Dynamically created combo box losing value after multiple postbacks

I've run into a problem using the asp.net ajax RadComboBox that is dynamically added to the page, which is caused by it losing its value if more than one postback occurs.

I select an item in the combobox and then trigger a postback. After the first postback the initially selected value is still selected, but after a second postback it is not. The old style RadComboBox and the built in DropDownList both retain their selected value.

Here's a simple test example that shows the problem. The aspx simply contains a repeater with a placeholder inside it.

    
                    <asp:ScriptManager ID="scriptManager" runat="server"></asp:ScriptManager> 
        
                    <asp:Repeater ID="repTest" runat="server"> 
        
                        <ItemTemplate> 
        
                            <div> 
        
                                <asp:PlaceHolder ID="plcTest" runat="server"></asp:PlaceHolder> 
        
                            </div> 
        
                        </ItemTemplate> 
        
                    </asp:Repeater> 
        
                    <asp:Button ID="btnTest" runat="server" Text="PostBack" />

In the ItemDataBound event handler the combo boxes are created and added to the placeholder. If I select Item 2 in each combo box and then click the button twice then at the end the first two combo boxes still have Item 2 selected but the asp.net ajax RadComboBox has reverted to Item 1.

    
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                        repTest.DataSource = new int[] { 1, 2, 3 }; 
        
                        repTest.DataBind();

                        base.OnInit(e); 
        
                        repTest.ItemDataBound += new RepeaterItemEventHandler(repTest_ItemDataBound);

RadGrid: Drag and Drop doesn't work when we have a vertical scroll bar.

Hi,

I have a RadGrid with Items Drag-and-drop functionality. It works great unless I have more than 6 rows which allows a vertical scroll bar in the grid. When I have a vertical scroll bar and try to drag the last item/row to the first or second row, it doesn't work. I have attached snap shots and code.

Looks like the issue is with IE8 Browser.

Please help.

Thanks

[Solved] Get page title from page in RadPane

I've got a site using RadSplitter with two RadPanes. One is navigation the other content. I want the browser tab title to reflect the title of the web page showing in the content pane.

I've tried something like this from a interval timer. But iframe.document.title is not the title of the web page. Any ideas?

var iframe = $find("<%= ContentPane.ClientID %>").getExtContentElement();

document.title = iframe.document.title;

Rating Items ImageURL

All the standard ASP.net controls that have a ImageURL property accept relative urls (ex. ~/img/image.gif)

When I place a relative URL into a Rad Rating Item, it doesn't resolve the URL, it simply embeds this as a literal value to the page's CSS.

<telerik:RadRatingItem CssClass="ratingItem" Value="1" ImageUrl="~/img/ratings/rating_1_normal.png" ToolTip="Very Easy" SelectedImageUrl="~/img/ratings/rating_1_selected.png" HoveredImageUrl="~/img/ratings/rating_1_hover.png" />

I can adjust the URL's accordingly by removing the ~/ and change it to an absolute path, however when published to a server sometimes the path is a little different. This results in the images not displaying because the CSS is pointing to the wrong place. Is this by design?

I used this code to resolve the URLs so that I could use relative paths in the image URL properties:

If String.IsNullOrEmpty(item.ImageUrl) = False Then

If item.ImageUrl.StartsWith("~/") Then

item.ImageUrl = ResolveUrl(item.ImageUrl)

End If

If String.IsNullOrEmpty(item.SelectedImageUrl) = False Then

If item.SelectedImageUrl.StartsWith("~/") Then

item.SelectedImageUrl = ResolveUrl(item.SelectedImageUrl)

End If

If String.IsNullOrEmpty(item.HoveredImageUrl) = False Then

If item.HoveredImageUrl.StartsWith("~/") Then

item.HoveredImageUrl = ResolveUrl(item.HoveredImageUrl)

End If

If String.IsNullOrEmpty(item.HoveredSelectedImageUrl) = False Then

If item.HoveredSelectedImageUrl.StartsWith("~/") Then

item.HoveredSelectedImageUrl = ResolveUrl(item.HoveredSelectedImageUrl)

End If

Is there ever going to be an implementation of allowing relative paths in the image URL fields?

RadEditor is activating in IE, I do not want it to!

Hi,

We have RadEditor 5.8.12.0 and MOSS 2007.

RadEditor works fine in non-IE browsers, but it also is activated in IE. I have not specifically activated it, just deployed it in Solution Management after un-deploying the Lite 4.5 version.

I would like RadEditor to NOT activate in IE, instead using the MOSS built-in rich text editor.

How do I achieve this?

Many thanks

Mark

UNABLE TO SEE PROGRESS BAR WHEN CALLED ASYNCHRONOUSLY

Hi,

I have created a custom progress bar usercontrol using RadProgressArea. I have placed this control in one of my web page. On a button click event a usercontrol method will be triggered. This method in turn will trigger the UpdateProgressContext method for setting the Radprogresscontext. The progress percentage will be retrieved using progressMethod. The RadProgressBar is getting displayed.
But if I try to call the UpdateProgressContext method asynchronously using delegate, my progressbar itself is not displayed. This is my code.

private delegate void BeginProgress(Progress prog); 



public Update(Progress progressMethod)

{

BeginProgress beginUpdate = new BeginProgress(UpdateProgressContext);

    beginUpdate.BeginInvoke(progressMethod, new AsyncCallback(ProgressCallbackMethod), new object()); 

}

private void UpdateProgressContext(Progress progressMethod)

{

int currentPercentage = 0;

const int total = 100;

while (currentPercentage <= 100)

{

currentPercentage = progressMethod();

radProgress.Speed = "N/A";

radProgress.PrimaryTotal = 1;

radProgress.PrimaryValue = 1;

radProgress.PrimaryPercent = 100;

radProgress.SecondaryTotal = total;

radProgress.SecondaryValue = currentPercentage;

radProgress.SecondaryPercent = currentPercentage;

radProgress.CurrentOperationText = "Step " + currentPercentage.ToString();

radProgress.TimeEstimated = (total - currentPercentage) * 100;

}

Any help will be appreciated. Thanks in advance.

Regards,
Subbu
