Hi team,

We have grid in windows application and having functionality to remove columns by dragging the column and dropping it outside the grid. now we are migrating the current windows client application to web based solution and we have considered using telerik ajax UI controls for development which has the similar features.. however for drag and drop functionality, RadGrid support only row level. what we need is column level, user should be able to remove the column by  dragging and dropping the column outside..

Regards,

Suruli

Hi there, 

I am trying to change the expand/collapse of the radgrid on the fly. The reason is because I wanna change the icon when I do not have any item on the detail table for the respective Item, working as a visual cue.

Following is my code:

GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
            foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
            {
                foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
                {
                    if (**myBusinessLogic**)
                    {
                        nestedView.ExpandCollapseColumn.ButtonType = GridExpandColumnType.ImageButton;
                        nestedView.ExpandCollapseColumn.ExpandImageUrl = "../Resource/Image/CustomExpand.png";
                        nestedView.ExpandCollapseColumn.CollapseImageUrl = "../Resource/Image/CustomCollapse.png";
                    }
                }
            }

After running this code the icon remains the same. 

Thank you

Hello guys,

I'm having trouble updating textbox "A" thats inside a repeater from a button which gets some textbox "B" from is inside the repeater aswell.

First of all, the content of the textbox "A" is binded with DataBinder.Eval and I'm getting an error "The Controls collection cannot be modified because the control contains code blocks (i.e. <% … %>) " and I found a solution online by wraping the repeater with <telerik:RadCodeBlock runat="server">, is this the correct way of fixing it?

Here is my ajaxManager:

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">   
        <AjaxSettings>  
            <telerik:AjaxSetting AjaxControlID="listaDeElementos"> 
                <UpdatedControls> 
                    <telerik:AjaxUpdatedControl ControlID="listaDeElementos" /> 
                </UpdatedControls> 
            </telerik:AjaxSetting> 
        </AjaxSettings>  
        </telerik:RadAjaxManager> 

After I click the button, changes are actually made in the database but the repeater does not refresh. Nothing happens and I have to reload the page to actually see the changes. Here is my repeater:

    <telerik:RadCodeBlock runat="server" ID="radcode1">
             <asp:Repeater ID="listaDeElementos" runat="server" OnItemCommand="listaDeElementos_ItemCommand" >
             <ItemTemplate> 
                 <asp:TextBox runat="server" ID="txtMostrarComentario" Text='<%# string.Format("{0}", DataBinder.Eval(Container.DataItem, "Comentario")) %>'        enabled="false" TextMode="MultiLine" Width="65%" style="margin-top:10px;resize:none"></asp:TextBox>
                 <asp:TextBox runat="server" ID="txtComentario" Text=""  placeholder="Añadir comentario" TextMode="MultiLine" Width="33%" style="margin-top:10px;resize:none"></asp:TextBox>
                 <asp:Button ID="btnGuardarComentarioYnumeroDeSerie" runat="server" CommandArgument='<%# Eval("Id") %>' CommandName="GuardarComentarioYnumerodeserie"  Text="Guardar" Width="100%" CausesValidation="False" />
                  <br />
                 <hr />
              </ItemTemplate>
            </asp:Repeater>
      </telerik:RadCodeBlock>

So how do I make it update? 

Thanks.

Hi, 

I have used RadListBox control at many places in my project. The issue is intermittent, especially in IE10 and IE11.
The icons(rlbButton) appears blank i.e. without the arrows etc... Please provide a solution or a workaround for the same.
Please find attached the snapshot.

Thanks

I'm trying to have my controls get updated when the SkinChooser changes value to some other Skin (I'm using the embedded DLL skins provided).

in my code behind: 

fairly basic stuff, but my controls don't update with the newly selected skin ... what am I missing?

Cheers, Rob.

Hi, I'm using a treeview control on my application, and in my Dev, Test and UAT environments, I'm seeing the arrows for the expand/collapse icons.  However, on my Prod environment, which theoretically is the same as my UAT environment, I see the plus/minus signs.

Looking at the css coming down as a WebResource, on UAT, I see:

/* START Telerik.Web.UI.Skins.TreeViewLite.css */

But on the css that comes down from Prod, I see this:

/* START Telerik.Web.UI.Skins.TreeView.css */

I've gone through my code trying to figure out why, can't see anything.  Also, after looking through documentation on this site, I have added the following lines to my web.config, but with no change:

   <appSettings>

      ...
      <add key="Telerik.Web.UI.RenderMode" value="lightweight" />
   </appSettings>

...

   <system.webServer>

...

      <httpProtocol>
        <customHeaders>
          <add name="X-UA-Compatible" value="IE-Edge" />
        </customHeaders>
      </httpProtocol>
   </system.webServer>

Is there any other things I should know about my production environment that might be causing this behavior?

I'm currently using version 2017.1.228.40 of the Telerik assemblies &  running .NET 4.5.1

Thanks,

Phil

Is there any mechanism in the Spreadsheet classes that would allow me to insert or extract an object file from a spreadsheet?  I cannot seem to locate anything on the matter in the API documentation or on the objects when debugging.

Thanks,
