Combined max file size validation?

We have a page with a RadUpload and RadProgressArea where users can upload multiple files up to a combined maximum file size of 150MB. Is there a way to validate the size of the combined files being uploaded and prevent the page just crashing out with the "Maximum request length exceeded." error? The MaxFileSize property seems to be on the right track but only works on a per item basis instead of on the whole transaction.

Unable to combine two functionalities of RadGrid

We are working with the following two scenarios:

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/templateformupdate/defaultcs.aspx
http://demos.telerik.com/aspnet-ajax/toolbar/examples/applicationscenarios/gridcommanditem/defaultcs.aspx

These are RadToolBar as Command Item, and Form Template Edit Form. These do work for us when we try to use them separately, but they will not work together. We went down to original live example source code, and tried to combine the two without any of our own code, just original Telerik demo code, and it still does not work. For some reason when we try to edit grid item from RadToolBar, it will not open webusercontrol.

It is very easy to replicate, try modifying the following file in RadControlsExamples:

C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q3 2010\Live Demos\Grid\Examples\DataEditing\UserControlEditForm\DefaultCS.aspx

As follows:

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AllowPaging="True" CssClass="RadGrid"

AllowSorting="True" AutoGenerateColumns="False" ShowStatusBar="true" OnPreRender="RadGrid1_PreRender"

Problem with GridDropDownColumn

Hi, everybody.
Here in my company we have found a trouble with GridDropDownCollum, after we upgraded to Microsoft Dot Net Framework 4.0, this collumns only show the first value of the DataSource for each item of the DataSource, we have the same page running under the Dot Net Framework 2.0 and it works well.
This is the code that is used to populate the GridDropDownCollum:

protected void grd_list_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

GridEditManager editMan = editedItem.EditManager;

GridDropDownListColumnEditor editor = (GridDropDownListColumnEditor)(editMan.GetColumnEditor("StatusUniqueName"));

//Ativo' WHEN STATUS = 'P' THEN 'Pausado' WHEN STATUS = 'F' THEN 'Finalizado

ArrayList ds = new ArrayList();

ds.Add(new status("A", "Ativar"));

ds.Add(new status("P", "Pausar"));

ds.Add(new status("F", "Finalizar"));

//string val = oMonitor.ExecuteScalarString("select STATUS from MAILING WHERE ID = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Id"]);

string s = DataBinder.Eval(editedItem.DataItem, "StatusValue").ToString(); //the field should point to the ListValueField of the dropdown editor

editor.DataSource = ds;

editor.DataTextField = "Status";

editor.DataBind();

editor.SelectedValue = s;

}

This is the aspx code of the collun:

<telerik:GridDropDownColumn UniqueName="StatusUniqueName" ListDataMember="Status" ListTextField = "Status"

ListValueField="StatusValue" DataField="StatusValue" HeaderText="Status">

</telerik:GridDropDownColumn>

This is the class Status that you see in grd_list_ItemDataBound:

public class status

{

private string _value;

private string _text;

public status(string value, string text)

{

_value = value;

_text = text;

}

public string Status

{

get { return _text; }

set { _text = value; }

}

public string StatusValue

{

get { return _value; }

set { _value = value; }

}

};

I have tried the examples describeds in this page: http://www.telerik.com/help/aspnet-ajax/grdcustomizeconfiguregriddropdowncolumn.html,
but I had the same problem.
As I Sad I am using Microsoft Dot Net Framework 4.0 , and Rad Controls Q3 2010.
Is there a easy way to fix this problem?

Updating RadGrid when ItemCommand fired on another grid using RadAjaxManager

Ok, I have 2 RadGrids on my page as well as a number of other standard ASP.Net controls.

The first grid shows paged invoice data, displaying breif information for all invoices issued for a customer. This grid has a GridButtonColumn (defined as a LinkButton) on it that fires an event that updates the ASP.Net controls to reflect the standard invoice data (such as invoice and delivery addresses, Net, VAT and total costs, order number etc) for the selected invoice, and SHOULD update the second grid to show the line items for the invoice.

I have the page working so that I can page through the first grid (page size is set to 10 at the moment, but there could be more than 10 invoices) and even when I page through and select an invoice, the standard ASP.Net controls update ok.

However I cannot get the second grid (the one with the invoice line items in it) to update even though it is included in the UpdatedControls section of the RadAjaxManager for the first grid.

These grids aren't in users controls, but are in pages that use a masterpage. Other than that they simply reside in div's

Can anyone offer any suggestions?

AsyncFileUpload Not working properly in Safari browser

Hi,
While using the AsyncFileupload tool in safari browser it giving strange behavior. On client side validation fail 'OnClientValidationFailed', the remove link/button appears. When i am clicking on Remove button/link a file browser windows open and 'OnClientDeleting' client side event is not getting raised. The expected functionality is that the file upload text-box and button should come. I have set MaxFileInputsCount to 1 and MultipleFileSelection to false.If i choose some file in this file browser, now two rows appears. One for validation fail and second one for successfull upload.Here the remove buttons work for both the rows. This thing works fine in IE/Firefox. I am using safari 5.0.3.

Reply soon.

RadWindow size issue

I am implementing the RadWindow to facilitate poping up a window from a context menu on the RadTreeView control. Here is a snippet of the code:

<telerik:RadWindowManager ID="windowManager" runat="server" OnClientClose="Refresh">
    <Windows>
        <telerik:RadWindow runat="server" ID="window" Modal="true"></telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

The URL that opens the window consists of a few querystring arguments that have GUIDs. So as a result, the URL is very long and looks like this:

http://rddev06/_layouts/LearningVillage/FolderManagement/MoveFolder.aspx?WebID=ad89d570-0efd-4741-af92-a422ccbca129&ListID=8ca6ea04-343b-4b55-a55a-139e3c2c3787&RootFolderID=d144c25e-aee0-4457-85cf-10b8af6a5216&ItemIDs=53

It seems to me that no matter what size (width) I specify, the RadWindow ignores the size spec. initially. It seems to expand the entire window to show the full URL in the status bar of the RadWindow popup.

I have even tried setting the VisibleStatusbar property on the RadWindow to false, and it doesn't do anything.

Has anyone else experienced the same issue. Again, I'm using the Prometheus controls.

Thanks!

Window
