Hello,telerik.

I designed one web page which has 4 rad listview that displays data loading from db.
but when I visit this page in debugging time,it is very slow.

So can I load the listview one by one ?or other way to improve the speed of loading the page?

Viewstate error on radgrid when label is added dynamically to display status message

Hello,

I have radgrid with

OnDeleteCommand

="Grid_DeleteCommand"

protected

void Grid_DeleteCommand(object source, GridCommandEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.Item;

string name= dataItem["Name"].Text;

try

{

var Id= (int)e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Id"];

DeleteItem(Id);

InsertGridMessage("Name: " + name+ " is deleted!", false);

}

catch (Exception ex)

{

InsertGridMessage(

"Name: " + name+ " cannot be deleted. Reason: " + ex.Message, true);

e.Canceled =

true;

}

private

void InsertGridMessage(string message, bool isFailure)

{

var lblMessage = new Label

{

ID =

"LblGridMessage",

Text = message,

ForeColor = isFailure?

Color.Red:Color.Green

};

Grid.Controls.AddAt(0, lblMessage);

}

When i delete the item for first time it all works fine. But any action on radgrid will throw following exception. The reason is because the viewstate is not updated. Any ideas?

I get following error

Webpage error details

Message: Sys.WebForms.PageRequestManagerServerErrorException: 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.

[Solved] Searching a RadPane with ContentURL set

Not sure how to go about this so I'm looking for any tips or ideas. Thanks

Basically I have a RadPane and I set the contentURL property to a text file on a fileshare. That is all currently working just fine. The contents of the text file show up in the RadPane.

What i have is a search variable passed into the page from a previous page and I want to search the contents of the RadPane for the search term and highlight the search term in the text document in yellow.

In addition I would really like to have a couple buttons on top (back, and next) that when clicked would automatically scroll the user to the next or previous instance of the search term within the RadPane.

Any examples or pointers would be great. I'm not even sure where to start with this.

thanks

Dynamic Modal Window Titles

I'm currently trying to set a modal window title dynamically from my stored procedure search and it works fine when I add it to the <UpdateControls><telerik:AjaxUpdatedControl> but even though it displays as it should, the window refuses to close now. I tried setting an individual UpdateControl just for the modal window but that did not work as well. A friend of mine suggested somehow using JavaScript to $find("modalComment.ClientID"); but I've never coded in javascript so this poses a bit of an issue to me. Has anyone else tried to set a dyanamic modal window titles from the backend code were able to close the window successfully?
What I currently have is:

    
                        <telerik:AjaxSetting AjaxControlID="gvSearchResults">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="gvSearchResults" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="modalComment" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="rptComments" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="modalStatus" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="rptStatus" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting>

This displays my title and dynamic content just as is should.

In my actual column that I want to call the window from an image button:

    
            <telerik:GridTemplateColumn UniqueName="Title" HeaderText="Title" InitializeTemplatesFirst="false" SortExpression="Title">  
        
                                    <ItemTemplate> 
        
                                        <table cellspacing="0" width="100%">  
        
                                            <tr> 
        
                                                <%#Eval("Title") %> <asp:ImageButton ID="imgButton" runat="server" ImageUrl="~/images/icons/16/message_add.png" OnClick="fillModalComment" /> 
        
                                            </tr> 
        
                                        </table> 
        
                                    </ItemTemplate> 
        
                                    <ItemStyle HorizontalAlign="Left" /> 
        
                                </telerik:GridTemplateColumn>

and the working title code on the backend is:

    
                    public void fillModalComment(object sender, EventArgs e)  
        
                    {  
        
                        int reqID = 0;  
        
                        reqID = int.Parse(((ImageButton)sender).CommandArgument);  
        
                        rptComments.DataSource = Comments.GetComments(reqID);  
        
                        rptComments.DataBind();  
        
                        MainSearch ms = new MainSearch(reqID);  
        
                        string title = "Comments on " + ms.Title;  
        
                        int len = ms.Title.Length;  
        
                        if (title.Length < 40)  
        
                            modalComment.Title = title;  
        
                        else  
        
                            modalComment.Title = title.Substring(0, 40) + "...";  
        
                        modalComment.Show();  
        
                    }

Any ideas that may avoid the javascript? Or is javascript a necessity in this case?

Thanks in advance.

Tooltip and an area tag

I have the following map tag on my page

<map name="mapWeeklyDeal">
<area shape="RECT" coords="773,55,902,84" href="" title="WHATS THE DEAL?" id="amWhatTheDeal">
<area shape="RECT" coords="660,52,764,87" href="SOMELINK"
target="_blank" title="Become a Fan of Baudville!">
<area shape="RECT" coords="549,54,645,88" href="SOMELINK" target="_blank"
title="Join Us on Twitter!">
</map>

What I would like to do is attach the tooltip to WHATS THE DEAL area tag and not exactly sure how to make this work, I have tried setting my tag like so

<rad:RadToolTip ID="radCustomInfoTT" runat="server" TargetControlID="amWhatTheDeal"
IsClientID="true" Sticky="true" Visible="false" AutoCloseDelay="1000" Animation="none"
Position="TopLeft" RelativeTo="Element" OffsetY="2" Height="240px" Width="400px"
Skin="Default" HideDelay="100" Title="Add Your Logo - Custom Information">
<asp:Literal ID="ltrWhatsTheDeal" runat="server"></asp:Literal>

</rad:RadToolTip>

I even tried to add the onmouseover event to the area tag in question, but then I couldn't find any code that will allow me to bring up the tooltip. So any help on this would be appreciated.

[Solved] Can I alter the Scheduler Date Header Format / css

Hello,
I am having a bit of an issue with the rendering of my scheduler. the area I am rendering it in is causing the header date(s) to be cut off.
Is there a way I can alter the format or css to compensate for the lack of space? I see that there is a lot of space left of the date. If I could even just move the date left a bit that would probably be enough. I have attached an image to illustrate:

First entered character ignored with ShowDropDownOnTextboxClick

I have ShowDropDownOnTextboxClick set to False, and as expected when the user sets focus to the text box nothing happens.

When the user types into the text box the first character typed correctly opens up the dropdown showing matching items, but the character does not appear in the text box. Subsequent characters do appear. Is this expected behaviour?

Rad Upload error

We had to move a website to a new server. We went from win2k iis 6 to win2k8 iis 7. Now, whenever I use the rad uploader I get a popup with this error.

Rad Upload Ajax callback error. Source url was not found:

Telerik.radUploadProgressHandler.ashx?RadUrid=004b9887-1c02...

Did you register the RadUploadProgressHandler in the web.config?

Please, see the help for more details: RadUpload for ASP.NET Ajax -
Configuration - RadUploadProgressHandler

I saw this post http://www.telerik.com/community/forums/aspnet-ajax/upload/radupload-ajax-callback-error-source-url-returned-error-500.aspx and did what it had said but it didn't fix my problem. I have attached my web.config
