I'm new do telerik-rad-controls and using your examples for learning. Following your "Input" expl. I get an "Error Rendering Control" when ever I add an label to a RadMaskedTextBox, RadNumericText etc. That's the case, even if I open your example code. However, the Label are shown OK on the web-pages when viewed by browser.

Hi,

I have grid with filtering enabled. Filtering seems to be working well except when I use '>' or '<' chars in filter box.

When I type for example "> 50%" and select "contains" from the menu it returns all the rows in datasource. It seems that  RadGrid.MasterTableView.FilterExpression is allways empty when using less than or greater than signs.

Also when I try to access the filter textbox on server-side(see below) it's empty when using those chars.



However the filter value is available in __EVENTARGUMENT hidden field.

• FireCommand:grid1$ctl00;Filter;answer|> 50%|Contains

So my question is:
Why FilterExpression is empty and how can easily fix filtering with less than and greater than signs?



By the way.. Using single apostrophe causes filtering not to work and javascript error because string is not escaped in postback function.


I'm using version 2008.2.826.35.

I have a three-tiered hierarchical grid.  I am trying to use the Window / Edit Dialog for Grid example to insert / edit records.  The example works fine for a single-tier grid, but I can't follow what I need to do to edit the command item template and the template columns at the higher levels.

I'll apologize up front.  This is my first attempt at using a hierarchical grid and I'm finding the documentation and examples very confusing and/or sparse.

My three tiers are:
  DeviceClass
    DeviceGroup
      Devices

For example, the CommandItemTemplate at the first level looks like: and the template column contains
In the code-behind, I have

This works just fine and opens the window like it should - but only for the first tier. 

What I need now is that when I click on the 'Add new Group' command at the top of the grid, I need to be able to pass the key of the parent DeviceClass, and when I click on the Edit command in the grid for a DeviceGroup, to pass both the parent DeviceClass and the current DeviceGroup.  For the 'Add...' I want the onclick code to look like 'return ShowGroupInsert('parentClass');' and on the template column, I need for the onclick to look like 'return ShowGroupEdit('parentClass','selectedGroup');'

To take this to the third level, it would be the same except for the 'Add...' I want the onclick code to look like 'return ShowDeviceInsert('parentClass','parentGroup');' and on the template column, I need for the onclick to look like 'return ShowGroupEdit('parentClass','parentGroup','parentType');'.

I have included all of my code thus far below if you need it for reference.

Many thanks!

Here is all of my aspx code. 
Likewise, here is my entire code-behind as well:

Hiya ... I seem to have the opposite issue of many in the searches I did on Grid and Width and Scrolling. Most seem to get the Browser horizontal scroll bar and want the grid to scroll not the page. With our last release we'd set our page to be a fixed width, and added a div around the Grids so that the grids could be scrolled independent of the page itself. Users are clamoring to have it back to the old way. Unfortunately, with our last release I also updated the control suite to the ASP .NET AJAX as well, and now when I remove the div we placed to scroll the grid, the page scroll does not appear.

Instead, the grid takes up as much of the screen as is available, but the times when the width of the populated columns is greater than the page width, the grid border ends, the data columns extend off the page, but no browser horizontal scroll bar appears.

Help? :)

RadControls for ASPNET AJAX Q1 2009
Microsoft Internet Explorer 7.x

Below is the grid aspx ... I've tried setting both the full RadGrid and the MasterTableView and both to 100% and no change.

This is not working for me:

 

 

<HeaderStyle HorizontalAlign="Left" />

I want to left-align the day header labels (S, M, T, W, etc.). I think the above should override the values set in any skin shouldn't it?

Thank you

 

Hi guys,

I'm pretty new to Telerik and was undering if anyone could help. Apologies if this post is in the wrong forum.
I have a RadGrid which contains several RadComboBoxes one of which enables or disables other TextBox controls on the grid at edit. When I add a new row to the RadGrid and select an entry from the ComboBox it correctly disables/enables the TextBoxes on the data entry form. When I return to the same record in the RadGrid to update the entry the TextBoxes are all enabled. Where should I be setting the TextBox state? I've tried to do this in ItemDataBound and ItemCreated.

