Hello.

I am using Telerik ASP.NET AJAX RadGrid 2010.3.1215.40 in an ASP.NET WebForms application and have the following problem: When I hit the export button of the grid the generated PDF file is displayed with the wrong filename and extension to the user.

The correct filename would be "my-product-list.pdf".

But the filename used is "index.aspx" (the name of the ASP.NET WebForms page).

These are the export settings used on the page:

For some strange reason the problem only happens on our production server. Just like in this case: http://stackoverflow.com/questions/30050996/asp-net-content-disposition-using-wrong-filename-on-production-server (also posted by me)

Could you please help me to find out what causes this behaviour? I am out of ideas.

I noticed in all the current examples for the Diagram Control it only has the rotate button that only rotates 90 degrees instead of letting you manually rotate.  Is it possible to still get the shapes to rotate using the method used here:http://dojo.telerik.com/uZeN  or is this only possible in an older version? 

 Or maybe it would be possible to copy something out of the script files in that example into the current version to get the rotate to work this way?

Thanks.

Hi,

I have a RadComboBox with the checkboxes active. I want to have a postback for the ItemChecked event.

The combobox also is generating a postback on closing of the dropdown which I do not want. How can I prevent this to happen.

I have found a similar thread (http://www.telerik.com/forums/radcombobox-auto-post-back-issue) but the link to the solution presented there does not work anymore.

I am having an issue with following the demo located at (http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/edit-form-types/defaultcs.aspx)

I have been able to get the radgrid to fill with my datasource, see the edit column and popsup the edit form as I have formated it. But when I make the "Edit" and choose the "Update" nothing happens. The values seem to be getting saved, but there not going to the database. The AcceptChanges() command is where I believe it is not saving to the database.  

Below is my code behind. Any help would be appreciated. Thank you in advance.

Hi

Dear

 I have a grid with template column (item template and edit template) and i use required validation (client side) in item template because it is radtextbox, when export to excel, these fields have '*' in excel file .Why?

 <telerik:GridTemplateColumn FilterControlWidth="70%" AutoPostBackOnFilter="true" DataField="Shomaresh"
                        HeaderStyle-Width="100px" HeaderText="<%$ Resources:Resource, Shomaresh %>"
                        UniqueName="Shomaresh">
                        <ItemTemplate>
                            <telerik:RadNumericTextBox Width="100%"  runat="server" ID="rtxt_Shomaresh" Text='<%# Bind("Shomaresh") %>'>
                            </telerik:RadNumericTextBox>
                            <asp:RequiredFieldValidator ID="RFV_Shomaresh" runat="server" ErrorMessage="<%$ Resources:Resource, Shomaresh %>" Text="*" ValidationGroup="AnbarGardani" ControlToValidate="rtxt_Shomaresh" ForeColor="Red"></asp:RequiredFieldValidator>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadNumericTextBox Width="100%" runat="server" ID="rtxt_Shomaresh" Text='<%# Bind("Shomaresh") %>'>
                            </telerik:RadNumericTextBox>
                            <asp:RequiredFieldValidator ID="RFV_Shomaresh" runat="server" ErrorMessage="<%$ Resources:Resource, Shomaresh %>" Text="*" ValidationGroup="AnbarGardani" ControlToValidate="rtxt_Shomaresh" ForeColor="Red"></asp:RequiredFieldValidator>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

I think this problem comes from required validator in item template.Other template columns that are not validator ,dont have this problem.

Please help.

 Thanks.

hi 

I Have RadGrid and want Delete One Row in ItemDataBound..... 

means , when ItemDataBound appaly i want  check some Item and then delete one row .... 

 protected void gvShow_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem dataitem = (GridDataItem)e.Item;
             
             if ( check one EstateMent)
              {  

Do Some things

                }

                else
                {
                here I want Delete Current Row 
                 }

Is there a way to prevent this? It makes life difficult when you can't use the design view. (see attached)

Note, this happens everywhere in the project.

Hi,

I have a requirement to be able to navigate our website using only the keyboard (we support blind people who do not use a mouse).

We find that once a RadGrid FilterMenu has popped up after clicking the Filter button, it is not possible to close it without selecting a menu item or clicking elsewhere with the mouse. I need the menu to close when the user presses "Escape".

I cannot seem to find a way to intercept keystrokes with the FilterMenu - There doesn't seem to be an OnKeyPress event?

I hope you can help,

Thanks.
