Execute onload javascript function of user control when control is dynamically loaded within a radajaxpanel.

I currently have a page that dynamically loads a user control when a button click is executed. The user control is placed on the page and loaded within a radajaxpanel. I need to run a javascript function at the completion of the user control being loaded that accesses controls within that user control. I have tried a few different ways to get this to happen, but I am unable to get it to work.

What does work is when I remove the radajaxpanel and then at the bottom of the ascx page I include the javascript function that I want to run followed by window.onload = functionToRun, but then I get the page reload etc.

I have tried to register the script at prerender, and also tried the following in the Page_PreRender of the user control to run the desired function:

System.Web.UI.

Page page = (System.Web.UI.Page)this.Page;

MasterPage mp1 = (MasterPage)page.Master;

RadAjaxManager ajm = mp1.FindControl("RadAjaxManager1") as RadAjaxManager;

string script = String.Format("functionToRun();");

ajm.ResponseScripts.Add(script);

It finds the objects it needs within the codebehind, but then cannot find the functionToRun when it is time to run the client side function.

Is there a post or article that describes the best way to run a client side function once a dynamically loaded user control has finished loading within a RadAjaxPanel?

Thank you,

Aaron

A generic error occurred in GDI+

Hi,

I'm getting the "A generic error occurred in GDI+" error message while using the following code:

using (System.Drawing.Image originalImage = System.Drawing.Image.FromStream(upload.UploadedFiles[0].InputStream))

{

//Create empty bitmap image of original size

Bitmap tempBmp = new Bitmap(originalImage.Width, originalImage.Height);

Graphics g = Graphics.FromImage(tempBmp);

//draw the original image on tempBmp

g.DrawImage(originalImage, 0, 0, originalImage.Width, originalImage.Height);

//dispose originalImage and Graphics so the file is now free

g.Dispose();

originalImage.Dispose();

Response.ContentType = "image/jpeg";

//Save the image file to original location

tempBmp.Save(Server.MapPath("~Products/General/Imgs/Menus/" + parentSysName + "/" + productID.ToString() + "_" + upload.UploadedFiles[0].FileName), System.Drawing.Imaging.ImageFormat.Jpeg);

Can you please help me how to solve this problem?
By the way, I looked on the internet, but I didn't found anything.

The server method ... failed

I have a large dataset that I am filling a combobox with via web service. The dropdown and service work, but when I select an item from the dropdown I get "The server method MyMethod failed ", then the page processes and completes the request just like it should. Does anyone have any suggestions on how to stop the error box from popping up? or stop it from erroring at all. Any help would be great.
Thanks

Google Like Filtering

We are using Google like Filtering for the columns in a grid. The Filtering works fine for all the columns except for two columns which are displaying dates. The Format for the column in the Grid as well as the format for the date in the RadCombo(used for type ahead) is

"{0:dd-MMM-yyyy}".
Please suggest a solution.We are using a class file for this which is like your Demo File (CustomFilteringColumn.cs)

SPRadChart: Can not edit series and datasource

Installed the Sharepoint Acceleration Kit. Deployed the solution, turned the feature on and inserted the SPRadChartWebPart into a blank page on a website. I seem to be able to adjust all properties of the web part, including the color palette (which opens a pop up page). When I try and open the Series and Data Source I recieve a sharepoint error. Tracing this to the ULSTraceLog view on the WSS_Logging database I looked the error up using the correlationID and here is the stack trace:

System.NullReferenceException: Object reference not set to an instance of an object.
at SPRadChartWebPart.Layouts.SPRadChartWebPart.ManageSeries.LoadMappingValues(RadComboBox mappingsCombo)
at SPRadChartWebPart.Layouts.SPRadChartWebPart.ManageSeries.BindMappingCombos()

Anyone have any ideas why this is happening?

Thanks,

Conditionally Bound ComboBox and Exceptions

How do I handle this scenario.

I have a "Status" table which assigned StatusIDs to another table.

In my Edit form I have the Status ComboBox filtered to only show a few of those items. So 10% of my items are items NOT in this list...so when the edit form loads I get a YSOD because the items its trying to Two-way bind with isn't in the combo.

How should I handle this scenario?

            rlbSource.DataSource =  //call the function that returns a datatable.         
        
            rlbSource.DataValueField = "SYSTEM_CODE";  
        
            rlbSource.DataTextField = "SYSTEM_DESCRIPTION";          
        
            rlbSource.DataBind();

I have 3 problems here
1. Where I transfer the items from source to destination in the destination listbox the tooltip is not appearing.
2. The delete button in destination listbox is is always disabled
3. For some items in the destination the tooltip content is also displayed in the item text.

Please help to resolve these issues. Thanks in advance.