The other issue can wait until I've got my head around this one.

Thanks for your time.

I am trying to Refresh my tree view in an update panel on the right hand side of my page when the user drag's and drop's a single or multiple nodes. on the nodeDrop event it pops up an ajax pop up and takes the quantites for the given node to be dropped, on clicking the ok button it saves it to the database and then i want it to do a refresh on the destination node to bring the new quantities through.

am using the new web service method because where loading +5000 nodes.

Protected Sub DataStoreTreeView_NodeDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs)

        Dim sourceNode As RadTreeNode = e.SourceDragNode
        Dim destNode As RadTreeNode = e.DestDragNode
        Dim dropPosition As RadTreeViewDropPosition = e.DropPosition

        Session("SourceDragNode") = sourceNode
        Session("DropPosition") = dropPosition
        Session("DestDragNode") = destNode

        If destNode IsNot Nothing Then
            If sourceNode.TreeView.SelectedNodes.Count <= 1 Then

                'Capture the Quantity
                Me.QuantityTextBox.Text = "1"
                Me.PartListQtyModalPopupExtender.Show()
                Me.OKButton.Attributes.Add("onFocus", "javascript.this.select();")
                CType(Master.FindControl("AJAXScriptManager"), ScriptManager).SetFocus(Me.OKButton)
                Me.DataStoreUpdatePanel.Update()

                PerformDragAndDrop(dropPosition, sourceNode, destNode)

            ElseIf sourceNode.TreeView.SelectedNodes.Count > 1 Then
                For Each node As RadTreeNode In sourceNode.TreeView.SelectedNodes

                   'need to sort
                Next
            End If
        End If

        destNode.Expanded = True
        sourceNode.TreeView.ClearSelectedNodes()
    End Sub

HERE IS THE OK BUTTON I WANT TO REFRESH AFTER.
 Protected Sub OKButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        'Add the dragged item as a new Part List Item

        Dim strDestValue As String = ""
        Dim intEnd As Integer
        ReDim intPLParent(0)

        If CType(Session("DestDragNode"), Telerik.Web.UI.RadTreeNode).Value = "0" Then
            intPLParent(0) = 1
        ElseIf Left(CType(Session("DestDragNode"), Telerik.Web.UI.RadTreeNode).Value, 2) = "PL" Then
            strDestValue = CType(Session("DestDragNode"), Telerik.Web.UI.RadTreeNode).Value
            intEnd = InStr(strDestValue, "~")

            If intEnd > 0 Then
                intPLParent(0) = Mid(strDestValue, 3, intEnd - 3)
            Else
                intPLParent(0) = Mid(strDestValue, 3)
            End If
        Else
            strDestValue = CType(Session("DestDragNode"), Telerik.Web.UI.RadTreeNode).Value
            intEnd = InStr(strDestValue, "~")

            If intEnd > 0 Then
                intPLParent(0) = Mid(strDestValue, 3, intEnd - 3)
            Else
                intPLParent(0) = Mid(strDestValue, 3)
            End If

        End If

        'Adds the Selected nodes from data store to the DB for creating a PartList.
        AddPartListItem(Session("SourceDragNode"), Session("DropPosition"), Session("DestDragNode"))

        If Me.PartListTreeView.Nodes(0).Nodes.Count > 0 Then
            Me.imgDeletePartList.Visible = True
        Else
            Me.imgDeletePartList.Visible = False

Hi,

I have a RadTextbox and I'd like to set the value with javascript. Here is my code:

But I get an error message Object doesn't support this property or method and if I look in detail I can't find any method like set_value in my object on textbox. I use the last Asp.Net Ajax Controls version.

Hello,

I have a RadComboBox in ListVIew control.  So I can't do:

<tel:radComboBox ... SelectedValue='<%# Bind("") %>' />

because I'm currently getting a binding error?

Why is that, and is there a remedy outside of code?  I understand I can manually assign, but it seems like I shouldn't have to tap into the ItemDataBound event just to set SelectedValue property.

Thanks.

I am using wcf service to bind rad grid(Q1 2009) via client. I am using item template column and when I change page size, I need to bind grid server side(because when I change page size just data retrieve and template column can't load).

anyone help me?
thank.
