Questions on UI for ASP.NET AJAX Forum

Hi all...
this is probably a really basic question...

what i'm trying to do is to validate whether the user has specified any files to be uploaded. I'm using just a single text box and a browse button.

I figured on using OnClientFileSelected to go to a function which will see if the file input string is zero length.

However, the event doesn't seem to be firing. Here is the RadUpload declaration:

<telerik:RadUpload InputSize="40" Width="300" ID="RadUpload1" runat="server"

ControlObjectsVisibility="None" OnClientFileSelected="checkInputFilePath" />

<telerik:RadProgressArea ID="progressArea1" runat="server" Skin="" />

The function looks like this:

function checkInputFilePath(radUpload, eventArgs)

{

alert(

'here we are');

}

The alert never happens, though an alert downstream of this, in another function, does.
Anything additionally have to be set?

Thanks in advance
david

OnValueChanging Triggers after OnError-RadnumericTextbox

Hello,

I am using both onvaluechanging and onerror client side events of RadNumeric Textbox

If user enter non-numeric values, it is only executing onerror. If you user enter numeric value but which is invalid(lets say -10), I am handling that error but after that onvaluechanging is also executing. I dont want onvaluechaing triggers after error handler.

TIA

file download functionality

Im trying to implement a file download function in a grid. The grid is controlled by an ajax manager. In the grid i have a GridButtonColumn

<telerik:GridButtonColumn ButtonType="ImageButton"

CommandName="ImageDownload" Text="Download" UniqueName="ImageDownload" ImageUrl="~/images/dnn.gif">

<HeaderStyle Width="20px" />

<ItemStyle HorizontalAlign="Center" />

</telerik:GridButtonColumn>

I then have this function that should initiate the file save dialog for users to save the selected file to their file system

protected void RadGridImages_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName.Equals("ImageDownload"))

{

			//commandargument has the physical path on the server of the selected file

DownloadImage(e.CommandArgument.ToString());

}

private void DownloadImage(string imagePath)

{

FileInfo file = new FileInfo(imagePath);

if (file.Exists)

{

Response.ClearContent();

Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);

Response.AddHeader("Content-Length", file.Length.ToString());

Response.ContentType = Studio1BusinessLayer.Helpers.ReturnExtension(file.Extension.ToLower());

Response.TransmitFile(file.FullName);

Response.End();

}

The DownloadImage method generates this error

Could not complete the operation due to error c00ce514.

Can anyone show me how to achieve a simple file download function in a radgrid ?

My problem is I ahve the ribbon bar width as 100%. But these controls do not occupy the complete width. They look very clumsy.
Is there a way to adjust each Ribbon bar tab items to take up some extra space?
Thanks

GridHyperLinkColumn - URL Issue

I am using RadGrid with a GridHyperLinkColumn. I am binding the grid on the client side. When I use the hyperlink, it seems that the hreg in the generated <a tag is a reference to the local server. This is not what is in the bound object. I have an object, with a prperty "Url", Url has the value http://google.com

<telerik:GridHyperLinkColumn HeaderText="Preplan" DataTextField="Url" DataNavigateUrlFields="Url"
Target="_blank" DataNavigateUrlFormatString="{0}" HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Left" Visible="false" AllowFiltering="false" />

Above is the markup that I am using, however the output is this:

<a target="_blank" href="/mytestsite/Home/tabid/41/language/en-US/http://google.com">http://google.com</a>

I am using DotNetNuke 5.6 with version 2010.02.0929.35 of Telerik.Web.UI.dll

Given that the text is correct and looking @ the object in the debugger, the given data string is http://google.com, I can only assume that the control is adding the relative path...

what I find interesting is that if I change the DataNavigationUrlFormattingString in the markup to be DataNavigateUrlFormatString="http://google.com" I get the expected result:
<a target="_blank" href="http://google.com">http://google.com</a>

Any thoughts on what I'm doing wrong?

An update:
It seems that if I use the property: DataNavigateUrlFormatString="http://{0}"

I get a different result, then I get either : <a href="http:http://google.com" target="_blank">http://google.com</a> or <a href="http://google.com" target="_blank">http://google.com</a>
depending on the contents of the field, if it is http://google.com then you get the former, if it's google.com then it's the latter.

Filtering issue

Hello,

I have a grid with 28 column filters. My question is: once a filter is applied, is there a way for the user to know that a particular filter is active? As there is no change in the filter icon or color (or column background), then how can the user know there is filtering in the grid and on which column(s)?
Is there any grid built-in property that allows to achieve this functionality?

Regards,
M.R.

Radgrid batchupdate issues

Hey guys,
I have an issue with batch update similar to this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/clienteditbatchupdates/defaultcs.aspx

my issue is I cant use the SqlDataSource but must use the ObjectDataSource as all Database requests goes through Stored Procedures and the stored procedure updates two tables...two update commands in the procedure.

What do I need to change in your example to get this working with an objectdatasource?

Thanks,

OrgChart binding with control template

Hi, I'm facing something strange with rad orgchart control.

I've an orgchart which i bind it with some data in the Page_PreInit, and within each node i created RadDockZone Template inside every node.

the problem is: At the last node in the orgchart it doesn't fire the InstantiateIn directly for the raddockzone template , while it's fire directly with the rest nodes except the last one, it's fire but too late , it fire after orgchart_DataBound and Page_Init and Page_Load. so this problem doesn't allow me to save the dock state in the last zone in the last node.

UPDATE : WORKING CODE IS IN THE THIRD POST PLEASE TRY IT.

Thank you.

OrgChart
