File Filter only appears after upload

I found a curious issue just now. I have a RadAsyncUpload control in an ASP.NET 4.5 project, and the upload works fine, but the FileFilter doesn't seem to be showing until after I've uploaded 1 file.

To be clear:
User clicks "Choose File", the dialog popups like in the attached "before.png" screenshot
or
User clicks Cancel on that popup and clicks "Choose File" again, and it appears again like in the attached "before.png" screenshot

However if the user actually selects a file and the file is uploaded, clicking on "Choose File" again, the user is presented with a dialog as shown in the "after.png" screenshot.

Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex

Hi,

I have a grid which is similar to the following demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarativerelations/defaultcs.aspx

In this grid I have Radbuttons which toggle on/off and adjust some figuress. On each toggle button I have a javascript function which calls a web service, which calls a store proc. After this I then attempt to rebind the grid on the client side like so

var masterTable = $find( result ).get_masterTableView();

masterTable.rebind();

When I debug the project I get this error:
Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex

I'm also using the follow code to keep the nestedviews expanded, if I don't use it every change would cause the grid to collapse

void rg_ItemDataBound(object sender, GridItemEventArgs e)

{

//Expand all items using our custom storage

string[] indexes = new string[this.ExpandedStates.Keys.Count];

this.ExpandedStates.Keys.CopyTo(indexes, 0);

ArrayList arr = new ArrayList(indexes);

//Sort so we can guarantee that a parent item is expanded before any of

//its children

arr.Sort();

foreach (string key in arr)

{

bool value = (bool)this.ExpandedStates[key];

if (value)

{

rg.Items[key].Expanded = true;

}

void rg_ItemCommand(object sender, GridCommandEventArgs e)

{

//if (e.CommandName == RadGrid.ExpandCollapseCommandName && !e.Item.Expanded)

//{

if (e.CommandName == RadGrid.ExpandCollapseCommandName)

{

this.ExpandedStates[e.Item.ItemIndexHierarchical] = true;

}

private Hashtable _ordersExpandedState;

private Hashtable ExpandedStates

{

get

{

if (this._ordersExpandedState == null)

{

_ordersExpandedState = this.Session["_ordersExpandedState"] as Hashtable;

if (_ordersExpandedState == null)

{

_ordersExpandedState = new Hashtable();

this.Session["_ordersExpandedState"] = _ordersExpandedState;

}

return this._ordersExpandedState;

}

Thanks.

Cancel loading RadChart

I'm experiencing an intermittent error when cancelling the loading of a RadChart. During the load of a chart I log out of the application which causes the session to clear. After that I do a redirect to a log in page. Sometimes it works with no problem and sometimes I get an error. It is not consistent and I am testing locally on my development server.

Here is the error:

Error loading Radchart image.
You may also wish to check the ASP.NET Trace for further details.
Display stack trace?

Here are my configurations:

<add key="ChartImage_axd" value="storage=session;timeout=20;dir=~\img\chartimage" />

<system.web>
    <httpHandlers>
      <add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2011.1.413.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
    </httpHandlers>
    <httpRuntime maxRequestLength="2048000" executionTimeout="3600" />
    <sessionState timeout="60"/>

</system.web>

<system.webServer>
    <handlers>
      <add name="ChartImage_axd" verb="*" preCondition="integratedMode" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" />
    </handlers>
</system.webServer>

Do you have any ideas on how I can fix the intermittent error?

Thank you!

[Solved] Java script not working in any except IE 8 +

I have a bit of java script on a master page that is checking a user control nested inside a grid (edit mode) that ensures the user has at-least selected one of the template items in a drop-down list.
The template in the combo box contains a Check box and label....

If the user tries to submit the edited or new record, a custom validator with a client side event fire and should check to see if they user actually selected at-least 1 of the template check boxes, otherwise it displays an error and the validation control stops the post back to the server...

So if I run this in IE, I have no problems... But it does not seem to validate in chrome, safari and firefox.. I suspect it has to do with the line of code:
items.getItem(i).get_element().innerHTML.indexOf("CHECKED") > 0

Now I can get it to work if I use a server postback, but I would like to avoid a trip to the server... (see server method c# at the end of the post...)

MASTER PAGE Javascript

<script type="text/javascript">

         function ClientListBoxItemsCountValidate(source, arguments) {

            var listbox = $find(source.controltovalidate);

            var itemsCount = listbox.get_items().get_count();



            if (itemsCount < 1)

                arguments.IsValid = false;

            else if (itemsCount > 0)

                arguments.IsValid = true;

        }



        function ClientComboCountValidate(source, arguments) {

            var comboBox = $find(source.controltovalidate);

            var items = comboBox.get_items();



            for (var i = 0; i < items.get_count(); i++) {

                if (items.getItem(i).get_element().innerHTML.indexOf("CHECKED") > 0) {

                    arguments.IsValid = true;

                } else {

                    arguments.IsValid = false;

                 }

             }

        }

     </script>

ComboBox and Validator in usercontrol nested in a radgrid

<telerik:RadComboBox ID="RadComboDepartments" runat="server" DataTextField="DepartmentName"

    DataValueField="DepartmentUid" EmptyMessage="Please select" CausesValidation="True">

        <ItemTemplate>

            <asp:CheckBox ID="CheckBox" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.DepartmentName") %>' />

         </ItemTemplate>

</telerik:RadComboBox>

     <asp:CustomValidator ID="CustomValidator2" ValidateEmptyText="true" ControlToValidate="RadComboDepartments"

         Display="Dynamic" ClientValidationFunction="ClientComboCountValidate" ErrorMessage="<br />One department must be selected"

         CssClass="Error" runat="server" />

Not the desired solution: Server Side Validation...

protected void CustomValidator2_ServerValidate(object source, ServerValidateEventArgs args)

{

foreach (RadComboBoxItem item in RadComboDepartments.Items)

{

CheckBox chk = (CheckBox)item.FindControl("CheckBox");

if (chk.Checked)

{

args.IsValid = true;

return;

}

args.IsValid = false;

}
