Hi,
I have a similar problem as mentioned in the following thread:
http://www.telerik.com/community/forums/aspnet-ajax/grid/issue-with-filtering-on-multiple-columns-when-mastertableview-enablecolumnsviewstate-false.aspx
I need to have the EnableColumnsViewState disabled and make the grid to be filtered by two columns. At the end of the thread mentioned it is said to create the FilterExpression over and over again. I tried to do that by saving the CurrentFilterValue and the CurrentFilterFunction and using the EvaluateFilterExpression method of the column.
But most of the time when the EvaluateFilterExpression is called it returns string.Empty even after I have reset the CurrentFilterValue and the CurrentFilterFunction of the column.

So my question is if there is another way to evaluate the FilterExpression. Or are there other properties to be set to evaluate a column's FilterExpression correctly?

Best regards

Ferdinand

I have a RadGrid with child DetailsTables bound to Entity Data sources. This all works.

How do I add dynamically add a column to, say, a second-level Data Table, which gets the "MAX" value for the third-level Data Table.

For example:

 - Job Type 
  - Job  <--- [I need to show the Wage for the current ​Effective Date here]
     - Effective Date(s) + Wage

I figure I'll need to do this dynamically, as it's too tricky to determine the current effective date, e.g. (now <= Effective Date).First() . 

Anyway, not sure if I do this in ItemCreated for the OwnerTableView of the DetailsTable or in a higher-up event.

Thanks.

I add
<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload"></telerik:RadAsyncUpload>
to an empty .aspx web page
When selecting any file type it always shows the red Circle
I tried every possible properties of  RadAsyncUpload  I know such as MaxFileSize
I guess it may be a network issue , since we have a proxy in our network.
Any one have and Idea about this?

My combobox shows a background color and I am not able to figure out how to show a white background.
I also tried building a new style using the stylebuilder. It showed a white background when I was building it but wehn I used it in my website it came up with a gray background.

I want the combo to look like the first dropdown in the attached image (that is using an asp.net dropdownlist)

We are facing an issue in radgrid batch editing for cell, if you try to enter a 4 digit value for decimal, it adds a comma in the value and gives the following error upon saving changes:

System.Exception: 1,200.00 is not a valid value for Decimal. ---> System.FormatException: Input string was not in a correct format.

Also tested it on rad grid demo site and same issue is there as well:

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultvb.aspx

Please try entering a 4 digit value for column 'UnitPrice', after entering the value it will add a comma and show error on save changes, however the error is different.

Thanks

I have a piechart, binding data from a storedprocedure. I am getting 2 columns  one is Age and BusinessTotal. Based on Age column data, Color should be showed. Please let me know how to accomplish this.

                }              
}
              

Here is my scenario:

I have a RadGrid with RADAjaxManager rights to update itself. In markup, I have some GridTemplateColumns that contain custom buttons. The rest of the columns get populated via AutoGenerateColumns="true" from the NeedsDataSource event of the grid.

I am using the ItemDataBound event of the grid to setup each GridDataItem, setting some buttons' enabled property and some images based on the grid's data. This is working great to load the grid, and it persists after sorting, paging, and filtering.

The problem that I'm running into is when I click one of the custom buttons, it will properly run through the ItemCommand event of the grid, but then the buttons' enabled state and the images that I set are wiped away. Since my code to set these things up is in the grid's ItemDataBound event and that does not fire after the ItemCommand is fired, I'd like to know what event should I be using to set enabled/image URL type properties of the grid cells?

Thanks!

I have a RadDropDownTree control on a page, I can successfully bind data to it [and read back the selected node's value], and I can successfully set the value BACK on loading a form.  However, when I programmatically set the selected node, it doesn't show up on the page.  I have to manually expand the DropDownTree and select the already selected item.

How can I have the DropDownTree ACTUALLY select the node programmatically?

I'm using Telerik ASP.NET AJAX v2014.1403.45

Hi,
I have a simple Grid with a GridDropDownColumn using the default RadCombBox. On Eidt and Insert, I bind the Combo to an XML-based Dictionary inside ItemDataBound. Both functionalities are wroking fine and I can save updated records without problems. However, I keep getting above error every time I attempt to Insert, although the process is working, whether I Cancel or Insert, with the Combo being populated as expected. In other words, the error doesn't affect Insertion but it is annoying to keep showing! How can I eliminate it?


Grid markup:



ItemDataBound (VB):



I thought of handling each process separately, but I will end up with redundant code! 

Many thanks in advance.

I have a page where I show the user 4 columns from an sql query, in a grid.
If they export , we have to include all 15 columns, which leads me to wonder if I could not just create all in the code behind, a new virtual instance of a radgrid, and populate it with my full sql query result set, and then use the exporttoexcel() method call without showing the user the second grid.

Is this possible? If so, what would be the limitations or tips to making sure this works seemless?

Thank you for you help in advance.
