Hi I use this example http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx but when I add my control:

<telerik:RadPageView runat="server" ID="RadPageView2">
<uc2:uc ID="ucmy" RowID='<%#Eval("id") %>' runat="server" />
</telerik:RadPageView>
In information about client I have always get information about the last customer in RadGrid in current page.

Please help...

I get following ERROR
------------------------------------------------------------------------------------------------------------------------------------------------------------------
Microsoft JScript runtime error: Unexpected ajax response was received from the server.
This may be caused by one of the following reasons:

 - Server.Transfer.
 - Custom http handler.
- Incorrect loading of an "Ajaxified" user control.

Verify that you don't get a server-side exception or any other undesired behavior, by setting the EnableAJAX property to false.

I m getting this issue but at only site but not the other. same code i deployed on two different server, at 1 site i get this error but on other 1 i don't. its quite weird for me.

actually my this site has this issue
http://beta.texasdrivingexperience.com/CatalogofProducts/tabid/66/Default.aspx
when you click on Details button

but at this site there is no issue
http://texasdriving.premierwebplatform.com/CatalogofProducts/tabid/66/Default.aspx

code and web.config settings are the same.


but the point, which i m not getting is how could server time out within few seconds :-S

what should i do? if i set Response.RedirectLocation = Request.Url.ToString(); then i think it would redirect to login page rather giving error but actual desired operation won't be performed...

Hi,

I've a radgrid with 2 columns - gridboundcolumn and other greidtemplate column with a dropdownlist in it.

For the dropdownlist, I'm binding the data in item databound.

These 2 columns have been created in ascx like:

 
   <Columns>
                                              <telerik:GridBoundColumn HeaderText ="Search Criteria" DataField="" UniqueName="SearchCriteria" ReadOnly="true">
                                              </telerik:GridBoundColumn>
                                                <telerik:GridTemplateColumn HeaderText="Mapped Tag" UniqueName ="MappedTag">
                                                   <ItemTemplate>
                                                      <asp:DropDownList ID="m_radMappedTagCombo" runat="server" Width="100%"></asp:DropDownList>
                                                  
                                                  </ItemTemplate>
                                                </telerik:GridTemplateColumn>
                                             </Columns>

how'll i access my gridboundcolumn in codebehind.

I need to bind some data to the grid bound column??

in cs:

List<string> strList = new List<string(){"aaa","ddd","cc"};

I need to bind strlist to my gridboundcolumn(uniquename for it is "temp").
so, how do i bind gridboundcolumn to strlist in my radgrid.

Note: i've declared my columns in .ascx

Thanks,
ZR

Hi,

I have an older web application using Telerik.WebControls namespace and *.NET2 assemblies. Where can I find the documentation on how to perform an upgrade of this kind of application to the latest version of Telerik controls? I tried copying the new Telerik.Web.UI.dll, updating web.config and changing all references of Telerik.WebControls to Telerik.Web.UI namespace but it's not working. Thanks for your help,

Marc

Hi,

I have 4 sliders within a RadPanelItem which is initially set to collapsed. when ever I expand it the 

OnValueChanged event fires for each of the sliders. is there any way for me to disable this. it seems that this event gets fired before the item click event of the radPanel if it was the other way around i could simply check for this and stop my other events.

Is there anything I can do or any guidance you can offer for this.

Thanks in advance.

Paddy

has anyone had problems dragging components onto webforms with the Q3 2008 update ?
When I try to do this in code view I get an error  'The operation could not be completed'
in code view, nothing happens at all !

I am using the Telerik Skin now in 2008.03.1105.35 realease in my grid along with the skin Telerik.  The problem I have is that I like most of the skin, I just want to change the SelectedItemStyle-BackColor="#efefef" but it still shows the green selected row.  How can I override the color for the selected row in the skin?

I have the following RaGrid, which displays the CommanItems "Add New Record" and "Refresh" in the Grid at TopAndBottom:
 

 

<MasterTableView Width="98%" ShowFooter="True" CommandItemDisplay="TopAndBottom">

<CommandItemTemplate>

<asp:LinkButton ID="btnAddNewRecord" runat="server" CommandName="AddNewRecord" Style="vertical-align: bottom">

<asp:Image ID="imgAdd" runat="server" ImageUrl="~/App_ThemesCustom/images/AddRecord.gif" />

&nbsp;&nbsp;Add  New Record

</asp:LinkButton> &nbsp;&nbsp;

<asp:LinkButton ID="btnRefresh" runat="server" CommandName="Refresh" Style="vertical-align: bottom">

<asp:Image ID="imgRefresh" runat="server" ImageUrl="~/App_ThemesCustom/images/Refresh.gif" /> &nbsp;Refresh

</asp:LinkButton>

</CommandItemTemplate>

Under specific curcimstances I'd like to hide the "Add New Record" LinkButton and tried to do that on DataBound:
 

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if(e.Item is GridCommandItem)

{

if (!UserHasEditAccess())

{

this.ParentPage.FindControlRecursive(this, "btnAddNewRecord").Visible = false;

}

}

}

 

This code works to a degree. It hides the "Add New Record" button in the "Top" of the grid, but it is still visible on the "Bottom" of the grid.

 

 

Any idea why it's not making it invisible in both the "Top" and the "Bottom"?
