Hello ALL,

I have developed web application using Telerik controls, on my web application i have added reference of Telerik.Web.UI (2010.1.519.35).

Application have been developed on .Net Framework 4.0, now due to some conditions i have to convert my entire application to .Net Framework 3.5, now everything converted well, when i am trying to add new page and will use any Telerik Control its running well, but when i am trying to browse my existing page, then it gives me following error.

Could not load file or assembly 'Telerik.Web.UI, Version=2008.2.826.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Please do needful to me, if i missed out anything.

Thanks
Kaushal.

Premature Highlighting

I have come accross a bit of a weird problem.

Quite simple implementation:

<telerik:RadComboBox ID="radProductList" Sort="Ascending" width="125" Runat="server" AutoPostBack="true" Font- Names="Verdana" Font-Size="7pt">

</telerik:RadComboBox>

Protected Sub radProductList_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles radProductList.Load

radProductList.AllowCustomText =

True

radProductList.MarkFirstMatch =

True

radProductList.MaxHeight = 200

radProductList.DataSource = StockList

radProductList.DataBind()

End Sub

The problem is with the highlighting. If the list contains the following:
VAL/WIRE/2
VAL/WIRE/250
VAL/WIRE/3

and we type "VAL/WIRE/2" into the combo box, the whole word is highlighted - as a result, people trying to type "VAL/WIRE/250" and up clearing the box with a "5".

I've tried various combinations of parameters, markfirstmatch being the one that I suspected was causing the problem, but no luck.

The problem only seems to be happening when the text ends with a number (don't take that as the only sittuation as it seems intermittent).

Adding Context Menus dynamically for Childnode while using Load On Demand WebService Method for Populating the Tree Node

Hi,

We are populating the tree using webservie Load On Demand method. In this we able to add child node while expanding the node. But issue is that we are not able to add Context Menus for every child node dynamically. It means we want to add context menu at the time of node creation in webservice method. We want to this way because on the context menu of every node we want to show two items. First Item of context Menu will be the name of the node and second item would be some constant value.

We able to add context menu at design time but for our requirement we want to add context menu for every node at the time of creation of node so that for each node context menu items text value will be different as in our case name of the node.

Please suggest.

Pager is not being updated

Hi!

I'm having trouble on keeping a radgrid pager updated after rebinding the table with new contents (without reloading the page). The assembly version of the control i'm using is 3.1.1.0.

On the top of the page, I have a radgrid filled with several rows using NeedDataSource.
Then, below this grid, I have another radgrid which is filtered according to the row selected on the first grid (multiple row selection is not allowed). However, the pager of the second grid is not being updated accordingly. The "total number of items" shown in the pager is never updated when I bind new contents to the second grid. For instance, the grid is showing 2 items and the pager says there are a total of 5 items.

The binding of the second grid is being done using grid2.bind() each time a new row is selected on the first grid.

Do I have to update the pager info manually? How can I solve this?

Thanks!

Rad alert in drop node handler

I have two treeviews (left and right). Our client want to prevent a user from dragging certain types of items from left or right, but to avoid confusion on their part, does not want left to have any items suppressed. I have the check in the drop handler to see if the node should not be able to be dropped, and it works. The only problem is that I'm trying to show a rad alert when I stop the drop from happening, but I cannot get it to pop:

<telerik:RadAjaxManagerProxy ID="ajxManager" runat="server">

<telerik:RadAjaxManagerProxy ID="ajxManager" runat="server">

<telerik:RadAjaxManagerProxy ID="ajxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="left">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="left" LoadingPanelID="alpT" />

<telerik:AjaxUpdatedControl ControlID="right" LoadingPanelID="alpT" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="right">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="right" LoadingPanelID="alpT" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

...

<telerik:RadTreeView ID="right" BorderColor="Black" BorderWidth="1px" OnClientContextMenuItemClicked="ContextMenuClick"

runat="server" OnNodeDrop="HandleDrop" OnNodeEdit="HandleNodeEdit" OnNodeExpand="right_NodeExpand"

EnableDragAndDrop="True" EnableDragAndDropBetweenNodes="True" Height="475px"

Width="350px" meta:resourcekey="trvResource1">

...

</telerik:RadTreeView>

Protected Sub HandleDrop(ByVal sender As Object, ByVal e As RadTreeNodeDragDropEventArgs)

...

If ShouldNotDrop Then

Dim strScript As String = "Sys.Application.add_load(function(sender, args) {if (!args.get_isPartialLoad()){radalert(""You cannot drop this here"");}});"

Telerik.Web.UI.RadAjaxManager.GetCurrent(Me).ResponseScripts.Add(strScript)

End If

...

End Sub

The code does get written to the page, I've verified this with fidler, but for some reason it is not popping up.

Input form value to filter grid page

I have created a Asp.Net 4.0 page with a RadGrid. One of the columns (ConsignorId) indicates that this record belongs to a specific Consignor. A consignor can have multiple records. I would like to have a input(textbox) where I could enter a ConsignorId and then render the page with the RadGrid with only the records selected based on the consigorid entered.

Could you refer me to an example for this? I am new to telerek.

Thank You

Check and uncheck items

Hello,

I have encountered with a strange problem.

I have a 2 list boxes, one source second a destination.
all the items have checkboxes.
Also i have 2 button: "select all","unselect all" on eatch list box header.

The code for the buttons:

function selectAllClick(sender) {

var listBox = $find(sender);

var items = listBox.get_items();

items.forEach(function(itm) { itm.set_checked(true); });

}

function unSelectAllClick(sender) {

var listBox = $find(sender);

var items = listBox.get_items();

items.forEach(function(itm) { itm.set_checked(false); });

}

The problem:

If i check an any item on one of the listboxes and then transfer it to another listbox and then i click on the unselect all button,
then the item that was transfered (the item transferd when it was checked already) still remain check. the button doens't influence
on the item.

Same problem if i reorder items and then try to check them all with the button.

any ideas?

Thanks
Oren
