[Solved] How to make a tree view like frameset click?

Dear all,
I have just bough the whole package of telerik and I think they should be good to go in my project :)

My question is, in asp.net treeview control, there is a property call "NavigateUrl" and if u click on it, it will redirect to another page with whole page refresh, and then the state of treeview is clean.I know the answer is the new page is a link, so it would be considered as a new page. How does this radcontrol to handle this saturation? Such as saving the treeview state, and click on the node with no refreshing...I know there is multipage of radcontrol, but I think that will be preloaded all of my pages in multopage, so it will slow down the process...

Please advice, thx.

Best regards,
Stephen

At run time, I have to wait for a long time to load the drop down after clicking the arrow.
Is there any other methods to make it fast.
Please help.

radUpload loadedcontrol in ajax multipage

Hi,

I have many problems to fix this scenario. I need to use one radUploader usercontrol loaded in one ajax multipanel but i can't loaded my files. I have used the conditionalPostback registred from loaded usercontrols to stop ajax refreshing or created a realPostBack in page and registred in page-Load of Loaded usercontrol but still not working.

Use the wizard sample of demo of RadTabs and loading one RadUploader control

    
            <telerik:RadAjaxLoadingPanel  runat="server" ID="LoadingPanel1" IsSticky="true"> 
        
                </telerik:RadAjaxLoadingPanel>         
        
                <telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="LoadingPanel1" > 
        
                        <telerik:RadComboBox  runat="server" ID="RadComboTipo" Skin="Vista"  AutoPostBack="true" Width="200px" 
        
                         OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"  > 
        
                                        <Items> 
        
                                            <telerik:RadComboBoxItem Text="Select" Value="-1" Selected="true"></telerik:RadComboBoxItem> 
        
                                            <telerik:RadComboBoxItem Text="Case1" Value="1" ></telerik:RadComboBoxItem> 
        
                                        </Items> 
        
                        </telerik:RadComboBox> 
        
                        <div style="height:33px;"></div> 
        
                        <telerik:RadTabStrip ID="RadTabStrip1" SelectedIndex="0" runat="server" MultiPageID="RadMultiPage1" 
        
                            Skin="Default" CssClass="tabStrip"> 
        
                        </telerik:RadTabStrip> 
        
                        <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated" CssClass="multiPage"> 
        
                        </telerik:RadMultiPage> 
        
                </telerik:RadAjaxPanel>

The LoadedControl in pageView use RadUploader and page load to register realPostBack and stop the ajax event.

    
            bool isOnClickAttached = false; 
        
                    IEnumerator keys = this.buttonSubmit.Attributes.Keys.GetEnumerator(); 
        
                    while (keys.MoveNext()) 
        
                    { 
        
                        if (keys.Current.Equals("onClick")) 
        
                        { 
        
                            isOnClickAttached = true; 
        
                            break; 
        
                        } 
        
                    } 
        
                    if (!isOnClickAttached) 
        
                        this.buttonSubmit.Attributes.Add("onClick", string.Format("realPostBack('{0}', ''); return false;", this.buttonSubmit.UniqueID));

This realpostback is firing but no upload is performed.

Use one ClientEvents-OnRequestStart="conditionalPostback" in RadAjaxPanel1 is not possible in this scenario where controls are loaded in the panel.

The object is one Ajax RadTab and one RadUpload control loaded inside and fonctional. Some suggestions. Thanks.

[Solved] HeaderStyle doesn't set column width properly with IE 7.

When I set the column width with HeaderStyle property with the below statement, the columns are rendered 200 pixels with IE8, Firefox, Opera and Safari but 216 pixels with IE7. I am using 2009 Q2 SP2 and I am using WebBlue skin.

<HeaderStyle Width="200px" />

If you check column width of the below radgrid example first with IE8 and than with IE7 compatibility view you'll see what I mean.

Horrible HTML

How do you answer the question - why does controls like an Text box generate (such horrible html) of tables instead of a <input text box.
Its no good saying cos it can connect to a WCF source or do google style predictive searches.
What we have done is to have a designer is to look at the rendered HTML+css and then alter the .ri classes.
I know I could use the form decorator for some but there seems to be a lack of understanding of the benefit of using say the RadInput controls.
The most irritating is to create a search text box with a seprate button, or a input box with error icons next to it or a checkbox with label centered and error icon (eg you must tick the T&Cs) all in a line, eg text-align.
The bit about internationalization or accessiblity its stony ground.

What can you suggest?

[Solved] How to get DIV properties inside EditPopup

Hi,
I am using NestedGrid, i have parent grid and it has the nested grid that is child grid. Both grid has the functionality of editing with EditPopup window. I used the "PopUpShowing" event commonly for both grid in order to place the Popup in center. I used the DIV elements to place and bind the controls inside the EditFormTemplate section

My question is when the PopUp is showing once edit button is clicked I just want to get the DIV prperties of EditFormTemplate section of the corresponding PopUp window regardless parent or nested grid.

My purpose is the setting the PopUp height and width dynamically based on the container or DIV height and width. Because I already told the DIV used the place the controls, the DIV has its width and height property.So i just want to take this width and height values for dynamic operation

So is there any possible ways please let me know.

-Thanks in Advance
