Hello,
I tried to create the columns on the radgrid dynamically on Page_load (I can't create them on page_init)
I followed the instructions on your site but I keep getting the following error after each postback once the grid is created:

[GridException: Cannot find a column with UniqueName 'alert_id']
   Telerik.Web.UI.GridTableView.GetColumn(String columnUniqueName) +102
   Telerik.Web.UI.RadGrid.LoadClientState(Dictionary`2 clientState) +5156
   Telerik.Web.UI.RadCompositeDataBoundControl.LoadPostData(String postDataKey, NameValueCollection postCollection) +109
   Telerik.Web.UI.RadCompositeDataBoundControl.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) +13
   System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +690
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743

I added the bound-columns to the mastertable before I set their properties.

The grid is created once, but each postback throws this error.
The error occures even before "Page_Load" happens.

My main goal is to add a button to the header which will open a custom context menu (so I can't use auto-generate-columns) and still have all the functionalities of group-by/sort/reorder etc. also, the grid's columns should be created dynamically since the datasource is set during run-time and I don't know what are its columns at design time - The grid is inside a RadTabStrip and each tab-click sets a different data source into the grid

I'm looking for a way to change the columns in the Image Manager. I use already the FileBrowser.ascx from the EditorDialogs folder. The problem is that there is only a ascx page and no code behind were I can change the default behaviour.
In the FileBrowser.ascx it looks like this (default):

The default columns are now Filename and Size, but I would also like to show the Title field from the Image library.

Is it possible to replace this with a custom class that has the RadFileExplorer as a base class? Or is it possible to change/add columns via JavaScript?

Hi!
When using BinaryImage deployed on IIS with multiple worker processes (Web Garden) image is not always shown.
I assume it depends on that BinaryImage is using cache object and cache objects only lives in one worker process.
Any solution?

I'm a newbie with these Telerik controls.  So, I am not sure where to begin.

Here is the requirements of the page I am trying to build

1.  There is section on the page that prompts the user if they want to "attach" any files to this request.  A request is a single row in the Request database.
2.  So, I was plan on allowing the user to navigate and identify various files that they want to attach to this request.  For each file that they identify, a row is created in table on the screen that contains the path and file name.
3.  When the user submits the request (as in save the request to the database), then I would like to create a ZIP file for all those files listed in the table.  Once the ZIP file is created, then I would like to save that ZIP into the database as a CLOB.

So, which Telerik controls should I use?

Hi,

I'm trying to build a grantt chart with the data shown below using data bind control but when I click on the data tab of the wizard the propert screen just closes.

ProjectName	Project Start Date	Project End Date
CISF	10/12/2008	11/1/2008
Dashboard	10/10/2008	11/1/2008

Can someone help me create a grantt chart with the above data.

This happens when the chart type is set to Grantt but the rest of the chart types work perfectly

Here's the issue:

When I have a RadUpload control on the page and then do any type of Ajax call before a submit, there is repeated calls to Raduploadprogresshandler.ashx until the browser is shut down. This issue was also documented here:

http://www.telerik.com/community/forums/aspnet-ajax/upload/mulitple-requests-to-telerik-raduploadprogresshandler-ashx.aspx 

but, I tried both of those fixes and neither worked completely. Adding:

<add key="AllowCustomProgress" value="false"/> 

to the web.config worked, but only if the RadUpload control did not have a file already selected.

What is the correct way of avoiding this issue?

Thanks!

Hi,

I have a RadSlidingPane that has a top and a bottom RadPane.  The top one has 2 buttons and the bottom one has a user control which contains only a treeview.



As you can see from the attached screen shot, the RadPane doesn't resize when the RadPane expanded.  It will resize when the RadPane is docked.  I looked at the page source and I could see my user control being wrapped with <div> tags that set the width to 22px.  I tried to resize it during OnClientExpanding/OnClientExpanded, but I couldn't make it work.  Could you show me the correct way of resizing the RadPane?

Javascript :


Thank you,

I have a RadGrid that I need to put hyperlinks on the dollar value in a column of the RadGrid that will link to more details and I also need that column to aggregate the sum of each of those dollar amount and put it in the group footer for each group.  Neither the GridHyperLinkColumn or GridTemplateColumn have the Aggregate property like the GridBoundColumn. 

How would I be able to aggregate the values of a GridHyperLinkColumn or GridTemplateColumn so there's a total in the group footer?

Morning All,

I am using a RadTreeList with its height set to 100%, which is working absolutely fine.

Whenever I try and add UseStaticHeaders=true the height shrinks to a very small height and I can only see about 4 records with the rest scrolling.

Am I missing something? I tried no ScrollHeight and a ScrollHeight of 100% and it was exactly the same. I also tried putting the treelist inside a div set to 100% and that didn't work either.

Regards, Paul.

Hi. I have a rad grid with a number of columns, including two date columns. I am using an auto generated pop up form for editing data. On the edit form I would like to make it so that when the user sets a date in the first date field, if the second field is blank the value of the second field is set to one year after the date in the first field. I have tried to add client side and server side code to achieve this but am having no luck getting the right combination of event handlers and control references. Any help would be really appreciated.
