about var tree = $find("<%= RadTreeView1.ClientID %>");

In javascript in order to get the client-side instance of Telerik Object it's possible to use:

var tree = $find("<%= RadTreeView1.ClientID %>"

But how to do the same by means of vbscript?

RadUpload File Lost on Postback

Hello,

I have a RadUpload control on a web form. However, I'm storing a lot of additional information with regard to the file that is being uploaded in additional text boxes, combo boxes, etc. Some of these values cause the page to post back, which normally would be fine because all of the information get's put into ViewState. However, every time the page posts back, the Upload control loses the file that was selected and I have to select the file again.

Is there a way to preserve the value of the file selected between post backs?

Thanks,
Warren

[Solved] How to access and set visibility of child controls from ClientSelectedIndexChanged event handler?

I have a RadListBox, where, inside the ItemTemplate, I have a RadComboBox, another RadComboBox, and a RadTextBox. Based on the selected value in the first RadComboBox (captured in ClientSelectedIndexChanged), I want to show or hide the other controls. That is, if the value in the first RadComboBox is "apple," I want to show the second RadComboBox and hide the RadTextBox. However, if the value in the first RadComboBox is "banana," I want to hide the second RadComboBox and show the RadTextBox.

What is the normal way of doing this from this event handler?

Thanks

Conditional formatting of the row.

Hello,

I'm trying to implement dynamic conditional formatting in the RadGrid. The conditional formatting settings are supplied dynamically as a collection of filters that I need to apply on the server and have the grid display the corresponding styling. I can't find any relevant documentation that could enable me to do so. There's this example:

protected void RadGrid1_ItemDataBound(object sender, Telerik.WebControls.GridItemEventArgs e)

{

//Is it a GridDataItem

if (e.Item is GridDataItem)

{

//Get the instance of the right type

GridDataItem dataBoundItem = e.Item as GridDataItem;

//Check the formatting condition

if (int.Parse(dataBoundItem["Size"].Text) > 100 )

{

dataBoundItem[ "Received"].ForeColor = Color.Red;

dataBoundItem[ "Received"].Font.Bold = true;

//Customize more...

}

But the problem is that I don't know if it will be one boolean clause or three. So the condition may be "Title == "Home"" or it could be "Title == Home AND Amount <= 10" So I need to be able to dynamically build out the filter conditions.

I tried using the OnRowDataBound client side event and construct the javascript dynamically in C#, but the event is not firing because I'm not binding on the client side, but in the OnNeedDataSource event.

Any ideas?

[Solved] sender.get_masterTableView() returns null in GridDestroying after .NET 4.0 upgrade

I have a RadGrid (along with a RadAjaxManager). The version is 2010.1.415.35

There is a 'Refresh' button on the page, which eventually calls __doPostBack.
Everything was working fine until I upgraded the website from .NET 3.5 to 4.0.
But now, after the AJAX call sender.get_masterTableView() returns null in the GridDestroying function.

Is there a fix for this version?
