Hi,

I have attached RAD confirmation dialog box with my ASP.net button OnClientClick. It woks fine but it doesn't fire server side click event of button whether I select Ok or Cancel.

I am using following code

<

asp:Button ID="btnDelete" runat ="server" Text ="Delete" cssclass="RadUploadSubmit" OnClientClick="return OpenConfirm();"

Visible="False" />

function OpenConfirm() {

radconfirm(

'<h3 style=\'color: #333399;\'>Are you sure?</h3>', confirmCallBackFn, 330, 100, null, 'RadConfirm custom title');

return false;

function confirmCallBackFn(arg) {

radalert(

"<strnog>radconfirm</strong> returned the following result: <h3 style='color: #ff0000;'>" + arg + "</h3>", null, null, "Result");

}

Please tell me where do I modify javascript so it fires server side click after User selects Ok on confirmation dialog.

Thank you.

Changing datasource combo in Radgrid Form template?

Hi, I'm using Form Template in my radgrid. I have several combobox that when I change, I wanted to change other combobox datasource. For instance 1st combo is course, 2nd is Level and 3rd is teacher. If i'm going to change my course combo it will change data for my level and teacher combo.

Any inputs would be a great help.. Thanks in advance..

Heres some sample code:

    
            <EditFormSettings EditFormType="Template">  
        
                                <FormTemplate>

Dynamic Radtreeview - Maintain state

Hi,

I am creating RadTreeView in NewItemTemplate class of RadPanel. I have this code in an usercontrol.

I am using Radwindow to create new nodes for the Tree ( I am calling radwindow using a button inside usercontrol). On Closing for RadWindow I want to highlight/select the node which is recently added to the tree.

How do I achieve this?

                    For example,         
                     
            public void InstantiateIn(System.Web.UI.Control container)         
            {         
              RadTreeView RadTreeView1 = new RadTreeView();         
              RadTreeView1.ID = "myTree" & myNumber         
              RadTreeView1.DataTextField = "Text";         
              RadTreeView1.DataNavigateUrlField = "Url";         
              RadTreeView1.DataFieldID = "ID";         
              RadTreeView1.DataFieldParentID = "ParentID";         
              RadTreeView1.DataSource = siteData;         
              RadTreeView1.DataBind();         
            }         

Thanks

Convert string to int

I am having an issue with a conversion. I have a Telerik RadMenu loading via a Linq to Sql class. I am then trying to invoke a onclick event on a menu item. I am trying to pass the menu item field id as a parameter. See code below.

The problem is, the idProjects is an int and @linkId is a string. I get an error that says @linkId cannot be implicitly converted from a string to an int. How can i make this work?

            string linkId = RadMenu1.DataFieldID.ToString();

            SundownDataContext dc = new SundownDataContext();
            var q = (from projects in dc.GetTable<ProjectImage>()
                     where projects.idProjects = @linkId
                     select new
                     {

                         Title = projects.projTitle,
                         ImageURL = projects.projImage
                     }).FirstOrDefault();
            Label1.Text = (q != null) ? q.Title : "Not Found";
            Image1.ImageUrl = q.ImageURL;

msi installs OK in Vista, but not in Win2k3R2SP2

After successfully installing RadControls_for_ASP.NET_AJAX_2009_2_826_trial.msi in Windows Vista Ultimate SP2 I took the exact same msi and tried to install it on Windows Server 2003 R2 SP2, but this time, after seeming to start fine, it puts up the following error pop-up:

The cabinet file 'media1.cab' required for this
installation is corrupt and cannot be used. This
could indicate a network error, an error reading
from the CD-ROM, or a problem with this
package.

Retry Cancel

No amount of Retry attempts helps.

Please don't tell me to download a fresh copy. This is the exact same MSI file that had zero problems installing on Vista SP2, so I am 100% confident that the msi is not corrupt.

[Solved] 100% Height

I've tried a number of examples here from the forum to try and solve my problem of having the rad splitter sit at 100%, but with no luck.

I have a relatively simple web page with a header, content area (where the splitter sits), and a footer. For some reason, the splitter won't go past about 50% of the screen height. I've made sure that the elements outside of the splitter are sized to 100%. In fact, I've added a quick border statement to them to make sure that everything extends to the bottom of the page, and it does (all except the splitter).

I'm attached a screenshot to this thread, and a sample project built with Q2 2009 can be downloaded here. I've removed the telerik.web.dll references from the bin folder to make the zip file smaller.

Any help is greatly appreciated!

Thank you,

Alex

Problems adding a RadToolBar to a custom WebControl

I've implemented a client facing web-portal which uses several data-bound composite WebControls from a library and allows our clients to view their data from within our databases. My problem is with the WebControl that creates and adds a RadToolBar to it's Controls collection during the CreateChildControl override. Seems the only way it will work is if I set the RadToolBar.EnableViewState property to false...otherwise I get the following error at each postback,

        Failed to load viewstate. The control tree into which viewstate is being loaded must match the
        control tree that was used to save viewstate during the previous request. For example, when
        adding controls dynamically, the controls added during a post-back must match the type and
        position of the controls added during the initial request.

I have another WebControl in the same library that adds a RadMenuBar the same way and it works fine...example, this fails at postback unless I uncomment the bolded statement,

    public class MyWebControl : WebControl, INamingContainer
    {
        protected override void CreateChildControls()
        {
            this.Controls.Clear();

            RadToolBar toolBar = new RadToolBar();
            toolBar.ID = "MyToolBar";
            //toolBar.EnableViewState = false;

            this.Controls.Add( toolBar );

            base.CreateChildControls();
        }
}

...yet this works fine
    public class MyWebControl : WebControl, INamingContainer
    {
        protected override void CreateChildControls()
        {
            this.Controls.Clear();

            RadMenu menu = new RadMenu();
            menu .ID = "MyMenu";

            this.Controls.Add( menu );

            base.CreateChildControls();
        }
}

Anyone know what the problem is??

[Solved] Ajaxing UserControls/ASP:Repeater

I am prototyping a data driven data entry form. I have a UserControl that will vary appearance and validation based on data values provided through an asp:repeater control.. My problem is that the first time a value is entered and the AutoPostBack is triggered, a regular postback occurs not an Ajax callback. It doesn't matter which Field is entered first and any subsequent AutoPostBacks on the first field or any other of the repeater fields appear to do Ajax call backs properly. Any help appreciated.
