Trying to use the ContextMenu with the ListBox

I'm using the RadListBox as is shown in the screenshot. Through JavaScript I'm able to correctly distinguish between single and double left clicks.

Looking at my code (about a year old now), I see that I had tried introducing the RadContextMenu to the RadListBox but had disabled it. I don't think it was quite working ideally. But my client is hoping I could introduce a context menu. Essentially what I'd like the user to be able to do is right click over top of any of the RadListBox items and a simple context menu appear. The *problem* is that I don't know know how to determine which RadListBox item is being right clicked upon.

It's important to understand that I do NOT want to force the user to first left click a RadListBox item. They should just be able to immediately right click over top of it.

So how do I determine which RadListBox item they're right clicking over top of?

Filter button has column header menu after postback

I'm having some trouble with filter menus. When I first load the page, I don't have menus when I click the filter buttons.

I then filter using the CurrentFilterFunction="Contains" setting and pressing <tab>, a postback occurs, and now my filter buttons have the column header menus (Sort Ascending..., Group By, Best fit, etc.)

Any ideas why or what I can do to get and keep the proper filter menus?

C#

protected override void OnPreRender(System.EventArgs e)

{

// ... Control setup unrelated to RadGrid1

// Test filtering

bool Filter = true;

if (Filter)

{

RadGrid1.AllowFilteringByColumn = Filter;

RadGrid1.MasterTableView.AllowFilteringByColumn = Filter;

}

}



// I've also got handlers for these, but they don't setup filtering:



            RadGrid1.PreRender += RadGrid1_PreRender;

            RadGrid1.ItemCreated += RadGrid1_ItemCreated;

            RadGrid1.ItemDataBound += RadGrid1_ItemDataBound;

            RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

            RadGrid1.GroupsChanging += RadGrid1_GroupsChanging;

Exporting Headers to Excel & CSV

Hello,

I am using RadGrid (version 2014.1.403.45) and I need to export a header to PDF, Excel, and CSV. For PDF, this is accomplished easily, by using the "Pdf-PageTitle" property on the <ExportSettings>. Is there something similar for Excel and CSV? If not, is there a workaround?

Thanks,
Steve

[Solved] Reading DataTable when I'm done with TreeView

We're using the RadTreeView to show a hierarchical structure.

Since our data does not follow the format required, (parentid, id, text), we are creating a datatable on the fly, adding values (and additional attributes) and binding. Now the user can add more information to the tree.

When the user is done, we want to access all the data from the tree, convert it to our format and save it back to the database.

The question is: can I access the datatable as it is? For every edit, I'm adding the required data to the datatable (using node attributes).

If not, what is the best way to get all the data out and write it in my required format?

Thanks in Advance.

[Solved] What If Ajaxified Control and Updated Control Are The Same...

In the AddAjaxSetting(Control ajaxifiedControl, Control updatedControl) method, is it ok for both Control arguments to be the same object? For example:

radAjaxMgr1.AjaxSettings.AddAjaxSetting(myCustomEditor, myCustomEditor);

myCustomEditor is of the type WebControl. It looks like myCustomEditor is going to respond to some client-side action on itself, but is that allowed by the RadAjaxManager?

Thanks!

RadGrid and CustomValidator with AJAX

Hi,

I'm using a radgrid with a templated edit form and popup edit mode. Most of my validators are requireduiredfieldvalidators but one of my fields need to be validated agains the database. I therefore need to use a CustomValidator which is OK but if I do the validation server side then the error is not shown at the same time as the client side validator errors in the validationsummary.

Therefore I'm trying to call an AJAX method in the custom validator:

ClientValidationFunction="InitiateAsyncRequest('this.id')";

This calls the a server side method:

public void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

In this method I would like to perform the validation and then set the IsValid flag on the customervalidator. The problem I am having is finding the CustomValidator control in the AjaxRequest method on the server. The SelectedItems property on the RadGrid is empy and RadGrid.FindControl("Customvalidator1") returns null. Is this possible? Or is there an easier way to do this?

