Hello,

First, I wish you a happy new year ! :-)

Secondly, I am trying to include in the code of my RadGrid the filter template which is being shown here :  http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx

But it seems that to fill the DropDown boxes , you are accessing  the database each time by defining SqlDataSource objects (for example SqlDataSource1 in the code sample :



What I want is to have in each dropdown box only the values that really appear into the corresponding RadGrid column (data from RadGrid datasource) and not all the available values from the database. For example, if I only have 3 different records in the grid, I just want to have the three corresponding values in my drop down boxes.

So can an you tell me how to define my DataSource for all DropDonwn boxes to achieve that ?I have been looking at ObjectDataSource but it seems that by using SqlDataSource or ObjectDataSource, il will always have to send an SQL request to the database. That's exactly what I want to avoid, as I already used an SQL request to retrieve the data when populating the RadGrid ...

 Thank you for your help.

Dear,

      I  have used datagird to loading data , When I set up one cloumn with  checkboxSelectColumn and set up "headertext=select all"" ,But  run this page, this grid didn't display headertext,only  a checkbox in head.

     Please help me to tell me how to solve this problem. thanks a lot.

Hi, I was wondering how I could go about the code behind on this. I have my grid which display records and can filter by active, inactive, etc... then when I want to look at further details, the details table does not populate and now I am getting an error on:

If

 

 

e.Item.ItemType = GridItemType.Item OrElse e.Item.ItemType = GridItemType.AlternatingItem Then

 

 

 

 

Dim record As table 1 = e.Item.DataItem<----------

 

that says:

Unable to cast object of type 'xxx.Model.database.table2' to type 'xxx.Model.database.table1' .

what is going on here?

I have radgrid  and placing complete Radgrid  in edit mode.

I have save button in command template.

I need to update the rows when  save button is clicked.

Is there a way to know the list of changed rows on server side so I can issue the update command only to that particualr row. I do not want to issue command for all the rows irrespective  whether it is changed or not.

Thanks

Hi,

I am trying to get a column value of a selected row in the radgrid.
I am using "DataKeyValues" in my C# code to retrieve the value. But it always returns an empty string. When I debug I can see the key but the value for that is empty. 
Following is my code. Please let me know if I am missing something.

Thank you,
Lahiru

I have a .aspx/web form that uses the Rad Decorator.  I am using one of the Responsive frameworks on the page and have constructed a menu using ul/li that will morph into a combo box when the page width decreases past a certain point.  This is all working fine.

I would like to use the RadComboBox for the mobile-sized menu container but I cannot seem to control visibility of the RadComboBox during page size changes using the normal method of doing so from media queries -- see below.


When I try to use the styles, they appear to have no effect whatsoever on the RadComboBox.  I have tried telling the Rad Decorator to ignore SELECT controls to no avail.

Is there a way through the CSS that I can control the visibility of the RadComboBox when the RadDecorator is being used?

Thanks in advance!

We are looking to implement a responsive UI application which allows server-side events (i.e. data, sql, etc.) to be pushed to clients and have the UI refresh but not lose context. For example, we have a prototype working w/INotifyRefresh and a WPF app. However, we would like to explore the idea of doing a web app.

The new ASP.NET version has support for SignalR which allows for server events and data to be pushed to the client. Can we achieve this in ASP.NET or MVC w/out writing a massive amount of code? The application uses listviews w/checkboxes, the underlying data (ids & text) is changed, added or removed while leaving valid, existing checked state.

I have a RadGrid where I am auto generating columns because they can changed depending on the source. And I want to display only certain columns and in a specific order. Its easiest for me to store the columns to display in a comma delimited string. I created the code below to try to do this. However it fails because in the Page_Load method the grid.MasterTableView.Columns is always empty, even though I do a DataBind first. Any idea how I can get this to work?

Thanks,
Jason
