[Solved] Dislay child nodes as new OrgChart.

Hi

There is an Orgchart in my product page which contain a main tree like structure with few nodes. If I click on one of the nodes, it must display a new OrgChart that contains all the child nodes corresponding to the one I clicked and it should be able to go back to the main node as well. How to achieve this? Is it possible with RadOrgChart?

Thanks,
Lovella.

Bind DataTable to a RadRotator

I added a telerik:RadTabStrip with multipageview option. Then under a pageview I added a Telerik Rotator control.
If I set static value it works fine, but, if I create a datatable in server side and try to bind it to datasource of the rotator control it does not display any data. The code I used -

ASPX Code:
<telerik:RadRotator ID="RadRotator1" runat="server" Width="900px" Skin="Black" EnableEmbeddedSkins="false"
                   CssClass="rotatorStyle" RotatorType="Buttons" ScrollDuration="500" >
                   <Items>
                       <telerik:RadRotatorItem>
                           <ItemTemplate>
                               <div class="RotatorItem">
                                    <h2><asp:Label ID="lblTitle" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "title") %>'></asp:Label></h2>
                                    <div class="txt_placeholder">
                                        <asp:Label ID="lblShortDesc" Text='<%# DataBinder.Eval(Container.DataItem, "desc")%>' runat="server"></asp:Label>
                                    </div>
                                    <div class="clear"></div>
                               </div>
                           </ItemTemplate>
                       </telerik:RadRotatorItem>

                   </Items>
               </telerik:RadRotator>

Server Code:

DataTable dt = new DataTable();
                    dt.Columns.Add("title", typeof(string));
                    dt.Columns.Add("desc", typeof(string));

                    dt.Rows.Add("T1", "AAA");
                    dt.Rows.Add("T2", "BBB");
                    dt.Rows.Add("T3", "CCC");

                    RadRotator1.DataSource = dt.DefaultView;

                    RadRotator1.DataBind();

Can someone please help me with this?

Thanks in advance.

ExportTo(Excel|PDF|*) & RadAjaxManager

Hi,

What I'm trying to achieve sound pretty simple considering the features offered by ASP.NET AJAX.
I have an aspx page with a RadAjaxManager. This manager "ajaxifies" the loading of usercontrols within that page.
I'm loading a usercontrol embedding a RadGrid and everything works like a charm (as expected). Then I'm trying to export the grid to an Excel spreadsheet and nothing happens.
I tried many different options as described on this page but it still doesn't work.

Here's a sample of my Default.aspx page with the RadAjaxManager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest" >

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadRibbonBarAdminTools">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PContent" LoadingPanelID="RadAjaxLoadingContextPanel">

</telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingContextPanel" runat="server">

</telerik:RadAjaxLoadingPanel>

<asp:Panel ID="PContent" runat="server">

</asp:Panel>

Here's the code behind:

protected void Page_Load(object sender, EventArgs e)

{

if (LatestLoadedControlName != null)

{

LoadUserControl(LatestLoadedControlName);

}

protected void RadRibbonBar_ButtonClick(object sender, RibbonBarButtonClickEventArgs e)

{

switch (e.Button.Text)

{

case "Summarized":

LoadUserControl("usercontrols/data-Summaries.ascx");

break;

default:

if (LatestLoadedControlName != null)

{

Control previousControl = PContent.FindControl(LatestLoadedControlName.Replace("usercontrols/", "").Split('.')[0]);

if (!Object.Equals(previousControl, null))

{

this.PContent.Controls.Remove(previousControl);

}

break;

}

public void LoadUserControl(string controlName)

{

if (LatestLoadedControlName != null)

{

Control previousControl = PContent.FindControl(LatestLoadedControlName.Replace("usercontrols/", "").Split('.')[0]);

if (!Object.Equals(previousControl, null))

{

this.PContent.Controls.Remove(previousControl);

previousControl.Dispose();

}

string userControlID = controlName.Replace("usercontrols/", "").Split('.')[0];

Control targetControl = PContent.FindControl(userControlID);

if (Object.Equals(targetControl, null))

{

UserControl userControl = (UserControl)this.LoadControl(controlName);

userControl.ID = userControlID.Replace("/", "").Replace("~", "");

this.PContent.Controls.Add(userControl);

LatestLoadedControlName = controlName;

}

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

}

I have a ribbon bar on top of my page to load the different usercontrols.

Here is my data-summaries.ascx:

<telerik:RadGrid ID="rgIGTSummaryGrid" runat="server" DataSourceID="dsIGTDataSummary"

SelectCommand="P_GetIGT_SummaryData" SelectCommandType="StoredProcedure">

<SelectParameters>

<asp:Parameter Name="sid" DefaultValue="1" />

</SelectParameters>

</asp:SqlDataSource>

and there is nothing in the code behind as I don't need anything that is described in this WORKING example.

Don't know what to do now :(

IE 10 issue for scrollbar for ASP.net RAD controls

Hi,

We have major problem with RAD controls in ASP.net with IE 10 compatibility mode ON. Please find attached Images with screenshots to explain the problem with scrollbars.

Please see below image where we can see scrollbar in IE 10. We try to scroll page right by taking our mouse to scrollbar but then
scrollbar disappears and will not allow us to scroll right.

<Page1.jpg>

Please see below screen with disappeared scrollbars.
<Page2.jpg>

If scrollbar appearing and if we use arrow key from keyword to scroll left or right then it works but through mouse cursor, we are unable to scroll.

Another related issue for IE 10 Compatibility mode ON. Please see below screen, we have grid with cut view having few columns are not visible and also header image which is not stretching to the full end when we Don’t have mouse over Grid 2.

<Page3.jpg>

If we take mouse over Grid 2, it expands grid and image to full width as displayed below and it shrink back to previous cut view if we take mouse out of Grid 2.

<Page4.jpg>

Regards,
Sunil

The problem is that when "DataBind" method is executed in "BindGrid" (called by Page_Load) also the PageSizeChanged event is raised, which, in turn causes the "BindGrid" method to be recalled, which again, raises the PageSizeChanged event and so on... until the StackOverflowException is raised... Can I know why "PageSizeChanged" is raised when I call "DataBind"?

* UPDATE *
I want to add that the PageSizeChanged event is raised not one time, but five: equal to the number of rows in the MasterTableView.

Thank you!

problems with preview mode and anchor tags

We've run into a couple problems with Preview mode of the editor. The editor version is 2012.2.724.40.

First problem:

Switching the editor to Preview mode, then back to design/html mode, onclick of an anchor tag has been removed. Example:

<a href="http://www.google.com" onclick="alert('clicked');">link</a>

changed to:

<a href="http://www.google.com">link</a>

Second problem:

Switching the editor to Preview mode and submitting the page, target="blank" has been added to the anchor tag. Example:

<a href="http://www.google.com">link</a>

changed to:

<a target="blank" href="http://www.google.com">link</a>

Are these known issues in version 2012.2.724.40 of the editor?
