[Solved] GridTemplateColumn Checkbox reposted as checked Incorrectly

This is one strange bug. I have a simple RadGrid with a couple of columns, I use a GridTemplateColumn with a checkbox control for deletion, heres the markup.

<telerik:GridTemplateColumn ItemStyle-HorizontalAlign="Center" UniqueName="chkItem" ItemStyle-Width="1%">

<HeaderTemplate>

<asp:CheckBox runat="server" onclick="$('.chk-locations2 input').prop('checked', this.checked).trigger('change');" ID="chkSelectAll" />

</HeaderTemplate>

<ItemTemplate>

<asp:CheckBox CssClass="chk chk-locations2" data-value='<%#Eval("LocationID")%>' text='<%#Eval("LocationID")%>'

runat="server" ID="chkItem" Checked="false" />

</ItemTemplate>

</telerik:GridTemplateColumn>

Anyway, I have a button that does a full postback that checks for .Checked checkboxes and executes the delete operation, like this.

For Each Item As Telerik.Web.UI.GridItem In Input.Items

If Item.ItemType = GridItemType.Item Or Item.ItemType = GridItemType.AlternatingItem Then

Dim Chk As CheckBox = CType(Item.FindControl("chkItem"), CheckBox)

If Chk.Checked Then

Dim ID As String = Chk.Text

If IsNumeric(ID) Then

CallBack.Invoke(ID, Argument)

End If

Next

All works as expected, only the checked rows are deleted and since I reload the grid again, no items are checked once the page has reloaded, it all looks ok until you refresh the page again. If your grid had say 10 items and you ticked the first item and deleted it, as expected the grid now would have 9 items. If you refresh the page, a full postback is done as expected however, the first item is marked as "Checked" when it was not, so the item is then deleted and how you have 8 items despite the fact that you had not explicitly checked any item.

This seems to be a bug in the radgrid, the checkbox is shown as Checked when nobody checked it. The only solution I can see for now is to prevent a postback with Javascript by check for the no. of checked checkboxes.

Default view in RadEditor's DocManager / ImageManager

Hi,

I currently have the radEditor throughout my SharePoint application. The Document / Image Manager defaults to Gridview and thumbnails view respectively. Is there anyway to change these default views through the config.xml files? I have some picky users that keep complaining they have to switch views everytime. When uploading hundreds of images, I guess this can get tedious.

HTML image map

Hi, we're creating an HTML (not an ASP.NET control) image map dynamically from the server side into an ASP Label. An ID is assigned to each AREA tag. There is a TooltipManager on the page and the Tooltip is dynamically created when a user mouses over any hotspot on the map. This process works fine, but the Tooltip appears to the right of the image map in the same place every time. It's like the Tooltip takes the position of the image map and not the hotspot. We've looked over the demos for TooltipManager and Tooltip but both aren't quite the same and don't seem to have an issue. I've attached a screen of what it looks like and the code used for creating the Tooltip. I'm sure it's just a CSS issue but there is nothing special about the page itself, besides it being part of a MasterPage.

ASP

<telerik:RadToolTipManager ID="ttmPrinters" ShowCallout="false" RelativeTo="Element" HideEvent="ManualClose" Position="MiddleLeft" Animation="None" Width="266px" Height="394px" ContentScrolling="None" runat="server" Skin="Silk" RenderInPageRoot="true" IgnoreAltAttribute="true" Modal="true">

</telerik:RadToolTipManager>

JS

var ttm = $find("ctl00_ContentPlaceHolder1_ttmPrinters");

var tooltip = ttm.createToolTip(document.getElementById(id));

tooltip.set_content(request.d);

setTimeout(function () {

tooltip.show();

}, 10);

[Solved] Radio Button Inside EditFormType="Template"

I have a grid that lists data, and I have set the EditFormType to be "Template" and created my edit table. However, I want to be able to adjust one of the controls in my edit table to be either a RadTextBox or a RadDateTimePicker based on a different control on the same edit table (a RadioButtonList). I have an event on the RBL when a user changes the SelectedValue, so how can I swap my controls on the page based on the users actions? Or is there a better way to do it?

Is there a "common area" inside a multipage?

If this question has been asked before, my apologies for the (any) duplication.

I have two tabstrips/multipages on a single webform. The inner tabstrip/multipage contains 4 tabs each of which contains data entry controls (text boxes, combo boxes, etc.) for the same database record.

I would like to have one set of update/cancel buttons + 1 validation summary at the bottom but I cannot seem to find a "common area" either at the top or bottom of the multipage.

Is this possible? If so, is there a demo/example of this structure somewhere? Hopefully I've described my problem adequately.

Thanks in advance for any assistance!
