Save an record in ToolTip and Comunicate about it the mainpage

I need to save one new record in tooltip and to comunicate about it the page. How could I do it?

With this code I load control in the tooltip.

protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)

{

this.UpdateToolTip(args.Value, args.UpdatePanel);

}

private void UpdateToolTip(string elementID, UpdatePanel panel)

{

var idanagraficatipo = -1;

int.TryParse(ddlCentroRichiedente.SelectedValue, out idanagraficatipo);

Control ctrl = Page.LoadControl("~/controls/preaccettazione/Anagrafica.ascx");

panel.ContentTemplateContainer.Controls.Add(ctrl);

controls_preaccettazione_Anagrafica details = (controls_preaccettazione_Anagrafica)ctrl;

details.IdAnagraficaTipo = idanagraficatipo;

}

I try to save record in the control but the problem that after postback I find textboxs empty.

Thank you,

Ines

[Solved] Duplicate pie slice colors?

I have several pie charts developed within the Telerik Reporting component. These pie charts are using the default slice colors. The problem is that the chart is generating two adjacent slices with the same color. This seems to be happening when there are 7 slices, and two of the slices next to each other are both blue.

Is this unusual? Is there a solution other than setting my own colors in the code-behind?

Thanks.

UseStaticHeaders issue

I have a RadGrid and something strange seems to be happening with my Javascript when I have UseStaticHeaders set to TRUE.

I have the following line of Javascript:

var

orgIdCell = rgUsers.MasterTableView.get_dataItems()[i].get_cell("OrgIDColumn");

If UseStaticHeaders = FALSE, orgIdCell is populate and there are no problems.

If UseStaticHeaders = TRUE, orgIdCell comes back as NULL.

Why?

is there a workaround?

I need to use orgIdCell to access the innerText propery of a cell in the grid.

I am setting UseStaticHeaders and AllowScrolling to True/False in c# based on some conditions and other button clicks.

It seems that if both UseStaticHeaders and AllowScrolling are set to True, this issue occurs. If only one or the other are set to TRUE, this issue does not happen.

Thanks,
Dave

                    e.UpdatePanel.ContentTemplateContainer.Controls.Add(toolTipPanel)  
        
                End Sub

All works fine untill I select a diary entry after this the tool tip still works but as the mouse moves over the other cells the background colour is reset.. Is there anyway I can use JS to keep the colour using a custom client side events.... or am i missing somthing else

HTML encoding for RadTreeNode.Text fails

Hello

I use RadTreeView with load-on-demand feature (ServerSideCallback). When a node is expanded I create child nodes and do HtmlEncode for its' texts. I see "<input>" text as "<input>" and that's OK. But when I click any child node (I have server-side Click handler that actually do not change any nodes) all "<input>" nodes become text boxes!

I guess it's a bug. Could you give me some workaround?
Thanks.

Grid Paging doesn't work

I am currently running into a major issue where when using the paging navigation and I try to move to the next page nothing happens. I get a brief flash where the grid header row's columns adjust and then settle back to their original widths.

I might assume it's something with a Script or RadManager maybe?
Anyone have any suggestions?

"Cannot Write To Target Folder" Error

I have a File Explorer:

    
            <telerik:RadFileExplorer   
        
            ID="EquipmentFileExplorer"

            InitialPath="~/AppData/Uploads/" 
        
            VisibleControls="TreeView, Grid, Toolbar, ContextMenus">  
        
            <Configuration   
        
            MaxUploadFileSize="2004800"   
        
            SearchPatterns="*.doc,*.pdf,*.gif,*.jpg,*.jpeg,*.tif,*.tiff"   
        
            DeletePaths="~/App_Data/Uploads/" 
        
            UploadPaths="~/App_Data/Uploads/" 
        
            ViewPaths="~/App_Data/Uploads/">  
        
            </Configuration> 
        
            </telerik:RadFileExplorer>

When I run the project, either locally or on a dev server, I receive an alert saying "Cannot Write To Target Folder". NETWORK SERVICE has modify set on the folder, so it should be ok?

I am using the latest ASP.NET release. Puzzled.

Columns don't have unique values error

Please ignore this post, I found an error in the SQL Statement

I attempting to populate a tree view via databinding and keep getting the error columns don't have unique values. The dataset results I'm binidng to is repeated below. The parent ID column has dupes because many of the parents have multiple children which I assume is fine, but the ID field is unique for all of the records. Obviously I'm missing something but I don't get it, any guidance is appreciated.

Also, here is my binding code:

Me

.RadTreeView1.DataSource = oDS.Tables(0)

Me.RadTreeView1.DataFieldID = "ID"

Me.RadTreeView1.DataFieldParentID = "ParentID"

Me.RadTreeView1.DataTextField = "Name"

Me.RadTreeView1.DataValueField = "ID"

Me.RadTreeView1.DataBind()

SortedBackColor & Header

Hi
I have a problem with the SortedBackColor of the column, it goes to cover the middle line of the head and the text is hidden.
Is normal and I have to change the text color of the head ? or it is a problem of the command ?
