Problem in Rad Control enable disable

[Heera]

 When combobox selectionindex changed(client side) any control enable /
disable that is work fine but when clicks on button and go to server
side then control is previous state not a selection changed state.



first rad textbox state is enable



ComboBox----> SelectionChanged ------>  rad textbox disable -----> fine

Button click event server side ----->   rad textbox state is enable that is wrong

Hi Heera,

This is the expected behavior of the RadControls. After PostBack the changes made from client side will not persist. So one suggestion is that you can make that RadTextBox as disable from server side on the Button Click itself.And another suggestion is that you can ajaxify the control, means partial postBack then RadTextBox state will persist after Button Click also.

Thanks,
Shinu.

Hi Heera,

Please have a look into the sample code snippet.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadButton1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadComboBox1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadTextBox ID="RadTextBox1" runat="server">
</telerik:RadTextBox>
<telerik:RadComboBox ID="RadComboBox1" runat="server" EmptyMessage="Select" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" />
        <telerik:RadComboBoxItem Text="Item2" />
    </Items>
</telerik:RadComboBox>
<telerik:RadButton ID="RadButton1" runat="server" Text="Click">
</telerik:RadButton>

JavaScript:

<script type="text/javascript">
    function OnClientSelectedIndexChanged(sender, args) {
        var textbox = $find("<%=RadTextBox1.ClientID %>");
        textbox.disable();
    }
</script>

Thanks,
Shinu.
