Cannot scroll while dragging

If you have a rad grid that has say 100 items which causes the page to scroll, if you try to drag an item from the bottom of the rad grid to another rad grid that is not visible (due to the scrolling) the page does not scroll.

I know that this is a browser issue rather than a radgrid issue, but does anyone have a good workaround?

thanks

james

Windows xp to windows 7 Enterprise

Hi,
I was able to compile the code and deploy in windows xp without any problem but when I compiled in Win 7 Enterprise and deployed on to IIS server it gave the server error saying it cannot load type 'Telerik.Web.UI.DialogHandler'.
can you please explain whether this error is due to Windows 7 introducing new http module tag <add name="RadCompression" type="Telerik.Web.UI.RadCompression"/> in web.config or not?
Please find the web.config error after deployment in production server , as of now I have rolled back all the \bin\compiled items. Please help me out. Do I have to copy the app. Telerik DLL in bin folder or register it in Global assembly cache (GAC) using GACUtil.exe in prod IIS server.

Cause FileExplorer to populate node from server side

I am trying to store/retrieve a list of selected items in a file explorer control. I have been able to retrieve the checked nodes and store them without any difficulty but I am running in to a problem when I try to load the list of items back in the the explorer if they reside in nodes that have not been loaded.

Is it possible to trigger the FileExplorer control to pre-load/expand a node path from the server api?

DataFormatString . How to save raw data?

Hi guys.

I have a masked column with dataformatstring set to {0:##.###.###/####-##} and mask set to ##.###.###/####-##.The grid displays and edits the column as expected.
The problem is that I dont´t want to save the format characters to the database. I want to save the raw data 34889238000131 and not the formatted data 34.889.238/0001-31.
What´s the best way to go in this case?

Thank you.

Page flickers when using RadAjaxManagerProxy

Hello,

I have the following radGrid:

<telerik:RadGrid ID="radGrid" OnItemDataBound="radGrid_ItemDataBound" OnItemCommand="radGrid_ItemCommand">

<MasterTableView >

<Columns>

...

</Columns>

<NestedViewTemplate>

<ParteControl:ParteControl id="ctl" visible="false" runat="server"/>

</NestedViewTemplate>

</MasterTableView>

</telerik:RadGrid>

When I expand the row it fills the Usercontrol:

protected void radGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

if (e.CommandName == Telerik.Web.UI.RadGrid.ExpandCollapseCommandName)

{

if (!e.Item.Expanded)

{

Label lblId = (Label)e.Item.OwnerTableView.Items[e.Item.ItemIndex]["Info"].FindControl("lblId");

controls_partescontrol ctl = (controls_partescontrol)((Telerik.Web.UI.GridDataItem)e.Item).ChildItem.FindControl("ctl");

String[] arrValues;

String srtValues = lblId.Text.ToString();

arrValues = srtValues.Split('#');

ctl.Pre();

ctl.Visible = true;

ctl.Value = arrValues[0].ToString();

ctl.Coluna = arrValues[1].ToString();

ctl.Load();

}

In the Usercontrol I have:

<telerik:RadContextMenu ID="ctxMenu" runat="server">

<Targets>

<telerik:ContextMenuControlTarget ControlID="ajaxPanel" />

</Targets>

<Items>

<telerik:RadMenuItem>

<ItemTemplate>

<asp:LinkButton ID="lnk_1" OnClientClick="javascript: callHoldInfo(this,'Parte');" OnCommand="Menu_ItemClick" CommandArgument="0" runat="server" style="text-decoration: none !important;"></asp:LinkButton>

</ItemTemplate>

</telerik:RadMenuItem>

<telerik:RadMenuItem>

<ItemTemplate>

<asp:LinkButton ID="lnk_2" OnCommand="Menu_ItemClick" CommandArgument="1" runat="server" style="text-decoration: none !important;"></asp:LinkButton>

</ItemTemplate>

</telerik:RadMenuItem>

</Items>

</telerik:RadContextMenu>

<asp:Literal ID="ltrError" runat="server"/>

<asp:Panel runat="server" id="ajaxPanel">

</asp:Panel>

and in the Code behind of the Usercontrol:

if (this.Page != null)

{

RadAjaxManager ajaxManager = RadAjaxManager.GetCurrent(this.Page);

if (ajaxManager != null)

{

foreach (RadMenuItem item in ctxMenu.Items)

{

foreach (Control ctrl in item.Controls)

{

if (ctrl is LinkButton)

{

AjaxSetting ajaxSetting = new AjaxSetting(ajaxManager.ID);

ajaxSetting.AjaxControlID = ctrl.ID.ToString();

ajaxSetting.UpdatedControls.Add(new AjaxUpdatedControl(ltrError.ID.ToString(), "ajaxLoad"));

ajaxSetting.UpdatedControls.Add(new AjaxUpdatedControl(ajaxPanel.ID.ToString(), "ajaxLoad"));

ajaxManager.AjaxSettings.Add(ajaxSetting);

}

The first Click the pages Flickers as it could not bind the Ajax Settings. Then the Click it work normally.

I also tried to user the RadAjaxManagerProxy, but I could not make it work.

Could you please give me some advise on how to get it right...

Thank you very much,

Rod.
