Set Value on Load by FullPath

Hi

I am using RadComboBox as below

<telerik:RadComboBox ID="RadComboBox1" runat="server" Width="250px" ShowToggleImage="True"

Style="vertical-align: middle;" OnClientDropDownOpened="OnClientDropDownOpenedHandler"

EmptyMessage="Choose a destination" ExpandAnimation-Type="None" CollapseAnimation-Type="None">

<ItemTemplate>

<div id="div1">

<telerik:RadTreeView runat="server" ID="RadTreeView1" OnClientNodeClicking="nodeClicking"

Width="100%" Height="140px">

<Nodes>

</Nodes>

</telerik:RadTreeView>

</div>

</ItemTemplate>

<Items>

<telerik:RadComboBoxItem Text="" />

</Items>

</telerik:RadComboBox>

I am saving Full Path in DB like

string Path = "" ;

foreach (RadComboBoxItem myItem in RadComboBoxIn.Items)

{

RadTreeView myTree = (RadTreeView)myItem.FindControl("RadTreeView1");

Path = myTree.SelectedNode.FullPath;

}

So now onload i want to set Combo and tree to that FullPath which i saved in DB.

thanks

asp:Button versus asp:LinkButton

I haven't tried to reproduce this in a simpler ASPX page but in my solution if I use an asp:Button button then when the postback occurs the RadEditor1.Text value is correct and shows the changes that was made.

However, if I use an asp:LinkButton when it's clicked the post back does NOT show the chnages that was just made but rather shows the original content that was put into the rad editor.

Any thoughts?

Is there something about a LinkButton that causes the editor trouble? This is on .NET 4.0 using the 40 library from 2010 Q2.

Thanks,
Kevin

Drag and Drop in Hierarchy Grid?

Hi,
Put this into the context of a construction company, I need to get a system running where there is a hierarchy list of current jobs which can be expanded to show a list of machines booked to that job, which can be further expanded to show a list of operators for that machine currently working on that job. This will also have two further tables containing machines and operators which can be dragged onto jobs and machined respectively, this will then update records in a MS SQL database.
I just need to know if this is possible and if so, some guidence on how to make this posssible, as this is the first time I have used Telerik.

Many Thanks in advance,
Dan

[Solved] Updates not shown

Hi there. I think this is not telerik-specific but perhaps you might be able to help nontheless:

I have a radWindow with multiple Elements. One of them is a button, another is a "simple" radgrid
One of them is a Button that opens a new window. In that window an element can be changed in the database which is the datasource of the radgrid.

After closing that window I initiate a postback through the "OnClientClose"-Method.

Before opening that window the datasource of the radgrid had 5 Elements. After closing that window the datasource has 6 Elements (as wanted). I can see in the OnNeedsDataSource-Event that the datasource REALLY has that 6 elements. But in the frontend the new element is not shown.

I can close and reopen the window or reload it with response.redirect(response.url.toString()) but that of course kills all form entries made.

Any clue what causes that behaviour?

P.S:
Perhaps it might help to know that the NeedsDataSource-Event does not fire automaticly after closing the popup. I have to rebind manually for it to fire.

Export RadEditor Content

Hi,

I'm trying to export the content of the radeditor to PDF. I can load the radeditor without a problem ie RadEditor.Content = MyText()
I used the below on a button click event:

PrintEditor.ExportToPdf();

When I do I can the attached error. The thing is, when I copy the html code from the editor and hard code it in to the <Content></Content> tags it works fine.

Any clues?

Thanks in advance.

I want a modal popup effect to display content on a same page on which it is using DetailsView

t looks like the only content that is to be displayed in RadWindow is the content of a page that is specified in NavigateURL. That is a problem for me because what I want to display is the dynamic content that I show on the same page on which the rad window is defined.

Is it possible to display the content on the same page defined in the rad window detailsvew?
