Hi There,

I have a RadCombobox that is placed on a CommandItemTemplate and in my SqlDataSource Selecting event there I need to get the SelectedValue from the RadCombobox. I have tried to use the FindControl function but I can't get it to work so I would be happy if you could tell me how this is done :)

Thanks

Hi

In radgrid i'm rebinding data in edit. so i couldn't maintain its scroll postion.

Even i've set "SaveScrollPosition=true"

NOTE : its working fine when i take off ajax setting to rad grid and Load button. but its not tracking its scroll position while controls where loaded in ajax panel.

Hello everyone,

I created a web user control called MultiSelectDropDown using RadComboBox based on the example Telerik.com provided.
When I drag and drop this control into a web page, It works perfect, My problem is , when the page has 2 or more MultiSelectDropDown ,
Only the one works, for the rest of them, when I click check box items, the text in combo box always empty. I hope some one can help me out.I appreciate it in advanced. Below is code:

Hi!  I have a RadGrid with a MasterTable and a DetailsTable.  The MasterTable has a column in it with the 'expand' button.  However when I click on the 'expand' button nothing happens. 

I've checked to ensure the 'GridRelationFields' have the correct values for the 'DetailKeyField' and the 'MasterKeyField'.  The MasterTable and the DetailsTable both have columns for these values.

Could someone provide suggestions for troubleshooting?  I have this same logic working on another page in our web application, but must be missing something for this particular page.

Thanks!

Hello,

I have a radiobuttonlist and when I select a certain choice it enables a RadDatePicker and a RequiredFieldValidator. So in my code behind I enable and disable my RequiredFieldValidator. I've found that when my RequiredFieldValidator is updated by my RadAjaxManagerProxy it doesn't validate anymore.

Thanks

I've been trying to dynamically bind a list to the data source of a GridDropDownColumn in a detail table. I have manage to get it to mostly work, but it isn't binding the first row's cell. I've been using the code below in various radGrid1 subs, and I keep getting the same results. I believe that I'm binding the data source after the first row is created and bound, but where do i put it so I can bind the data source before the first one.

Thanks for any help.

Hi,

I have been using Menu ASP .NET RadControl from RadMenu.Net2.dll.
That worked fine.

Now, I'm trying to update this control with latest ASP .NET AJAX RadMenu control from Telerik.Web.UI.dll.

The requirements and exceptions came up to me as it will require ScriptManager before RadControl is used in the code and ScriptManager in turn requires Form Tag with RunAt server.

I have done that which lands me with this kind of exception.
System.ArgumentException: Script control 'xnaMenu' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Anybody has faced this similar problem? I do see similar exception reported on RadDock control and Telerik team provided another new dll as temporary solution. So, what was changed in the DLL? I would like to know if I can overcome same thing in my code, or I need new temporary DLL from telerik :)

Thanks,
Chirag

I have seen several posts on this topic, but have not seen a solution that will work yet.  I want to add a linkbutton to my group header that will use data from the group header in the postback.

I have something like the following:

LinkButton lnk = new LinkButton();
lnk.ID = "lnkReservations";
lnk.Text = "View All";
lnk.CommandArgument = (DataRowView)item.DataItem["employer_id"].ToString();
lnk.Command += new CommandEventHandler(lnkReservations_Command);
item.DataCell.Controls.Add(lnk);

I have tried adding to the event handlers for PreRender, ItemCreated, ItemDataBound but have not been successful in any of those attempts in getting the linkbutton to behave correctly.

Is there a simple solution to add a linkbutton to a groupheader that will execute a function based on the data/header where the control sits?  Is there any kind of special column that I can add to turn a header into a linkbutton?

hi,

i created a grid for my project. But now i faced a GridDropDownColumn problem. What i done is i put a DataSourceID="SqlDataSource2"  in a GridDropDownColumn. when page load, i cant get first row data unless i refresh it through refresh button on MasterTableView. then for other record can display normally.

any helps is appreaciated. Thank you.

Best regards,

Hi Telerik Team,

I've implemented the MOSSRadEditor Placeholder for a client who is complaining about the slowness loading the page due to the RadEditor in Edit mode.  There can be as many as 10 placeholders on the page at once and the page loads really slowly as a result.

We want to try ContentAreaMode = 'Div' to see if it offers a speed improvement but we cannot find where to apply this setting.  With the RadEditor it is a simple attribute, but because we are using the MOSSRadEditor placeholder, we cannot set the "ContentAreaMode" property.

I also tried adding: <property name="ContentAreaMode">Div</property> to the config.xml file but this has no effect.

Is this attribute supported with the MOSSRadEditor?  If not, can you suggest things we might be able to do to speed up the loading of the RadEditor in Edit mode?  The client is nearly ready to pull the Editor altogether due to the speed issue.

Thanks
