Hello,

I would like to click on a column in the grid with data and popup a menu to do something with that column of data. To do this do I have to click on a cell with data? Or can it be done with the header? I have the sort turned on for when they click a column header so I guess they need to click on any cell of data right? There is no particular row of data being used. The routines are going to use all of the data in the column. Also, what is the best way to show a menu? I would prefer the menu be near where I clicked. Is that possible for asp.net?

Thanks,

Warren

Just starting with RadGrid control.  Adding and configuring the basic for the grid was easy.  Had problems with getting the column to set to a specific width, but fix that issue with TableLayout attribute to "Fixed" instead of "Auto".  The problem I'm having now is the Filter controls are too wide.  So I tried to used the "FilterControlWidth" attribute for the column, but it's not working.  What am I missing?  See code below.  TIA, Gary

Hi, I'm having 2 radgrids (rgRole and rgRecei) in batch edit mode on same page.I'm using 1 html button to call OnBatchEditCommand from outside to save it. But my problem is that it can call only 1 of second radgrid and dismiss the first one. 

function SaveRg() {
            $find('rgRole').get_batchEditingManager().saveChanges('rgRole_ctl00')
            $find('rgRecei').get_batchEditingManager().saveChanges('rgRecei_ctl00');
            return false;
        }

So how do i get NewValues of radgrid in code behind in another function like 

protected void getRadGridNewValues(){

 // get newValue of rgRole here

// get newValue of rgRecei here

}

Any help appreciated,
Thanks,

1. RadGrid in batch mode doesn't serialize its underlying data source items to the client to be able to manipulate them easily there. Although GridTableView has a dataItems collection (whose name seemed attractive to me), the collection in fact doesn't hold the data records (they're set to null). In fact, the grid uses the DOM as the store of data which made the code complicated (I mean Telerik's code and mine), made the grid hard to extend and manipulate, and introduced problems like this one.
2. Based on point 1, in which I mentioned that the grid is hard to extend, I'll provide an example: My management asked me to create computed columns and aggregates that are updated while on batch mode. Currently, the available computed columns and aggregates don't work while on batch mode, so I had to write the feature myself. I thought that the task is easy, and will be just a call to reduce on the dataItems array, but it turned out that dataItems doesn't hold the data (maybe this collection is used in other modes. When binding to a data service for example, but I'm not sure), and I had to use some combination of getCellValue and getCellByColumnUniqueName and take care of that these functions read the values from the DOM, so when a row is open for editing it won't be involved in the aggregation until it's closed. When I wanted to write code to recompute the aggregates when a row is deleted, I found that there's no "row deleted" event! The grid has a rowDeleted event but it's not triggered on batch mode. It tried the disposing event on data rows, but it's not reliable, because disposing is different than deletion, and I found my code called unexpectedly. To resolve the issue, I created a dummy rowDeleted event that I call by my code when the user deletes a row, and also consider using something fancy like DOM mutation observers to track row deletions. I'm keen on this because I have some other features that requires to be notified by row deletions.
3. As clear in point 2, the API is not rich, and I got the impression that the batch mode feature was half baked. Many times, I find myself in need to do direct DOM manipulations to achieve what I thought should be part of the API of any grid.
4. Based on point 1, the grid doesn't participate in ASP.Net post back operations because its data is in the DOM, not in a structure that can be serialized to a hidden field so that the data is not lost when another control causes a post back. Currently, a batch mode grid needs to be the issuer of the post back operation that saves the data. I have to bind my general save button to call batchManager's saveTable method, otherwise the data will be lost.
5. The documentation is not sufficient. It just states some methods (not all) without descriptions of the parameters and examples. I waste long time inspecting the objects using browser developer tools, and read the source code of their methods to understand how everything works.
6. I wonder why Telerik tries to create this whole thing from scratch. Why not use an MV* framework like Knockout or Angular to create a functionality like batch mode editing, in the same way that Telerik currently use jQuery? Using such a popular and powerful framework will make the component powerful, cleaner, and easier to extend, which will benefit you and us.

Maybe there are other issues that I wanted to write about, but these are on the top of my mind now.
I know that batch mode is a new feature that was added to the current release, but I found it lacking some expected basic behaviours.
I hope it will become better and better in future releases.

I am working on asp.net ajax gird. Is it possible to remove this blue border of selected grid? This is very annoying me. 

http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/simple-vs-advanced/defaultcs.aspx

I have tried a few things but I am unable to get the background color to set on a rad ddl.  Here is the code I have that doesn't work:

Method 1

If (dr("ACTIVE")) = 0 Then
   ddlOperator.Items(ddlOperator.Items.Count - 1).Attributes.Add("style", "BACKGROUND-COLOR: Red")
End If

Method 2

Dim itemData As New DropDownListItem
itemData.Text = dr("NAME").ToString
itemData.Value = dr("BADGE").ToString

If (dr("ACTIVE")) = 0 Then
     itemData.Attributes.Add("style", "background-color: red")

end if

I see that you can enable Smooth Streaming for the Silverlight version.  Can you enable Smooth Streaming for the ASP.NET AJAX version of RadMediaPlayer?

Thank You!

I updated to the latest release 2015.1.401.45 and the ClientExportManager seems to not work since the update. Embedded scripts are disabled for the whole application and I'm bundling the RadClientExportManager.js along with scripts of other controls. I'm getting an Javascript error saying "Uncaught TypeError: Cannot read property 'drawing' of undefined." I don't see any documentation on Disable Embedded Scripts regarding the script files required for the client export manager. The export used to work before the update to latest version. I also use some controls from the Kendo UI Core framework, but I don't think that it has affected it because the export was working along with the Kendo controls before the update of ASP.NET Ajax controls.

Any ideas why the export might not be working?

 Following is the order in which the scripts are bundled.
