[Solved] Update validation group rad tabstrip

Hi,

We used to be able to use the following script to change the validation group each time a user clicks another tab:

function UpdateValidationGroup()
{
var tabStrip = <%=RadTabStrip1.ClientID%>;
tabStrip.ValidationGroup = tabStrip.SelectedTab.Value;
}

</script>

Currently our company is in the process of buying asp.net ajax 2009 Q1 controls and it seems that the script does not apply anymore.
Can you please help?
We have a tabstrip with four tabs. Each one with it's corresponding pageview with a set of controls. We would like to make each tab validate separately (for which we assigned a different validation group, and even a differente validation summary)
We set Radtabstrip has causesValidation=true

What are we missing here?

RadTabStrip - load on demand

Hello:

We are using Telerik v2009Q2; the business scenario is as follows:

1. RadTabStrip contains 2 RadTabs;
2. Each RadTab has 1 RadGrid;
3. Business wants data to be available only in RadTab-0 on load;
4. When user selects RadTab-1, it will load data, using AJAX;

Here is the problem we are facing:

. When user selects RadTab-1, the data in RadTab-0 gets cleared;

Note: We have tried a lot of combinations while calling AjaxSettingsCollection.AddAjaxSetting() method, but end result is always the same.

Will appreciate if a solution is provided.

Thanks .. Rohit Dehar

a s p x DOCTYPE

I have two web pages that each use the radpanelbar. Each page is setup the same as far as the panel bar. The only difference is the aspx "doctype". If I use the version HTML 4.0 doctype, then the panelbar works great. If I use the XHTML 1.0, then the bar will not work at all. In fact IE goes to lunch and I have to kill the process from the task manager.

Can anyone explain why the radpanelbar will work with this
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

but won't work with this

<!

DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

[Solved] Sort by Value

Rather than sorting my listboxes by the Text property of the ListBoxItems, I want to use the Value property.

I understand that I'm going to have to do that server-side and I have no problem with that it's just that the following seems a lot of work...

public partial class HierarchyMaintenance : System.Web.UI.Page

{

protected void ListBox_Transferred(object sender, RadListBoxTransferredEventArgs e)

{

e.DestinationListBox.Items.Sort(new ListBoxValueComparer());

}

public class ListBoxValueComparer : System.Collections.IComparer

{

int System.Collections.IComparer.Compare(Object x, Object y)

{

string xValue = (x as RadListBoxItem).Value;

string yValue = (y as RadListBoxItem).Value;

return Comparer.DefaultInvariant.Compare(xValue, yValue);

}

And if I want to sort by an attribute I would have to create a comparer for each one.

It would be nice to be just able to write something like ...

e.DestinationListBox.Items = 

e.DestinationListBox.Items.OrderBy(i=>i.Attributes[

"MyAttribute"]);

Or have I missed something?

DetailsTable with different datasources

I have a single details table with AutoGenerateColumns="true" as I would like the datasource of the details table to depend on what parent item was clicked. However, the details table seem to take structure (column setup) once (at first databind) and then stick with this structure.

Can I have one details table take structure at run time every time the details table is databound?

RadListBox still allows interaction when disabled.

Hi,

I have an edit form that has previously contained an asp CheckBoxList. I want to change it to use a RadListBox as I have done throughout the rest of the site to make apply styles consistently using AppTheme skinning.

But this edit form initially disables all controls until the user clicks an edit button which enables them. It works with all other RadControls I have in the form (RadComboBox, RadTreeView, RadMaskedTextBox and RadToolTip) but unfortunately when applied in the same way to the RadListBox the client can still check checkboxes and/or select items in the RadListBox.

The function used to disable/enable the controls is as follows:

private static void DisablePageControls(Control myControl, Boolean setEdit)

{

foreach (Control cntrl in myControl.Controls)

{

switch (cntrl.GetType().ToString())

{

case "System.Web.UI.WebControls.TextBox":

((TextBox)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadTreeView":

((RadTreeView)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadMaskedTextBox":

((RadMaskedTextBox)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadToolTip":

((RadToolTip)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadDatePicker":

((RadDatePicker)cntrl).Enabled = setEdit;

break;

case "System.Web.UI.WebControls.DropDownList":

((DropDownList)cntrl).Enabled = setEdit;

break;

case "System.Web.UI.WebControls.CheckBox":

((CheckBox)cntrl).Enabled = setEdit;

break;

case "System.Web.UI.WebControls.LinkButton":

((LinkButton)cntrl).Enabled = setEdit;

break;

case "System.Web.UI.WebControls.CheckBoxList":

((CheckBoxList)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadComboBox":

((RadComboBox)cntrl).Enabled = setEdit;

break;

case "Telerik.Web.UI.RadListBox":

((RadListBox)cntrl).Enabled = setEdit;

break;

default:

break;

}

//Call for additional controls:

if (cntrl.HasControls())

DisablePageControls(cntrl, setEdit);

}

I would also prefer the checkboxes/items to be "greyed out" or similar as is the case when the asp CheckBoxList is disabled.

Is this at all possible?

Cheers.

Struggling to style grid

Hi,

I am struggling to style a grid, I am using Telerik RadControls for ASPNET AJAX Q2 2008. I created a test project with a Default.aspx page and referenced the Telerik.Web.UI.dll and dropped a grid on the default page. Nothing more. I binded some data to the grid and the grid displayed and there was already styles associated with it. Where do these styles come from? I did not copy any of the installed skins to my web project.

The skinning seems to be different from previous versions of Telerik. In an older project that I worked on, I created a RadControls directory, and then something like Grid/Skins/Default/Styles.css. How does the directory structure have to look like for ASPNET AJAX Q2 2008. If I go to the installed directory then it would like something like C:\Program Files\Telerik\RadControls for ASPNET AJAX Q2 2008\Skins\Default.

What I am trying to say is that I would change some header text to red (to test it) and then the text still comes out black. Or I would change to make all the text bigger, then it still displays as the default text size. I have checked out the articles online and they don't help much.

Can someone please help me on the correct path to do this styling the right way?

Thanks
Brendan
