How can I go about clearing the textbox when an entered value exceeds the min or max value instead of setting the value to the min or max?

  • Rad ASP.NET Ajax Controls Version: 2013.2.717.40
  • ASP.NET Version: 4.0.30319
  • .NET 4.0
  • Browser: IE 10

Issue: I'm trying to programmatically add ajax settings so that a asp:button click updates a RadGrid on a User Control.  The reason that this is being done programmatically is because the User Control is only visible to specific users, and an error was occurring when a user that the Control wasn't visible on used the page.

What is happening, is I get the loading pannel spinner appearing over the button and RadGrid area, but no data.  If there is a postback the data shows, or if you manually click the refresh button the data shows on the Grid.  

The code pieces in question, there is a site master with the ajaxmanager, and a proxymanager on the user control and the page.  The page checks if the user is an Admin then calls a function to set the user control to visible and does a few small things and registers the button with the grid and loading panel to the UserControl's proxymanager.  Here are the snippets of the ajax C# and the grid.

Site.MasterPage
<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="Buttons" />
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel runat="server" ID="LoadingPanel1" Skin="Default" />

UserControl.ascx
<div style="padding: 0px; border: solid 1px #000; border-top: none;">
            <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_OnNeedDataSource"
                GridLines="None" ShowStatusBar="true" AllowPaging="true" PageSize="15" AllowSorting="true"
                style="min-width:925px">
                <PagerStyle Mode="NextPrevNumericAndAdvanced" />
                <MasterTableView AutoGenerateColumns="false" CommandItemDisplay="Top" TableLayout="Fixed">
                    <CommandItemSettings ShowAddNewRecordButton="false" ShowExportToCsvButton="false"
                        ShowExportToExcelButton="false" ShowExportToPdfButton="false" ShowExportToWordButton="false"
                        ShowRefreshButton="true" />
                    <Columns>
                        <telerik:GridBoundColumn UniqueName="Date" DataField="Date" HeaderText="Date" Groupable="false" />
                        <telerik:GridBoundColumn UniqueName="Guid" DataField="Guid" HeaderText="Guid" Groupable="false" />
                        <telerik:GridBoundColumn UniqueName="Name" DataField="Name" HeaderText="Name" Groupable="false" />
                        <telerik:GridBoundColumn UniqueName="Value" DataField="Value" HeaderText="Value"
                            Groupable="false" />
                    </Columns>
                </MasterTableView>
                <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>
            </telerik:RadGrid>
        </div>
<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
        <AjaxSettings>
       </AjaxSettings>
</telerik:RadAjaxManagerProxy>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" />

Default.cs for the page that is being loaded.
protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                   if (User.IsInRole("Admin"))
                   {
                            LoadDebugInfo();
                            DebugInfoDisp.RegisterRadGrid();
                            DebugInfoDisp.RadAjaxProxy.AjaxSettings.AddAjaxSetting(button, DebugInfoDisp.RadAjaxLoadingPanel);
                            DebugInfoDisp.RadAjaxProxy.AjaxSettings.AddAjaxSetting(button, DebugInfoDisp.RadAjaxGrid);                   
                    }
            }
}

I'm still learning to use the ajax controls, I'm not sure what I have wrong.  The doc's I have used to get to this point are:

I installed the Q1 2014 package and the components are not showing in the visual studio toolbox under my framework 4.0 projects.

It is only working by default in framework 4.5 projects.

In framework 4.0, I can add them manually with the "Choose toolbox elements" option and
by referencing the 4.0 Telerik UI dll, but they are not classified by
categories as it is normally by default with telerik.

I tried resetting
the toolbox and using the Telerik toolbox configurator but it doesn't work.


Am I the only one having that problem?

Thanks
Mathieu

Does Telerik have, or does anyone know of a way to display a "book looking" viewer in ASP.net?
Like a flipbook of some sort? To display pdf's, etc.
Examples:
http://ecatalog.marykay.com/us_en-us/GetLatest.aspx?d=www.marykay.com&m=0&t=Look_Book
http://www.ismartlook.com/
http://magazine.powerblocktv.com/t/7978

I want to have the  user copy and paste data from excel to a text box, and has a button which when clocked should add the data to the datagrid. I am looking to add only one column. The grid has multiple columns, but is is only one column of data that needs to be added as new rows to the grid.
Thanks,

Hi,

Is it possible to achieve a PanelBar-like behavior with Menu?  I'm trying to use PanelBar, but horizontally, where the panes expand left and right.  If this is not an option, would it perhaps be possible to use a Splitter to emulate an accordion feel?

Thanks for the help!

Regards,
Brian Chambers

Hello there,
                   My requirement is that each row in radgrid, has a textbox and a dropdownlist inside the item template. When a  value is selected in the dropdownlist, it should populate the textbox with the selected value.
                  I tried using the dropdownlist_SelectedIndexChanged, it does populates the textbox but as not expected.For exmaple, if the radgrid contains 3 rows, ifi  i select a value in the dropdownlist at row 1, it populates the textbox at row 1 and also the textbox on other rows with the corresponding selected value of the dropdownlist in that row. I just want the action to take place in the particular row, and not in all the rows.
                 I also tried using  the client side function and made the Autopostback=false. But it doesn't work as well. $find("<%= rgUserAttendance.ClientID %>"); -->always returns null.
                 Any help on this would be much appreciated.

.ascx

<script type="text/javascript" >

 function OnSelectedIndexChange(rowindex,radGridClientID)

       {
            alert('grid found');
            var MasterTable = grid.get_masterTableView();
       }
       else 
       {
            alert('grid not found');
