$find cannot find radajaxmanager

there are numerous but unhelpful threads about $find() failing to find radajaxmanager, a problem i am currently encountering after several weeks of successful operation. what must be true in order for $find() to find radajaxmanager???

i have a page with an ajaxcontrols toolkit tab. the first tab contains a grid whose rows can be selected (only 1 at a time). above the tab control is a radajaxmanager. the client onrowselected event is as follows:

<script type="text/javascript" id="telerikClientEvents1">

//<![CDATA[

function SaleEventsRadGrid_OnRowSelected(sender,args)

{

//find and set some other controls. then do the following to rebind a grid on another tab:

$find("<=RadAjaxManager1.ClientID%>").ajaxRequest();

}

//]]>

</script>

Error: Unable to get value of the property 'ajaxRequest': object is null or undefined

why can't $find() find radajaxmanager even though it can find any other control i wish to find? the aspx page uses a master page containing radscriptmanager.

Enable EnableRangeFiltering With Programmatic Client Side Binding

I'm using https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/programmatic/defaultvb.aspx?show-source=true as an example for client side binding, however for columns with datetime data type I can't get the filter to work properly when EnableRangeFiltering is enabled. Does anyone have an example to make the BuildParameter correct, in which case GridKnownFunction.Between is used and the values are passed in expression.FieldValue separated by space. Example: "01/01/2021 07/01/2021". Thanks

Displaying the same grid on two different pages

I have a RadGrid being populated and displaying but the client needs a condition format for the grid to display new columns while hiding others. Is there a way to display the same grid on two different pages with different data source?

How to determine which button is clicked in a group

We've set up a group of buttons with the toggle type set to radio and the button type set to standard. Basically, one and only one button can be activated at a time. We can't figure out how to determine which button was actually pressed though. When we we cycle through the button controls, there is no setting we can test to see if it's currently the one pressed. We tried to wire up an event but we lose context on postback. How can we do this?

RadComboBox are going to be the Death of me

I have the following Combobox

<telerik:RadComboBox ID="cbAcctType" runat="server" DataValueField="ACCT_TYPE_ID" DataTextField="acct_code" RenderMode="Classic"

AutoPostBack="True" CausesValidation="False" Width="100%" DropDownWidth="400px" HighlightTemplatedItems="True"

InputCssClass="required_cb" EnableLoadOnDemand="true" AppendDataBoundItems="True">

<ItemTemplate>

<asp:Table runat="server" CellPadding="0" CellSpacing="0" Width="100%" GridLines="None">

<asp:TableRow>

<asp:TableCell Width="30%">

<%# DataBinder.Eval(Container.DataItem, "acct_code") %>

</asp:TableCell>

<asp:TableCell Width="70%">

<%# DataBinder.Eval(Container.DataItem, "acct_description") %>

</asp:TableCell>

</asp:TableRow>

</asp:Table>

</ItemTemplate>

</telerik:RadComboBox>

and I bind it with the following code:

cbAcctType.DataSource = ds.Tables("AcctType")

cbAcctType.DataBind()

Sometimes the code associated with an account will expire and no longer be available in the available list, but it still exists so I have to individually retrieve it and add it to the combobox list. Here is my code for that process

Dim oItem As New RadComboBoxItem

oItem.DataItem = ds.Tables(0).Rows(0)

oItem.Value = ds.Tables(0).Rows(0).Item("ACCT_TYPE_ID").ToString

oItem.Text = ds.Tables(0).Rows(0).Item("acct_code").ToString

oItem.Selected = True

cbAcctType.Items.Add(oItem)

And that's where the wheels come off. The items is there but only sort of. It will get selected but there is no items in the list. and it usually throws and ASPX page error the <%# DataBinder.Eval(Container.DataItem, "acct_code") %> doesn't exist.

What is the piece of the puzzle that's missing? I have tried it with oItem.DataBind() and that doesn't solve things.

Build Help File or Knowledge Base

Looking for advice on how you have used Telerik tools to build help files for web apps without building individual pages. Trying to find a way to build it into a database etc versus just a static hard coded page.

Load RadComboBox on SelectedIndexChange of Second RadComboBox in EditFormSettings

I am trying to populate a RadComboBox dynamically based on the selected of another RadComboBox in EditFormSettings.

Here is a code snippet of what I'm trying to do:

<telerik:RadGrid RenderMode="Lightweight" ID="rgEmployeeAssignments" Width="100%" AllowFilteringByColumn="True"
OnItemCommand="rgEmployeeAssignments_ItemCommand" AllowSorting="True" AllowPaging="True" PageSize="20" runat="server" AutoGenerateColumns="False"

<MasterTableView DataKeyNames="EmployeeID" ClientDataKeyNames="EmployeeID" TableLayout="Fixed">

SelectedValue='<%# TryCast(Container, GridItem).OwnerTableView.GetColumn("WORKGROUP").CurrentFilterValue %>'
runat="server" OnClientSelectedIndexChanged="TitleIndexChanged">
<Items>
<telerik:RadComboBoxItem Text="All" />
</Items>
</telerik:RadComboBox>
<telerik:RadScriptBlock ID="rsbWorkGroup" runat="server">
<script type="text/javascript">
function TitleIndexChanged(sender, args) {
var tableView = $find("<%# TryCast(Container, GridItem).OwnerTableView.ClientID %>");
tableView.filter("WORKGROUP", args.get_item().get_value(), "EqualTo");
}
</script>
</telerik:RadScriptBlock>
</FilterTemplate>
</telerik:GridBoundColumn>

</tr>
<tr>
<td>

</td>
</tr>
</table>
</FormTemplate>
</EditFormSettings>
</MasterTableView>
<PagerStyle Mode="NextPrevAndNumeric" PagerTextFormat="" />
</telerik:RadGrid>

My Codebehind for the IndexChanged event is:

Protected Sub rcbWorkGroup_IndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs)
Dim x = 1

End Sub

I will hit the breakpoint when the workgroup is selected but I do not know how to fill the workgroupoptions combo in the SelectedIndexChanged sub.
