Hi,

I have a radgrid in which i have paging enabled. The pager style is numeric. When i mouse over the pager links (1, 2, 3,... etc numbers) i am not seeing a title on them. Can anyone please suggest if i can enable titles on these while constructing the pager itself?

Thanks,

Swamy.

 Radgrid is not refreshing at client side but at the server side radgrid contains Newly added row ,
I added a keydown event for the textbox "txtPartDescription" 
  in the Keydownevent i handled Tab key  ,  i called Radajaxmanager_ajaxRequesr("Newrow") to insert new row into datasource and i assigned data source to radgrid . but radgrid is not refreshing at the browser it showing old data and also client event s are not working after binding .

Thanks in advance .
   Please suggest any other approach to handle this  .
  please check the below code  

        protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
        {
            if (e.Argument == "NewRow")

I am using Moss 2007 with Rad Controls.  In one of my sharepoint pages i am having a RadHtmlField control.  When i Click on the "Image manager" icon in the control a list of folders show up in a popup. 

Was trying to find out where these folders are configured, so that I can change to a different folder.  Can you please help.

Thanks,
Mike

 

Telerik,

Are there any examples/tutorials that have radtabstrip and radmultipage with radpageview load on demand contenturl?

I want to be able to load a pageview with a contenturl on demand.  Something like the following:
http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

but with contenturl instead of usercontrol.

Thanks.

I'm populating a treeview in c# asp.net and have bound data to it, all well and displays as it should. my problem now is that i'm looking to save any modifications to the checkboxes i.e if a user clicks an additional box and saves but i the checked state will stay false.

here's what i have so far which iterates through what was initially loaded and not what has been changed, I've tried many variations but haven't managed to get it working - anyone any ideas??

public void saveCheckedItems()
{

    if (treeListItems.CheckedNodes.Count > 0)
    {
        IList<RadTreeNode> allNodes = treeListItems.GetAllNodes();

        for (int i = 0; i < allNodes.Count; i++)
        {
            RadTreeNode node = (RadTreeNode)allNodes[i];
            string fileid = node.Value.ToString();
            if (node.Checked == true)
            {
                if (fileid.Length == 12)
                {
                    saveTreeChanges(Page.Request.QueryString["ID"], fileid,connectionStr);
                }
            }
        }
    }
}

edit -

creating treeview as follows

<telerik:RadTreeView ID="treeListItems" runat="server" CheckBoxes="True" Height="320px"
                            TriStateCheckBoxes="true" CheckChildNodes="true" Skin="WebBlue" CssClass="table table-bordered" OnNodeDataBound="RadTreeView1_NodeDataBound" >
                        </telerik:RadTreeView>

binding data like this

public void loadTreeList()
        {
            DataTable dt = treeMan.getTreeList(connectionStr);
            treeListItems.DataTextField = "Description";
            treeListItems.DataValueField = "FieldID";
            treeListItems.DataFieldID = "FieldID";
            treeListItems.DataFieldParentID = "ParentID";
            treeListItems.DataSource = dt;
            treeListItems.DataBind();
            treeListItems.ExpandAllNodes();
        }

in the example im testing its a 3 tier tree and one element is checked on third tier. When i click more items only this already checked item is visible in the list

I am getting the Invalid length issue frequently in my application. Using of SessionPageStatePersister from earlier implementation  hiddenfieldpagestatepersister did not resolve the issue.

I am looking for a client or codebehind method to change the size of the Template Manager's iframe to match the sizing from User's template html.  A User will uploads various sized html templates and we want to adjust the size of the preview in iframe accordingly.

HI All

We are getting an error while trying to upload an image using RadEditor Control. We are getting a javascript error.

Message: Object doesn't support this property or method
URI: /ScriptResource.axd?d=...........................

Message: Sys.ArgumentException:  does not derive from Sys.Component.
URI: /ScriptResource.axd?d=................................................


Don't know what is happening but the same control works in a different server where  we could upload images.

But in 2 other servers we get an error as mentioned above while uploading an image.

Thanks

hi,

you can write a message as well as the image of the loading? For example loading please wait ...

Bye

Dear Telerik,

I'm using RadChart v2012.1.215.35 in an ASP.NET 3.5 application hosted on Win Server 2008 R2 / IIS 7.5 and I am getting a write permission error to the temporary images folder despite all users having full control access to the folder. The application is using the ASP.NET State Service for storing session state which was causing RadChart to throw a serialization error when using out of proc session state. Checking the forums for resolution I have changed Rad Chart to use a temporary folder for storing the chart images instead of session.


The security on the Temp folder is setup with the app pool service account, ASPNET user, NETWORK SERVICE, and Everyone with Full Control to the directory but the application is throwing the following error:

A generic error occurred in GDI+. Check the folder specified in the TempImagesFolder property of the control. Current value is "/App/Temp". The folder should exist and must have been granted write permissions for the ASPNET user. *** Source *** Telerik.Web.UI *** Target Site *** Void RenderClassic(System.Web.UI.HtmlTextWriter) *** Stack Trace *** at Telerik.Web.UI.RadChart.RenderClassic(HtmlTextWriter writer) at Telerik.Web.UI.RadChart.RenderContents(HtmlTextWriter writer) at System.Web.UI.WebControls.WebControl.Render(HtmlTextWriter writer) at Telerik.Web.UI.RadDataBoundControl.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.HtmlControls.HtmlContainerControl.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.HtmlControls.HtmlForm.RenderChildren(HtmlTextWriter writer) at System.Web.UI.HtmlControls.HtmlForm.Render(HtmlTextWriter output) at System.Web.UI.HtmlControls.HtmlForm.RenderControl(HtmlTextWriter writer) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Page.Render(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Any advice would be appreciated. 

Thanks,
Andrew.
