Invoking an user control which contains a radwindow and a telerik grid

Hi,

I have an web user control having a radwindow and a radgrid within it. I want to invoke this user control from multiple pages which means I want to show the popup(radwindow) from multiple pages. Could you please guide me how i cn achieve this. Now I am creating an instance of the user control in the calling form and finding the radwindow from the user control.But it is not finding the radwindow from the user control.It is giving null when I am trying to find the radwindow from the user control.

Thanks.

RadTreeView.DataBind() not working

The data binding event in this code isn't working any longer. I was testing a custom node template and using the code from this page (add and edit templates Runtime), but then removed all the code specific to the custom node template. At that point, the data stopped binding. I have added the code back, moved all of it to another page, but the data binding event doesn't seem to fire. Even with all the test code from the linked page above in my page, if I set a breakpoint in the DataBinding function it never gets hit. If I manually place a RadTreeView on the .aspx page it will display, but anything set on the server side will not.

I have checked to make sure List used to populate the tree has data, and this line (radTree.DataSource = treeNodes) works correctly. But the databind is still failing.

Any suggestions?

Thanks,
Peter

               }

Update:
From additional digging and messing around, the problem relates to converting a Guid to a string to be used as the ID field. I'm not sure why it won't accept the Guid as a string, but using an int instead of string fixes the problem. Any reason convertinting a Guid to a string would cause the data to fail to bind without any errors?

Getting values by looping through RADGrid from OnCheckedChanged

I am using RADGrid probably a little differnt than the typical - edit one item, update, save, repeat. I am using the RadGrid mainly because of its ability to maintain state on postback from the server.
I am having trouble looping through the grid from a OnCheckChange function/process.

So I have a Parent / Child Grid setup. I do have more values assigned, but for simplicity I provided the sample above. What I am doing is when the check box within the Parent or Child grid is selected I am running a routine - but I am having trouble looping through the vaules. Below is what I am attempting. Can someone assist with where I am missing?





Public Sub CheckBoxParent(ByVal sender As System.Object, ByVal e As System.EventArgs)

For Each item As GridDataItem In rParent.Items

Dim myCheckbox As CheckBox = DirectCast(item.FindControl("CheckBoxParent"), CheckBox)

Dim hAttributeID As HiddenField = DirectCast(dataItem.FindControl("hAttributeID"), HiddenField)

' Child radGrid

Dim dg As Telerik.Web.UI.RadGrid = item.FindControl("radChild")

' trying to Loop through each DataGridItem of the child grid

For Each dgItem As GridDataItem In dg.Items

Next

End Sub

<telerik:RadGrid id="rParent" runat="server" AllowMultiRowSelection="True">

<MasterTableView ShowHeader="true" AutoGenerateColumns="false">

<Columns>

<telerik:GridTemplateColumn>

<HeaderTemplate></HeaderTemplate>

<ItemTemplate>

<asp:CheckBox id="CheckBoxParent" OnCheckedChanged="findScore"

AutoPostBack="True" runat="server"></asp:CheckBox>

<%# DataBinder.Eval(Container.DataItem, "KeyID") %>

<asp:HiddenField ID="hAttributeID" runat="Server" Value='<%# DataBinder.Eval(Container.DataItem, "AttributeID") %>' />

[Solved] Alignment of wide text in RadComboBox

Hi

As per this old thread for winforms controls (http://www.telerik.com/community/forums/winforms/combobox/alignment-of-wide-text-in-radcombobox.aspx) I need to left-align the text in a combobox, rather than right-align, after it is selected.

I have this code which works for ie9, but unfortunately I need it to also work for ie7 (o I hate u ie7 so much)

<telerik:RadComboBox ID="RadComboBox1" runat="server"

Width="150px" DropDownWidth="300px"

OnClientSelectedIndexChanged="AlignLeftAfterSelectedIndexChange">

</telerik:RadComboBox>

function AlignLeftAfterSelectedIndexChange(sender) {

var input = sender.get_inputDomElement();

input.setSelectionRange(0, 0);

}

Is there a more Telerik-friendly way to do it?

Cheers
