Hello I need to programmatically change the colors of a cell specified by its index , i.e. not the selected cell.
I know that the colors can/must be set on the cellelement but I have not found how to get the cellelement of a cell by it's index (or column name) in the currentrow
e.currentrow(7).cellelement does not exists
and I have tried e.CurrentRow.Cells(7).style.BackColor=Color.Blue but it has no effects
Thanks in advance

I'm trying to add a checkbox to all column headers of a GridView, however I cannot see an easy way to accomplish it. Basically, I have a dynamically generated set of columns (which each can contain a different editor). I want a checkbox in the header cell which will allow me to enable/disable that column, however I cannot see a way to do it (I basically want to replicate the 'EnableHeaderCheckBox' functionality of the GridViewCheckBoxColumn, except on all columns regardless of data type). Can anybody offer any advice on how this can be acheived?

is it possible to drop a hyperlink object - as a custom cell, no doubt - into a virtual grid
I downloaded the example from another post in this forum but it was for a checkbox
I found a HyperlinkElement but it is calling for the specific row and column before instantiating
any assistance is greatly appreciated

Hello,
i am using the version 2009.1.9.414. and have great problems with the RadMultiColumnComboBox.
I have a ComboBox bound to a DataTable and now i want to select a Row in the ComboBox. In all other
ComboBoxes i know i would just set the SelectedValue of the ComboBox. My expectation is that the
correct row is selected and the Text of the ComboBox show the value of the DisplayMember of the Selected Row.
When i set the SelectedValue in the Telerik RadMultiColumnComboBox i get the follwoing result.
The Cell which will be found by the current Selected Row and the valuemember will be changed by the passed SelectValue.
This seems to be a bug and not a feature or a user error. Is there any workaround or is it possible to get a patch.
It is urgent because i am using telerik in a huge Project and am at the beginning time enough to change to Componentart or
Infragistics. I want to continue with Telerik so please help me.
Best regards
Stefan

Hello,
I've tried to find some info on this but I'm not sure what the problem really is. Overall I have a master/detail record situation.
I have a datasource bound to a RadGrid and to form items in a "detail" view above the grid. When I click a row the form items in the detail view update with the current record data. Works great, drop down's and all. However, the RadDateTime picker has me puzzled. It updates fine until it hits a record with a null value for the date. Rather than going blank it holds the last date that it received. I expected it to go blank on a null value. The datepicker supports a 'work order closed' field and will remain null until some point in the future.
Is there something i'm missing? or am I going against best practice and there is a better way?
Thanks,
Dean.

I am using the Excel-like filtering in my Winforms application and I have a few GridViewComboBoxColumns that have their datasources set from stored procedures programatically instead of from the database table that I am using for the datasource for the rest of the columns. Because of this, the filters are not automatically filling in the options for these columns like they do for the columns that use the main datasource. I have used the technique described here: https://www.telerik.com/forums/custom-gridview-filter-popup to add custom options to the filters where needed, but once selected and OK is clicked, nothing happens. When I add a break point in the FilterChanging event, I see that the column has been selected as a filter source based on the Property Name, but there is no value and no expression in the filter. Is there something I have to do to format the values added to the DistinctListValues so that they pass a value and expression?

I am working on rewriting our grid reporting system using the Telerik GridView. I have run into one thing I have no been able to do. When I group a report, I need to show a summary row for all group levels. I have attached an example of what I need to do. In it I am grouping on two columns: View & User Id. I show a summary row for each user (pink) and then another summary row for each view (blue).
I have tried to do the same thing with the gridview but i have only been able to show a summary row for the lowest level group.
Does any one have an suggestions on how to do this?
