I have a grid that uses a RADCombo for selection values in a row. When I select 'Edit' Ive put some code in the ItemCreated event that populates the dropdown from a custom object. This all works fine except that the dropdown list always shows the first item in the list. I need to pre-select the value in the dropdown that matches the value in the grid
eg in the grid column I have "80's"
the drop down has 2 values "70's" and "80's" and it always shows "70's" as the value when in fact is should be "80's"
How can I get the value from the cell to pre-select the value ?
Heres how im getting the drop down
eg in the grid column I have "80's"
the drop down has 2 values "70's" and "80's" and it always shows "70's" as the value when in fact is should be "80's"
How can I get the value from the cell to pre-select the value ?
Heres how im getting the drop down
| protected void RadGridSecondaryCategories_ItemDataBound(object sender, GridItemEventArgs e) |
| { |
| if (e.Item is GridEditableItem && e.Item.IsInEditMode) |
| { |
| GridEditableItem _item = (GridEditableItem)e.Item; |
| Telerik.Web.UI.RadComboBox cb = (Telerik.Web.UI.RadComboBox)_item["Category"].FindControl("RadComboBoxCategories"); |
| cb.DataSource = categorymanager.Categories(this.RadComboBoxArtistGenre.SelectedValue, this.RadComboBoxType.SelectedValue); |
| cb.DataTextField = "Category"; |
| cb.DataValueField = "Category"; |
| cb.DataBind(); |
| //TO DO: |
| //put code here to find the item in the dropdown from the database |
| TableCell cell = _item["Category"]; |
| int index = this.RadComboBoxCategories.FindItemIndexByValue();--- need to get the cell value and put it here |
| cb.SelectedIndex = index; |
| } |
| } |

Hi
I'm not sure if this post belongs here in RadCalendar or for RadDateInput.
Basically I have some RadDateInputs that share a common RadCalendar.
I know how to highlight Today's date in the RadCalendar, but is that date based on the browser's timezone?
What I need to do is programatically set the timezone from our database (like I do with culture). That way the UTC offset would be correct.
How would I go about doing this?
Kind regards

Folks could someone please elaborate on what exactly the set_checkable node method is supposed to do. It does not seem to work or achieve anything. I have just loaded the latest build 2008.2.1001.20 hoping it would but to no avail.
I wanted to be able to hide or show the node checkbox client side depending on some arbitrary criteria.
To get this to work I had to set the checkable property of all the nodes to true server side. Then using the OnClientLoad event I traverse through all the nodes and as follows.
var treeView = $find("<%=radTreeView_Level.ClientID %>");
if(treeView)
{
var nodeList = treeView.get_allNodes();
for(var i=0; i < nodeList.length; i++)
{
var node = nodeList[i];
if(node && node.get_level() > 0)
{
var chkbox = node.get_checkBoxElement();
if(node.get_checked())
{
chkbox.className = "rtChk";
}
else
{
chkbox.className = "hidden";
}
}
}
}
This works fine but seems to be a hack considering theres a set_checkable method that probably should do this for me.

After upgrading to RadControls for ASP.NET ( not ASP.NET AJAX ) my client-side validation does not perform properly. The code below puts the function into an infinite loop.
function ValidateLongitude(sender, args)
{
var newValue = String(args.NewValue);
if( newValue.charAt(0) != '-' )
{
newValue = '-' + newValue;
sender.SetValue(newValue);
}
if( newValue.length >= 4 && newValue.indexOf('.') < 0 )
{
if( newValue.substring(0,4) < -520 )
{
newValue = newValue.substring(0,3) + '.' + newValue.substring(3);
}else{
newValue = newValue.substring(0,4) + '.' + newValue.substring(4);
}
sender.SetValue(newValue);
}
if( newValue != '' && (newValue > -52 || newValue < -142 ))
{
sender.SetValue('');
}
}
Given the code below does not cause an infinite loop, can you explain why Telerik is calling the OnValueChanged every time we try to set the text box to a new value?
<html>
<head>
<script>
function BlurIt()
{
var x = document.getElementById("txtID");
x.value = "new value";
}
</script>
</head>
<body>
<form>
<input type="text" id="txtID" onblur="BlurIt();">
</form>
</body>
</html>
And upgrading to Asp.net AJAX is not option.
function ValidateLongitude(sender, args)
{
var newValue = String(args.NewValue);
if( newValue.charAt(0) != '-' )
{
newValue = '-' + newValue;
sender.SetValue(newValue);
}
if( newValue.length >= 4 && newValue.indexOf('.') < 0 )
{
if( newValue.substring(0,4) < -520 )
{
newValue = newValue.substring(0,3) + '.' + newValue.substring(3);
}else{
newValue = newValue.substring(0,4) + '.' + newValue.substring(4);

Hi,
I attached an event on OnGridDestroying that checks if the grid has been changed and asks the user to save the changes.
But i always get the error: Microsoft JScript runtime error: Sys.InvalidOperationException: ScriptLoader.loadScripts cannot be called while the ScriptLoader is already loading scripts.
I don't get this error when i attach this handler to another event like onclick.
Somebody who knows the reason?
This error only happens in IE. firefox doesn't give this error.
Thx in advance,
Glenn

I have a grid with
CommandItemDisplay
="Top"
The command bar has an insert button and a refresh button, it all seems to work ok. The problem is when there are no rows to display in the grid and I want to add one, the commandbar isnt visible so I cant add any rows !
Is there a way around this problem ? Can I have the command bar visible even when there are no rows to display in the grid ?
