Hello,
        I am using Telerik control(RadGrid) in sharepoint2007. getting  the Error when i am using GridTemplateColumn

 

        error is <%#Eval("Comments")%> and <%#Bind("Comments")%> is not working in sharepoint2007. 

<telerik:GridTemplateColumn HeaderText="Comments" DataField="Comments" SortExpression="Comments"

 

 

UniqueName="Comments" AllowFiltering="false">

 

 

<ItemTemplate>

 

<%

#Eval("Comments") %>

 

 

</ItemTemplate>

 

 

<EditItemTemplate>

 

 

<telerik:RadTextBox ID="txtComments" Text='<%#Bind("Comments") %>' Visible="true"

 

 

runat="server" TextMode="MultiLine" Width="97%">

 

 

</telerik:RadTextBox>

 

 

</EditItemTemplate>

 

 

</telerik:GridTemplateColumn>

Any idea about this problem?

 

How do I make the button depress on Mousedown?

Let me give an example...

In the Demos page when you click the skin dropdown it shows 3 states, normal, hover, click...so if I choose Sitefinity then try and click the button...I don't see the clicked state.

I'm losing State when using IE8. any ideas?

Hi

I want to customize the DataPager UI. I would like to show a datapager similar to that of PrevNextNumeric pager. But I want to show all buttons (previous, next and numeric) as plain links (Simple anchor tags in html).  Hide the previous link when the current page is fist page also hide the last button when current page is last page.

How can I customize the UI? One option I can think of is using PagerTemplate and writing custom code to implement.

But is there any simple alternative for this? If not can some one provide me with a sample of how it's done u sing pagertemplate.

Note : I'm using custom paging too. But I think it does not make much difference.

I have attached how I want the UI to look like.

Thanks in advance,
Kartheek.

When i deployed the user control and web part in SharePoint 2010, I am able to view the data but i face 2 issues in this.
1. First time, when i select anything in the dropdownlist or select any row in the grid, its not ajaxified but full post back is happening. Second time on wards it works perfectly fine.
2. I want ajax on ddl and grid but when i uncomment the line that is commented above, I am able to select a row in the grid only for the first time. From second time onwards, i am unable to select.

Please do help me resolving this. I am using the trial version of Telerik.Web.UI.dll 2010.2.713.20

Please do send me a sample which does the similar functionality.

Thanks in advance.

I am working with the latest telerik editor (Q3 release). so far every control in my project is upgraded successfully. but in image manage in the editor, the delete button is not visible. I was able to add create directory button from the provider (DBContentProvider) by returning true from CanCreateDirectory property and overloading  the CreateDirectory() method. is there any similar property for adding delete button?

Thanks.

I have downloaded trial version of TELERIK controls for ASP.Net AJAX few days back.
My application uses Callback to load content inside the RadSplitter control.(Please note not AJAX callbacks, simple callbacks)
I have set the RegisterWithScriptManager property of RadSplitter =false, to allow rendering the RadSplitter's  HTML output after  callback.

The RadSplitter gets rendered successfully, but none of the RadSplitter functionality like (resize etc) works  after the callback.
Your forums suggest to manually register the RadSplitter scripts into the RadScriptManager, to get the functionality back.
I have 2 queries-

Query 1- Do I use the below code snippet ?
 Query 2. If so what will I pass to the 4th argument ?- "script".

PLEASE TREAT THIS AS URGENT.
I need to take a business decision for using Telerik controls based on this.  Have already posted similar query earlier, but have received no response so far.
Thanks, Tanima

How to check which columns are grouped ?

Hello,

I was testing out the demo for the GridAttachmentColumn directly from the demo page - http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/gridattachmentcolumn/defaultcs.aspx and while I tried uploading a file from both a Local and Network Drives, I keep getting a 'Sorry couldn't find a page' error.  I have tried in both Internet Explorer 7 and FireFox 3.6.12 browsers. 

Also, I have developed a page using the most current RadControls for ASP.NET AJAX Q3 2010. Although uploading and viewing the file (.XLSX) from a local drive did not have any errors, however viewing the file after uploading from a Network drive produced this error:

Unterminated string passed in. (61): {"ID":30,"ColumnUniqueName":"AttachmentColumn","FileName":"G:

Do you know how I can fix this problem?
