Hi,

I need to make this control to be accessibility compliant. I have already patched it for aria-markup, but when I turn on high contrast mode, the images for collapsing/expanding the control and the nodes, just disappear.

I have placed a span with "+" and "-" symbols just before the "rtSp" span. But now the problem is that I need to keep them synchronized with the status of the node (expanded or collapsed).

I am trying to avoid to manually place events in all of the objects that can originate an expand/collapse operation.

Do you have a client event for expand or collapse that I can use to update the status of the node?

Thanks

Hi,
I have a TreeList control, with an insert template as below:

            <EditFormSettings EditFormType="Template">
                <FormTemplate>
                    <table>
                        <tr>
                            <td>Is this a header:
                            </td>
                            <td>
                                <asp:checkbox ID="cbIsHeader" runat="server" />
                            </td>
                        </tr>                       
                        <tr>
                            <td>Header Text:
                            </td>
                            <td>
                                <asp:TextBox ID="txtNewHeader" Text='<%# Bind("DepartmentList_Header")%>' runat="server">
                                </asp:TextBox>
                            </td>
                        </tr>
                        <tr>
                            <td>Department</td>
                            <td><asp:DropDownList runat="server" ID="ddlDepartments"/></td>
                        </tr>
                    </table>
                    <asp:Button ID="btnUpdate" Text="Insert"
                        runat="server" CommandName="PerformInsert"></asp:Button>
                    <asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False"
                        CommandName="Cancel"></asp:Button>
                    <asp:HiddenField ID="hfParent" runat="server" Value='<%# Bind("DepartmentList_Parent")%>' />
                </FormTemplate>
            </EditFormSettings>

I am trying to pre-populate the drop down menu from a stored procedure, but not certain how this could be accomplished. Can anyone help?

In my application, I save the user preferences/settings for all docking when the user closes the application.  If they accidentally click on the "X" to close a dock, when they load the application again, it does not load that dock panel.  I have to delete their preferences.xml file so that it erases all preferences.

Does anyone know how to disable the close button on a radDock or radPanel control?

Thanks!

Maybe it's impossible to do, probably is.

If I do have 300,000 rows of data,  I'm guessing grouping in 1 large grid with no paging wouldn't work so well.

I'm working on a small project for work and I'm using Telerik:RadGrid controls. I'm trying to pass a query string with the DO name in the GridHyperLinkColumn. When the page renders and I hover over the link the query string is null (ie: GMRanking.aspx?DO=). It seems like a binding issue but I'm at a loss. Thanks in advance for your help.

I'm populating the grid like so:

    var contestResults = ContestBiz.GetGMData();

    GMGrid.DataSource = contestResults.Select(x => x.DoName).Distinct();

    GMGrid.DataBind();

Here's what I've got in the aspx

            <Columns>               
                <telerik:GridHyperLinkColumn 
                    Text="Select"
                    HeaderStyle-Width="50px" 
                    UniqueName="Link" 
                    DataNavigateUrlFields="DO"
                    DataNavigateUrlFormatString="~/GMRanking.aspx?DO={0}">
                </telerik:GridHyperLinkColumn>

                <telerik:GridBoundColumn DataField="DO" 
                    HeaderText="DO" UniqueName="DO" >
                    <HeaderStyle HorizontalAlign="Left" Font-Bold="true" />
                    <ItemStyle HorizontalAlign="Left" />
                </telerik:GridBoundColumn>                
            </Columns>

Hello,

I have an RadComboBox with autopostback set to "true". I've also a requiredvalidator on the RadComboBox. The Combo containes a "Select" element with a value "-1". When I switch from one item to the "Select" item, the validator fires and displays but the combo still makes a postback.

Sample:


Telerik version is 2010.2.826.35

Any idea?

Best regards

I have implemented the custom upload handler and per the demo and it all works fine except, for uploading any images larger than 2 mb.

The file gets uploaded but,the images are corrupted.
Also, I tried creating a thumbprint of the file as it is being uploaded but I get and error when trying to creating and image from the stream.
throws error "invalid parameter".

I would guess there is some settings in web.config which have missed but I can't work it out.

Thanks
Karl
