Hi,

     I am using RadGrid to display items.But for editing of grid data, I am using a webuserControl . The webusercontrol works fine.
But as per the project requiremnt, I have to show the edit form/webusercontrol along with grid data in the bottom half of the page. The web user control would show the edit form for the selected grid item.

Grid page




Any idea?

Thanks,
Rita

Hi,
I've been having issues since i have updated from Q2 2009 to Q3 2009.  Tha major problem at the moment is happening at design time.

When i have a control on an ASPX page, like a panelbar, i select the panelbar in the design view and in the Properties window i select the Items collection option and add in a number of items.  I click on OK and the new items i have entered display in the Design time view fine.  The problem is that if i switch to the Source view, the items are not there.  Nor are the items displayed when i compile and run the application.
However, even after running the page and going back to the design view, the designer shows the items still there, but they still are not in the Source view.

I have found i can force to Source to be updated if i use the Smart tag and change the Skin or edit a template (the Smart tag still shows all the items i add in the template list for editting).

Any ideas?

I have uninstalled all Telerik version and reinstalled from scratch to no avail. 

Thanks

I having problems getting my Master/Detail grids to work. I have a page with two separate grids. Grid1 is the master and uses NeedDataSource to get it's data.   Grid2 is the detail grid and will also use the NeedDataSource to get its data.  Similar to this example:http://demos.telerik.com/aspnet-ajax/grid/examples/programming/selectedvalue/defaultcs.aspx.  However, the example doesn't use NeedDataSource it uses client side declared datasources.

Grid1 (Master) is working fine(Retrieve data / Add/Update/Delete).  But I'm not sure how to connect the Master grid to the Detail.  I have turned on postbackonrowclick in Grid1.   I was thinking I could call Grid2.Rebind() (Detail) in Grid1_NeedDataSource (Master) and pick up the Grid1.SelectedValue (Master's selected value) in Grid2_NeedDataSource (Detail) and pass it to my datalayer and everything will be good.  But this doesn't work. I'm getting an object reference not found on Grid1.SelectedValue on page load.  I'm guessing that's because nothing is selected on page load. ( I figured if nothing was selected it would return 0).   What's the best way to get this to work??

Hello,

I am using a grid control with a user control for editing the data. The Grid also allows multi editing and is using Paging.

I want to automatically save any changes that are in my edit control when someone navigates off the page or causes a postback. Here is the code I am using to gain access to my control for saving, but it always returns “Nothing.”

Is there something I’m missing?

I'm using RadGrid Ajax Q3 2009.  I can't believe I'm having trouble with something so simple.  All I want to do is retrieve a value of a non-editable cell for a row in edit mode. 

Using the Update or Item Command event to get the value

GridDataItem

 

dataitem = e.Item as GridDataItem;

 

string mycell = dataitem["MyColumn"].Text;

always gives mycell with a value of  " "

What the hey am I doing wrong??

Hi Team,

Hi,

I'm currently building a controls library demo site for my company.  I really like the silverlight demo that Telerik has.  I have already implemented the transition effects.  What i'm curious about is the background image for the overall page.  It appears to be an image that auto scales with the browser window.  Can you tell me what that is?  Are you building an image using xaml somehow or is that one big image and you have figured out a way to have it scale?

Thanks

I'm using a RadTabStrip that contains RadTabs with Silverlight grids (RadGridView). The grids are configured with validators. On postback while attempting to save to the database I'm having the following issue: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus. The Java script debugger breaks on the d.focus() call in the script segment below. This segement is from RadInputControl.js from Telerik.Web.UI. d is the Silverlight grid and its offsetWidth is 0 at this point. Also, this grid is not on the current visible tab. Let me know if you need more information.

Thanks, Mike Fernandez
