I created a gauge and set the pointer value when the users saves information.  For some reason, when the page posts back, the gauge loses it's original formatting and goes to a default.  Does anyone know why it does this?

I do not set formatting in anyway in the code behind.  Just the pointer value.

radGuage.Pointer.Value =

Convert.ToDecimal(7.5);

I'm not sure if this is a bug or if this is the way it's supposed to be, but if you set the selected index, then change the selected value of a combobox, the combobox does not select that value, but instead changes the value of the currently selected index. I would think changing the selected value would have the combobox select the item with that value instead of changing the value of the currently selected item. I can also see how it might go the other way so you can change the value of the selected item, but it seems more useful if the combobox actually selected the value you set in selected value. Or did i just do something wrong?

I guess here's my specific question, I have two radcombobox's. when the page loads, i first set the selected index to 0, then check to see if i need to select a specific item in the lists. if i do, i set the selected value of the radcombobox's to the value of that item. however, every time in the codebehind when i try to get the value of the selected item, it always gives me the value of the item at 0 (unless i set the selected value, which it will give me that value instead, even if i haven't changed the selected item).

anyway, if that makes any sense, i actually fixed the problem by not setting the selected index at all (since i was setting it to 0 anyway).

update: nope, there's still a problem. setting the selected value does not show as the selected item in the combobox, although i am now getting the correct selected value in the code behind, when i refresh the window, the "selected item" is the first item in the list. but if i pull down, it shows the correct selected item highlighted

update 2: sorry, the problem was because EnableLoadOnDemand was set to true, now it works fine (stupid... i've been trying to figure this out the last day and a half, and now that i decide to register to this site to post this problem, i fix it before i even get a response, haha)

Hello,

I am quiet confused with saving the dock state in cookie. I just need the C# code to save the dock state in the cookie and I want it to be persisted for a particular time duration.

Please help with code,
JC.

My problem is on the design of radAlert

See the picture attached please.

As you can see there are another two extra buttons behind the normal ones, does someone knows why is this happening? please.

The radAlert from the picture happens when I click a buttonColumn from a RadGrid, see the code.


Thanks

We have two RadGrids sitting side by side in a table, with a RadFilter for each. The RadFilters start out invisible, and are shown by a button on the RadToolbar inside the command templates of their respective grids.  The two grids have set widths, which allow them to fit side by side on the screen. However, when you display the RadFilter, it creates extra width on both sides of the RadToolbar/command template of the associated RadGrid, pushing them out of position. Any ideas why or what to do about it?

The two grids appear on the second RadPageView of a RadMultiePage control.

The relevant code:

Hi,

I am using a asp.net TextBox control inside GridTemplateColumn and OnTextChanged event capuring the text entered by user.
save in memory and bind it back to the RadGrid onItemDataBound.

But after the Grid binds and shows up on screen. I cannot type in textbox control of any row and cannot type in the filter boxes, Radgrid is freezing.

It works after I click the mouse outside the grid and click on filter box or grid template textbox.

Appreciate your quick response on this.

I recently created a custom drop down filter for use in a RadGrid.  I followed the example from these two links:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx
http://www.telerik.com/help/aspnet/grid/grdfilteringwithdropdownlist.html

The grid shows a list of sites.  The drop down displays a list of statuses that can pertain to requests belonging to the site.  See attached screen shot. The column displays a count showing how many of that site's requests have the selected status. 

The grid has an ExportToExcel button.  When clicking that button, the custom control throws the following exception:
 

2013-04-26 10:01:37.923,0000000F,OPSWeb,Unhandled Application Exception [Page Info: /OPSWeb/OPSMain.aspx],Error,Unable to cast object of type 'Telerik.Web.UI.CompressedPageState' to type 'System.Collections.IDictionary'.

10:21

The error occurs in this method on the last line where it adds the combox to the list of controls in the cell..  

        protected override void SetupFilterControls(TableCell cell)
        {
            rcBox = new RadComboBox();
            rcBox.ID = ID;
            rcBox.AutoPostBack = true;
            rcBox.Width = FilterControlWidth;
            rcBox.SelectedIndexChanged += rcBox_SelectedIndexChanged;
            rcBox.DataSource = StatusList;
            cell.Controls.Add(rcBox);
        }
How do I get the export to work?  Why is this causing the export to fail?

Thank you.

I'm having an issue where on slower servers the loading panel seems to stay visible and keeps spinning while also locking up the rest of the web functionality.

Here's how I reproduce it:
1. Click on folder and let it finish loading contents
2. Click on another folder with a lot of items and before it finishes loading, click back on the first folder.

The loading panel just spins and spins thus making the application useless.

The way it's setup is:
1. Folder Tree is in a Web User Control (.ascx)
2. Clicking a folder in the tree causes the correct grid control, also a Web User Control (.ascx), to load inside of the control with the tree

So 1 .ascx is calling another based on the selected tree node.

Hi,
 Is there a way to raise an event after the RadAjaxManager control finishes processing the response from the server and updates all the controls upon an ajax call?
I have a asp:Hidden field whose value is being set by an ajax call. I want to be able to retrieve the value *after* it is set but there seems to be no way of doing that.

I recently moved the RadAjax control into my master page and now we're noticing a few pages where you previously were able to just hit enter to cause a postback no longer work when Ajax is enabled. Is there some setting to restore the previous behavior or do I have to now write some Javascript code to re-enable this functionality?