Thanks, Stuart

Manipulate InPlace Insert Item Text Value Based Upon SelectedIndexChanged Event of InPlace RadComboBox

I have a RadGrid which uses InPlace editing, and this grid contains a RadComboBox and a RadTextBox. When the user changes the text choice of the RadTextBox, the value behind the choice is used to retrieve data using AutoPostBack, and the returned data needs to update the text value of the RadTextBox.

Here's what the .aspx code looks like:

<telerik:RadGrid ID="rgvMsgElementToMsgTemplate" runat="server" GridLines="None" AutoGenerateColumns="false" MasterTableView-NoMasterRecordsText="No Records To Display">

<MasterTableView CommandItemDisplay="Top" NoDetailRecordsText="No Records To Display" EditMode="InPlace">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn">

<HeaderStyle Width="50px" />

</telerik:GridEditCommandColumn>

<telerik:GridTemplateColumn DataField="TMPLT_NM" HeaderText="Template" UniqueName="TMPLT_NM">

<HeaderStyle Width="200px" />

<ItemTemplate>

<asp:LinkButton ID="lblMessageTemplate" CommandName="EDIT" runat="server"

Text='<%#Container.DataItem("TMPLT_NM")%>' />

</ItemTemplate>

<InsertItemTemplate>

<telerik:RadComboBox runat="server" ID="rcbTemplate" DataTextField="TMPLT_NM" DataValueField="AMCAT_ID" Width="190px" DropDownAutoWidth="Enabled"

OnSelectedIndexChanged="rcbTemplate_SelectedIndexChanged" AutoPostBack="true"></telerik:RadComboBox>

<asp:RequiredFieldValidator ID="rcbTemplateValidator" CssClass="redreq" ControlToValidate="rcbTemplate" InitialValue="-- Select an Item --" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

</InsertItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Version Id" UniqueName="TMPLT_VRS_ID" DataField="TMPLT_VRS_ID">

<HeaderStyle Width="50px" />

<ItemTemplate>

<%# Eval("TMPLT_VRS_ID")%>

</ItemTemplate>

<InsertItemTemplate>

<telerik:RadTextBox runat="server" ID="rtbVersion" DataField="TMPLT_VRS_ID" readonly="true" Width="50px"></telerik:RadTextBox>

</InsertItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

My issue is that inside the SelectedIndexChanged event, I don't know how to access the InsertItem(s) defined in the .aspx from within this event. I have tried to use the NamingContainer, EditItems collection, the GetInsertItems() function, using a Try/DirectCast to FindControl to no avail.

Public Sub rcbTemplate_SelectedIndexChanged(sender As Object, e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

' Somewhere in here I need to get to the each item inside the InPlace edit section of the grid...

End Sub

Is this even possible?

Thanks.

Jim

RadGrid FilterMenu causing javascript error, not sure if it is a bug

2014.2.724.45
When in Grid Init event:
GridID.FilterMenu.Items.Clear()

With filtering active on a column, clicking the filter button generates this javascript error:

Uncaught TypeError: Cannot read property `_linkElement` of undefined

Referring to this code:
Type.registerNamespace("Telerik.Web.UI");
Telerik.Web.UI.GridColumn=function(a){Telerik.Web.UI.GridColumn.initializeBase(this,[a]);
.....
var h=this._filterMenu.get_focusedItem()||this._filterMenu.get_items().getItem(0);
if(h._linkElement){h._linkElement.focus(); <-- err line. 6623
}else{if(h._templateElement){h._templateElement.focus();

The line above does not appear in the the version 2014.1.403.45 nor does the same error happen.

I have to add
<ClientEvents OnFilterMenuShowing="RadGrid_DisableFilterMenu" />

function RadGrid_DisableFilterMenu(sender, args) {
args.set_cancel(true)
}
