Hi I am trying the set the SelectedValue in the item databound event as follows

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then

Dim editform As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

Dim combo As RadComboBox = DirectCast(editform.FindControl("RadComboBox1"), RadComboBox)

combo.SelectedValue = "123

End If

End Sub

and this works as it is, but I actually want to have the SelectedValue set to a specific column value of the selected row, but I am not sure how I can get this value at this point

Basically I am trying to replicate what happens declaratively when you have SelectedValue='<%# Bind("ColumnName") %>' but be able to intercept the value in case it does not exist in the list of values in the combobox and causes the 'Out of range' error.

Please advise !

clear Radfilter expression

ive got a function in the code behind that automatically adds an expression on a tab click on a mutli page.
but clicking back a tab simply creates another one.
how can i clear it FIRST AND THEN add the expression. i was hoping the RecreateControl would work

protected void showfilterTabs(int tab)

{

if (tab == 0)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

expr1.Value =

"";

WorkOrdersRadFilter.RootGroup.AddExpression(expr1);

WorkOrdersRadFilter.RecreateControl();

}

else if (tab == 1)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

expr1.Value =

"";

WorkOrderItemsRadFilter.RootGroup.AddExpression(expr1);

WorkOrderItemsRadFilter.RecreateControl();

}

else if (tab == 2)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

expr1.Value =

"";

SearchAllOrdersRadFilter.RootGroup.AddExpression(expr1);

SearchAllOrdersRadFilter.RecreateControl();

}

else if (tab == 3)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

expr1.Value =

"";

StorageWorkOrdersRadFilter.RootGroup.AddExpression(expr1);

StorageWorkOrdersRadFilter.RecreateControl();

}

else if (tab == 4)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

expr1.Value =

"";

SearchAllItemsRadFilter.RootGroup.AddExpression(expr1);

SearchAllItemsRadFilter.RecreateControl();

}

else if (tab == 5)

{

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERITEMDISPLAY");

expr1.Value =

"";

InventoriesRadFilter.RootGroup.AddExpression(expr1);

InventoriesRadFilter.RecreateControl();

}

[Solved] Hierarchical GridTableView RowClick getDataKeyValue

I am creating a Hierarchical grid programmatically by using a radgrid with a GridTableView. This is generated fine without issue. What I would like to do is have a row click on the gridtableview rows as well as the mastertable rows. So when I click the expand icon on the main grid, the sub rows will fire the same rowclick. Which does happen, howeveer I can not seem to get hold of the datakeyvalue of the gridtableview. For example, my javascript rowclick,

function RowClick(sender, eventArgs) {

eval(eventArgs.getDataKeyValue("ROWCLICK"));

}

RowClick fires fine, but the getDataKeyValue is always null for the sub rows (which i believe is the gridtableview). Any help with this would be much appreciated.

I have a similar issue with the contextmenu, but I guess it would be related to getting the datakeyvalue for the gridtableview.

Closing RadWindow Breaks RadGrid Cancel Button

Good afternoon. I am currently experiencing a problem. I am using the RadWindow as a dialog and allowing the user to fill out information on the dialog. When the dialog is closed, I am retrieving the values from the dialog (using the exact same technique described here:http://demos.telerik.com/aspnet-ajax/window/examples/dialogreturnvalue/defaultcs.aspx) and setting them as values on the parent browser window. The textboxes that I am populating are inside of a RadGrid. They populate just fine but if I click the Cancel button after populating them, I get the following error:

'Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: Setup.' when calling method: [nsIDOMEventListener::handleEvent]

Any help would be appreciated.

Modal window not centered when first opened.

I have a modal window that I am firing on an icon click. When the window loads, it's low and right of where it should be. If you close the window and select the icon again, the window appears in the correct position. Any clue what is going on?

[Solved] Window popup on Mouseover but then constrained to the window on MouseOut

Thanks to the forums I have been able to create a RadWindow popup when a user mouses over a RadTreeView node. But the problem I am running into is that I don't want to constrain the user to the original items surface for the mouse out to close the popup, but want to allow the user to move the mouse within the popup window to do other actions then upon mouse out close.

Hence, I want to constrain the mouse out to the new window and not the original small node surface. But I have been unable to achieve that. Where should I put the mouse out code? Here is what I have tried, note that the windowpane variable is null and never attaches the alerts.

function HandleHoverStart(sender, eventArgs) {

var node = eventArgs.get_node();

if (node != null) {

var pos = GetElementPosition(node.get_element());

var oManager = GetRadWindowManager();

var metaWindow = oManager.open(null, "DocumentMetaRadWindow");

var windowPane = document.getElementById("RadWindowWrapperElement" + metaWindow.Id);

if (windowPane != null) {

windowPane.onmouseenter = function () { alert('RadWindow enter'); };

windowPane.onmouseout = function () { alert('RadWindow out'); };

}

var X = pos.x;

var Y = pos.y;

metaWindow.MoveTo(X, Y + node.offsetHeight);

}

Close dropdown on textbox click

As you know the RadComboBox has a property called 'ShowDropDownOnTextboxClick' which opens the dropdown when the textbox is clicked. Thing is, i use a combobox without allowing custom text (i configured it to be like a standard but styled asp.net dropdown). So i need the exact opposite of the feature above. I want the dropdown to open and close when the textbox is clicked depending on the current visibility of the dropdown. Before i'm extending the ComboBox to build this in myself i thought i'd post this here since theres probably more people experiencing this. Is there a way i could toggle the dropdown on textbox-click?

Thanks in advance,

Max
