It 's simple, I only show custom edit form from web user control ( not need to bind data ). Ex: each User, I want to show a picture from picture.acsx when I click on row.

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True"

AllowPaging="True" AllowSorting="True" DataSourceID="ObjectDataSource1"

GridLines="None" Skin="Black" AllowMultiRowSelection="True"

onitemcommand="RadGrid1_ItemCommand"

AutoGenerateEditColumn="True" ShowStatusBar="True" >

<MasterTableView DataSourceID ="ObjectDataSource1" >

<EditFormSettings UserControlName="picture.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<ClientSettings AllowColumnsReorder="True" EnablePostBackOnRowClick="true">

</ClientSettings>

</telerik:RadGrid>

I had insert

<EditFormSettings UserControlName="picture.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings

>

both

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

e.Item.OwnerTableView.IsItemInserted = false;

e.Item.OwnerTableView.EditFormSettings.UserControlName = "picture.ascx";

}

But it doesn't work. What 's wrong ??? or I missed anything ??? I had read:
+ http://www.telerik.com/help/aspnet-ajax/grdcustomeditforms.html
+http://www.telerik.com/help/aspnet-ajax/grddifferenteditformsoneditandinsert.html
and demo http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx
But I don't still understand . Because I don't need bind data from grid to webusercontrol. Thanks a lot !!!

I have a RadGrid with the export to excel command enabled, and a RadFilter to filter the grid data.

When I try to export the grid to excel after applying filters, an exception occurs.

But the grid exports fine to excel if no filters are applied.

Column Widths Illogical With Static Headers

I read a lot of posts relating to column widths, but i didn't come across what i was looking for. Please forgive me if this is a repost.

I have a problem that can be quite clearly seen in the Scrolling demo here:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/scrolling/defaultcs.aspx

Turn the static headers on and off and watch the sizes of the columns.

When i have the client scrolling + static headers turned on, my grid no longer automatically sizes the columns in a reasonable way. I have a grid with a number of very small columns, and a couple of large descriptive ones. With scrolling and static headers off, it looks great. The big descriptive columns take up the majority of the space, and the smaller columns are allocated almost nothing - tight around the data.

As soon as static headers + scrolling is on, the widths are almost random. The description columns will now only get *slightly* more than others - and none of the columns are tight around the data. When the description fields are shrunk down, they wrap such that each row is now giant - it makes it basically unreadable.

Bottom Line:
Is there any possible way i can do something to maintain the great auto sizing, but still get static headers + scrolling?

-RP

EDIT: i feel like i should probably point out that i cannot hard code my column widths here - not even in percentages. The number of columns being displayed, as well as the data contained within, will vary greatly. The default auto sizing handles that perfectly, but is upset by the static + scroll.

Set Treeview Child Node Selected

Hi ALL,

        I have one treeview on left panel which will bind from database, treeview have N no. of parents and each parent have N no. of childs and each child have N number sub child.

On right side i have one textbox, when user enter some value and if it is one of treenode (Parent/Child/SubChild) then it should be selected..and on that particular selected node i need to fire treeview_nodechange event to bind right side grid.When user try to search text from textbox than treeview may be collapse or expanded, but once page load tree always be collapse.

Parent1

    Child11

    Child12

           Sub Child21

           Sub Child22

           Sub Child23

Parent2

     Child21

           Sub Child21

           Sub Child22

     Child22

Here on page load grid will be collapsed, when user try to search text like "Child11" then Parent1 should be expand and Child11 should be selected.

Same suppose user try to search "Sub Child22" than Parent2 and Child21 should be expand and "Sub Child21" should be selected

And in both case treeview_nodechange event should be fire.

I try this using

                   RadTreeView1.FindNodeByText(SearchText).Selected := true;

Its running properly for parent node only, while i am trying with any child or sub child node it will give me error and got the node as null.

Please help me on same.

Thanks

RadControls ASP/AJAX WebResource download problem/kills IIS

Hello guys,

I encounter a very weird problem; I have a page which basically kills my IIS 7.5 (Win7 X32) - requesting it takes very, very long time with a non-ending message "downloading picture nfeswr;t3e4uiowugbhhzfxdcb nvdzf.hgdx .... WebResource.axd blah...blah"; in the end IIS process blocks and I have to restart the service. Requesting the same page from the Visual Studio 2008 development server works fast and without any issues; do you have a clue about what can cause this behaviour?

Thanks,
Cris

[Solved] Nested Splitter width in Sliding Pane

I am having trouble having my splitter within a sliding pane become full width (100%) on the sliding pane expansion.
Basically, the nested splitter is remaining at the width of the Pane (RadPane6 in my example) that the Sliding Zone is nested in. Check out the pictures to see what I mean. If I Pin the sliding panel, the nested splitter's width refreshes and appears as expected.
