Hi,
I am using your splitter control..
In the top pane, i have a radgrid
In the bottom pane i have an iFrame..

What i am trying to do is, when the selectedIndex of the grid changes, the iFrame src should change.
I cannot seem to do this..

To test this, i have used (below) but this does not work..

Protected

Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged
Dim

frame1 As HtmlControl = CType(Me.FindControl("frame1"), HtmlControl)frame1.Attributes("src") = http://www.bbc.co.uk"
End Sub

However, if i place a asp:button on page and place code below in this it works ?!

Thanks
Mark

My grid aspx

<

telerik:RadGrid id="RadGrid1" runat="server" AllowPaging="True" Skin="WebBlue" AllowFilteringByColumn="True"

Width="100%" AllowSorting="True" GridLines="None" >

</RowIndicatorColumn>

</ExpandCollapseColumn>

</EditFormSettings>

</MasterTableView>

</ClientSettings>

ClientState Empty!

Hello!

I'm using a RadComboBox for ASP.NET AJAX.
I need to retrieve the value field in the Request.Form of the next page.
In order to do this, I did as told on this thred:
http://www.telerik.com/community/forums/thread/b311D-bcgmme.aspx

My problem is that the client state is filled only if the comboBox is openned by the user. If it isn't, the myCombobox_clientState stays empty.

Have an idea about this?

Thanks,

Sylvain.

RadComboBox initial value?

I currently have this.

<

asp:DropDownList ID="ddlSupportedLangs" runat="server" Style="z-index: 108; left: 300px;

position: absolute; top: 158px"

Width="150px" DataSourceID="sdsLanguages" DataTextField="LanguageName" DataValueField="LanguageID" OnSelectedIndexChanged="ddlSupportedLangs_SelectedIndexChanged" AutoPostBack="True" CausesValidation="True" ValidationGroup="langChange" AppendDataBoundItems="True" TabIndex="2">

<asp:ListItem Text="Choose Language" />

</asp:DropDownList>

I would like to have something similar excepting using the new Q1 2008 asp.net AJAX radcombo box... I tried this...

<

telerik:RadComboBox ID="ddlSupportedLangs" runat="server" Style="z-index: 108; left: 300px;

position: absolute; top: 158px"

Width="150px" DataSourceID="sdsLanguages" DataTextField="LanguageName" DataValueField="LanguageID" OnSelectedIndexChanged="ddlSupportedLangs_SelectedIndexChanged" AutoPostBack="True" ValidationGroup="langChange" AppendDataBoundItems="True" TabIndex="2">

<asp:ListItem Text="Choose Language" />

</telerik:RadComboBox>

and it failed. because <asp:ListItem > is not the right tag to use for a telerik:RadComboBox. Does anyone know how to fix this?

thanks,
Josh

Design time problem

Every time i touch the design time part of my grid it re-adds the columns but formats them incorrectly, so my control doesn't appear correctly. Once i delete these columns, it works fine.

The columns that are incorrectly put in there have Telerik.Web.UI.... instead of Telerik:.... Here is an example of what is being put in my columns:

<

Telerik.Web.UI.GridClientSelectColumn UniqueName="Select"></Telerik.Web.UI.GridClientSelectColumn>

<

Telerik.Web.UI.GridBoundColumn DataField="UserFirstName" HeaderText="First Name"

UniqueName="column2"></Telerik.Web.UI.GridBoundColumn>

<

Telerik.Web.UI.GridBoundColumn DataField="UserLastName" HeaderText="Last Name"

UniqueName="column3"></Telerik.Web.UI.GridBoundColumn>

Can someone help me fix this problem, it is irratating to keep deleting this text.

thanks

Nested databinding question

Hey everyone,

I'm trying to databind some elements to data to the Panel Bar in the following format:

Top Category 1
- sub cat 1
- sub cat 2

sub cat 1
sub cat 2

Top Category 2

But I haven't been able to find any resources in the help docs. Could anyone point me in the right direction? This is what I have so far:

                    <telerik:RadPanelBar ID="rpbMainNav" runat="server" DataTextField="Name" DataValueField="Id" OnItemDataBound="rpbMainNav_ItemDataBound" Skin="Web20" ExpandMode="SingleExpandedItem" PersistStateInCookie="True">
                        <CollapseAnimation Duration="100" Type="None" />
                        <ExpandAnimation Duration="100" Type="Linear" />
                        <ItemTemplate>
                             <%# BuildStoreList(DataBinder.Eval(Container.DataItem, "Id")) %>
                        </ItemTemplate>
                    </telerik:RadPanelBar>

Thanks in advance!

Radgrid binding with an array

I am working on a web application. My data comes in a complicated format thats why I save it to an array first and then I am creating a datatable so that I can bind it with my grid. Can you tell me how to make a datatable column a hyperlink. Following is not the actual code but logic is same
:

Code:

Dim id(2) As String
Dim desc(2) As String
'declaring an array
id(0) = "1"
id(1) = "2"
desc(0) = "Soccer"
desc(1) = "Cricket" 
Dim dt As New Data.DataTable
Dim dr As Data.DataRow

Dim i As Integer
dt.Columns.Add(New Data.DataColumn("ID", GetType(String)))
dt.Columns.Add(New Data.DataColumn("Desc", GetType(String)))

For i = 0 To (id.Length - 1)

dr = dt.NewRow
dr("ID") = id(i) 
dr("Desc") = desc(i) 
dt.Rows.Add(dr)

Next

RadGrid1.DataSource = dt
RadGrid1.DataBind()

column "ID" has values in it, e.g. 1, 2, 3, etc., and I want the grid column to show hyperlinks, e.g. "order.aspx?id=1", "order.aspx?id=2", "order.aspx?id=3", etc. How do I do that. I have to use arrays.
