IIS 7 URL rewrite not working

Need to set friendly URLs for ASP classic web site running on IIS 7 .

There is this rules in my web.config

<rewrite>
        <rules>
            <rule name="chatter">
                <match url="^chatter/default.aspx?article=([0-9]+)" />
                <action type="Rewrite" url="chatter/article{R:1}.aspx" />
                <conditions>
            <add input="{QUERY_STRING}" pattern="^www\.SUB\.DOMAIN\.org$" />
                </conditions>
            </rule>
        </rules>
    </rewrite>

Nothing happens when I apply this rule. Please note there is subdomain included. Any help ?

It seems like that the condition won't match. It is looking for query string to match the domain.

ASP .net AJAX, Display pictures with method to select some of them

I need to display some pictures, between 1 and 40 or 50, and let the users select one or more of them.

Does Telerik have control that does a good job of this?

The imageGalary looks good but I don't see any way to select an image.

https://demos.telerik.com/aspnet-ajax/controls/examples/integration/listviewsliderwindowrotator/defaultcs.aspx

Any suggestions?

Simple Question can you change the selected item of all the RadComboBoxes in a RadGrid with JavaScript

Dont need to show me how. It would be appreciated, but at 1st I need to know if it is possible to on the client iterate through rows on a RadGrid and change the selected item of a RadComboBox in each row. It isnt our ultimate goal. We want when a parent row is changed for all the comboboxes in the child to get changes to the same, but the code below is a start.

I try this and no visible change is made in the grid.

for (var i = 0; i < Telerik.Web.UI.RadComboBox.ComboBoxes.length; i++) {
var combo = Telerik.Web.UI.RadComboBox.ComboBoxes[i];

var item = combo.findItemByText(changedValue);
if (item) {
item.select();
}
}

for (var i = 0; i < Telerik.Web.UI.RadComboBox.ComboBoxes.length; i++) {
                    var combo = Telerik.Web.UI.RadComboBox.ComboBoxes[i];

                    var item = combo.findItemByText(changedValue);
                    console.log(item);
                    if (item) {
                        item.select();
                    }
                }

Bound controls losing their values after modal popup

I've run into an issue using modal popups and controls on a page, and I've created a test scenario. What I'm trying to do is, when the user submits a form to save data to a database, the application first validates if everything is correct. If not, display a modal popup. This works find the first time I press "Save Data" in my test, but the 2nd time, any bound controls seem to lose their values. For example, the line -

Dim value As String = RadComboBox1.SelectedItem.Value

gives an 'Object reference not set to an instance of an object" error. Do I have to rebind every control on the page in the code-behind, or is there a better way to do this? Is this happening because I'm putting the RadWindowManager into the AjaxPanel? (I read a bit of documentation about it, but I couldn't clearly understand it).

EDIT: It also happens with another control (button) that does a postback. While rebinding does prevent the "Object Reference..." error, it loses its' selected value.

RadComboBox Width and Labels not calculating correctly With and Without Bootstrap

I have an application that uses RadComboBoxes. I have noticed several issues regarding the width and labels. I have created two testing scenarios to demonstrate some of the
behavior. Also, I am using bootstrap in my application so to demonstrate the difference
in behavior between the two, I included examples of both. Attached are the pages rendered in Chrome.

Test 1 without Bootstrap:
Aspx:

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

        <div class="container
vertical-center">

            <div class="row">

                <div class="col-sm-6
col-xs-12">

                    <telerik:RadComboBox ID="RadComboBox1" runat="server" Width="50%" Label="50% With
Label:"></telerik:RadComboBox>

                    <telerik:RadComboBox ID="RadComboBox2" runat="server" Width="100%" Label="100% With
Label:"></telerik:RadComboBox>

                    Label="100% w/o Label:
"

                    <telerik:RadComboBox ID="RadComboBox3" runat="server" Width="100%"></telerik:RadComboBox>

                    Label="50% w/o Label:
"<br />

                    <telerik:RadComboBox ID="RadComboBox4" runat="server" Width="50%"></telerik:RadComboBox>

                </div>

            </div>

        </div>

    </form>

</body>

</html>
