Hi,

How can I pass parameters to Lightbox from Radgrid Item_DataBound? I am trying to bind RadHtmlChart based on RadGrid DataKey value. Here is my code. Could you please let me know? I am not sure how to do this. I just upgraded our projects to new controls. Thanks for any help.

I am trying to paging for detail table in RadGrid. but when i click on page's it is getting back to grid bind.

My code is :-

  <telerik:RadGrid ID="rdSettings" runat="server" AllowPaging="true" width="100%" AutoGenerateColumns="false"
                        OnDetailTableDataBind="rdSettings_DetailTableDataBind" Skin="Metro" OnPageIndexChanged="rdSettings_PageIndexChanged" OnPageSizeChanged="rdSettings_PageSizeChanged" Visible="false">
                    <MasterTableView  DataKeyNames="Module">
                    <DetailTables>
                    <telerik:GridTableView Name="group" Width="100%" AutoGenerateColumns="false">
                      <Columns>
                        <telerik:GridTemplateColumn ItemStyle-Width="5%">
                           <ItemTemplate>
                                <asp:CheckBox ID="chkGroup" runat="server" AutoPostBack="true" OnCheckedChanged="chkGroup_CheckedChanged"/>
                          </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridBoundColumn DataField="groupname" UniqueName="groupname" HeaderText="Group" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center">
                            </telerik:GridBoundColumn>
                      </Columns>
                    </telerik:GridTableView>
                    </DetailTables>
                         <Columns>
                            <telerik:GridTemplateColumn HeaderText="Select">
                                <HeaderTemplate>

                                </HeaderTemplate>
                                <ItemTemplate>
                                    <asp:CheckBox ID="chkmodule" runat="server" OnCheckedChanged="chkmodule_CheckedChanged" AutoPostBack="true" />

                         </Columns>
                    </MasterTableView>
                </telerik:RadGrid>



And Detail Table code is



protected void rdSettings_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e) // Bind's the nested Grid for Page Settings
    {
        string groupname = "";
        GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
        switch (e.DetailTableView.Name)
        {
            case "group":
                {
                    groupname = dataItem.GetDataKeyValue("Module").ToString();
                    string sqlquery = "select distinct(groupname) from [dbo].[POColumns] where module= '" + groupname + "'";
                    SqlDataAdapter da = new SqlDataAdapter(sqlquery, ScrCon);
                    DataSet ds = new DataSet();
                    da.Fill(ds);
                    if (ds.Tables[0].Rows.Count > 0)
                    {
                        e.DetailTableView.DataSource = ds;
                    }
                    break;
                }
        }
    }


Please help out what else i have to do get the paging in Detail Table

I need to allow users to upload images and then do basic editing of them for crop, resize, gamma etc and being able to skew/deskew or de-trapezoid! them - is this functionality already in the RADImageEditor? If not would I be able to extend it easily to support skew or is it better to look at another SDK which has this as inherent functionality?

Thanks,
M

Hi, I am getting this error in Chrome (it's "unable to get property 'firstchild' of undefined or null reference" in IE) when trying to open a RadWindow as a result of a callback.
Subsequent calls of the same callback throw "Cannot read property 'style' of null".
In the callback there's a RadWindowManager.open(url, "popupwnd") that calls some JQuery which in turn definitely throws this error.

I tried every version from 2013.2.717 to the latest nightly build. It still works fine in version 2013.1.417, but I need to support IE11.

Any idea on how to fix or debug it?

Thanks

I have a user control which contains a RadGrid and two RadDatePickers that let you choose the date range for the grid's data source. I've set up a submit button to trigger a partial postback to update the grid with data for the selected date parameters using a RadAjaxManager.


This user control is on a SharePoint 2007 page layout & master page. When debugging, I noticed the first time btnLoadHistory is pressed, the Page_Load event was occurring twice. The first time IsPostBack was true, the second time it was false. Using Fiddler, I found that when I press the button, it does the async postback (POST to the page) as you'd expect, when it gets the response, I see the RadGrid update, and then it immediately does a GET on the same page, hence the IsPostBack == false the second time. It only happens the first time after the page initially loads. After that I can click btnLoadHistory and only the expected postback occurs. Any ideas what's going on?

i am creating tab by using tabstrip with scrolling for multitab .when multiple tab is created like for e.g consider the no. of tabs as 14. initially the scrolling appears but when i  am deleting tab from 14,13, and so on at a point like when i am at tab 8 after deleting the scrolling disappears along with the starting tabs i.e tab1,tab2,tab3. Scrolling disappearing at a point is right but the starting tabs are hidden which causes a problem.
