but that requires that the filtered field is in the grid.

Please advice.

The message is Sys.ArgumentOutOfRangeException: Value must be an integer
Parameter name: x
Actual value was NaN

the page has the splitter, when I click to make it slide out, I get this error.
Please help, thanks.

Hi,

I'm creating a grid dynammically on Page_Init event and using a placeholder declared in my html code. When the page load first time, the grid, the columns, the datasource are created perfectally. When I do a new ajax request (like perfoming a filter), the grid is created like expected on Page_Init (defining all structure like described in telerik online demos), but when the DetailTableDataBind event is called the grid comes with its structure changed. Example, first time the page inits I create a grid with the following structure (on Page_init event):

- MasterTableView
---- DetailtTable 1
-------- DetailTable 1.1
-------- DetailTable 1.2
-------- DetailTable 1.3

After performing a filter (the second load), the grid must be created like this:

- MasterTableView
---- DetailtTable 1
-------- DetailTable 1.1

I follow the code in debug and it is created ok. But when the code enter in DetailTableDataBind event, the grid changed its structure and back to the first structure:

- MasterTableView
---- DetailtTable 1
-------- DetailTable 1.1
-------- DetailTable 1.2
-------- DetailTable 1.3

The instance of the grid is the same (before and after the the DetailTableDataBind event). In don't know why it is ignoring my modifications on the grid structure at Page_Init event. Another problem is when calling the DetailTableDataBind event the Name property is empty even when I set its value (after the first page request).

Thanks.

Hi,

 I've a question regarding radajaxpanel and the ajaxmanager. I've used the telerik example RadScheduler with tooltip. I've extended the tooltip with a button. The ClickEvent is implemenet in the main page (code behind - used a deligate in the tooltip control). The Button works fine, but after executing the onclick event I like to update my rategrid1. It works with an updatepanel if I use UpdatePanel2.Update(). But if i use radajaxpanel the rategrid1 doesn't get updated even on rategrid1.rebind(). Also the Button on the bottom of the page, which is enabled=false should be updated. I guess I've to use the ajax manager, but I'm not sure how this works. Maybe you can tell me how to manage the updates.

Here is my new code again:




Thanks

Hi,

Hi,
I'm using a RadGrid inside a RadWindow (as a popup), to allow the user select a row that will be added on the main page.
I want to get the Key of the selected row and pass it to the main page, the code of the page that loads into RadWindow is:



This code work fine for IE7, however, the event doesn't get fired in Firefox3 (I tried putting a breakpoint on the function OnClientRowSelected(sender, eventArgs) (line 20) and Firefox never reaches it.

I would appreciate any help on this matter,

Regards,

Hi Telerik Team,

We have implemented the RadGrid header localization using Grid ItemCreated event(as per mentioned in your help documentation).But here we are facing major performance issues;reason being during binding of the Grid for every record, Grid Item event is getting invoked, so calling of this event for every record is very time consuming.

We are looking for an event where we can localize grid header at once only other than Item_Created or Column_Created Event to regain performance of the page.

Thanks,
Rajesh

Ever time I try to install the RadControls I get the following error:
"Another installation is in progress. You must comßplete that installation before continue this one".

This appears also after a complete reboot.
How can I discover the process which is causing this error?

Thank you,
Reinhold
