Grid will not bind correctly post filter (combo) selection

Hi,

I am trying to apply filter by implementing filter template. I have a radcombobox that filters the radgrid.

a) Datasource for the radgrid is a dataset defined in aspx.vb. There are 2 tables in the dataset
b) Radcombobox datasource is a datatable from the above dataset defined in aspx.vb.
c) Trying to rebind the radgrid after the radcombobox selection both in code behind and on aspx via JS.

1) using the following lines in cmbStateSelectedIndexChanged event does not rebind the grid

<code style="color: #000;">gv_MainStatusDynamic.MasterTableView.FilterExpression = e.Value<</code><code style="color: #069;font-weight: bold;">br</code><code style="color: #000;">> filterItem.FireCommandEvent("Filter", New Pair("Contains", e.Value))<</code><code style="color: #069;font-weight: bold;">br</code><code style="color: #000;">> gv_MainStatusDynamic.Rebind()</code>

2) using FilterExpression in radgrid prerender does not rebind the grid

If isFiltered Then  If rg_dynamic.MasterTableView.FilterExpression <> "0" Then  Dim filterItem As GridFilteringItem = TryCast(TryCast(sender, RadComboBox).NamingContainer, GridFilteringItem)  Dim aCombo As RadComboBox = TryCast(filterItem.FindControl("cmbState"), RadComboBox) rg_dynamic.MasterTableView.FilterExpression = Session("StateVal") rg_dynamic.MasterTableView.Rebind()  End If  End If

3) using filtering in aspx page does not rebind grid.

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server"> <script type="text/javascript"><br

>                                               function SelectedIndexChanged(sender, args)<

br> {<br

>                                                   var tableView = $find("<%# TryCast(Container, GridItem).OwnerTableView.ClientID %>");<

br

>                                                   tableView.filter("State", args.get_item().get_value(), "EqualTo");<

br> } </script> </telerik:RadScriptBlock>

In my first and second cases after I select a state and I do rg_dynamic.MasterTableView.Rebind(), the cmbState will not hold the selected value.
In my third case applying just that code to filter the grid on aspx side (that is commenting filter expression code in grid prerender and combobox selected index changed server side events) will hold the selected value.
I have the datasource available for both grid and combox box on my server side. The grid will not rebind post filtered value. I came across an example on your forum pages http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx
But it is not helping me.

I have tried to select from dataset and apply the expression to rebind the grid inside the grid pre-render event. Not sure if I am doing this right.
In the combo selected index changed event I am saving the text(name of the state) to session variable instead of stateCompID as I was doing it earlier. But the grid still does not rebind.

Dim SprocData As DataSet = GetData()  Dim items = (From p In SprocData.Tables(0).AsEnumerable()  Select New With {.ID = p.Field(Of Integer)("StateCompID"), .Name = p.Field(Of String)("State")}).ToList()  Dim filtered = items.Where(Function(x) x.Name.Contains(Session("StateVal"

))).ToList()<br>                gv_MainStatusDynamic.MasterTableView.FilterExpression = filtered.ToString<br>                gv_MainStatusDynamic.MasterTableView.Rebind()

Any help on this is appreciated.

Thanks

Here is my aspx.vb

Protected Sub rg_dynamic_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles rg_dynamic.NeedDataSource rg_dynamic.DataSource = GetData()  End Sub  Private Function GetData() As DataSet Using oConn As SqlConnection = New SqlConnection(GenConn())  End Using  End Function  Protected Sub rg_dynamic_ItemCreated(sender As Object, e As GridItemEventArgs) Handles rg_dynamic.ItemCreated  If TypeOf e.Item Is GridFilteringItem Then  Dim filterItem As GridFilteringItem = DirectCast(e.Item, GridFilteringItem)  Dim cmbState As RadComboBox = DirectCast(filterItem("State").FindControl("cmbState"), RadComboBox) cmbState.SelectedValue = e.Item.OwnerTableView.GetColumn("State").CurrentFilterValue RefreshStateCombo(cmbState)  End If  End Sub  Protected Sub RefreshStateCombo(ByVal stCombo As RadComboBox)  Dim SprocData As DataSet = GetData()  Dim oDbDS As New DataBaseUtils2  Dim StateDate As DataView = SprocData.Tables(0).DefaultView  Dim dtStatedata As

DataTable = StateDate.Table()<br>        stCombo.DataSource = StateDate<br>        stCombo.DataTextField = dtStatedata.Columns(1).ToString() <br>        stCombo.DataValueField = dtStatedata.Columns(0).ToString()  <br>

End Sub  Protected Sub rg_dynamic_PreRender(sender As Object, e As EventArgs) Handles rg_dynamic.PreRender  If isFiltered Then  If rg_dynamic.MasterTableView.FilterExpression <> "0" Then  Dim filterItem As GridFilteringItem = TryCast(TryCast(sender, RadComboBox).NamingContainer, GridFilteringItem)  Dim aCombo As RadComboBox = TryCast(filterItem.FindControl("cmbState"), RadComboBox) rg_dynamic.MasterTableView.FilterExpression = Session("StateVal") rg_dynamic.MasterTableView.Rebind()  End If  End If  End Sub  Private isFiltered As Boolean = false  Protected Sub cmbStateSelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs)  If e.Value <> "0" Then isFiltered = True Session("StateVal") = e.Value  End If 

'Dim filterItem As GridFilteringItem = TryCast(TryCast(sender, RadComboBox).NamingContainer, GridFilteringItem)<br>        'filterItem.OwnerTableView.GetColumn("StateCompID").CurrentFilterValue = e.Value ''CAPTURE THIS VALUE in a property<br>        'rg_dynamic.MasterTableView.FilterExpression = e.Value<br>        'filterItem.FireCommandEvent("Filter", New Pair("EqualTo", e.Value))<br>        ' rg_dynamic.Rebind()<br>    End Sub

File is uploaded instantly and OnFileUploaded event not firing

I am trying to use the RadAsyncUpload to upload a file, the file does get uploaded but it is uploaded as soon as it is selected and the OnFileUploaded event is never fired. I have tried everything in the following links and none have worked: link1, link2, link3, link4. The .aspx file is quite large and so I will try to give all the important information without showing all lines of html. The uploader is in a radpane whose visibility is set to false until the user makes a selection, that radpane is nested within mutiple radpanes and splitters, all of which are inside an asp Panel. I am using the RadAjaxManager as well and I have added the uploader, panel and the postback trigger button to in an attempt to make it work. Not sure if this will make a difference but the uploader is also not uploading to the TargetFolder.

Here is the requestStart function to cause the postback (I do have the ClientEvents OnRequestStart in the ajaxManager):

<telerik:RadCodeBlock ID="rcb1" runat="server">

<script type="text/javascript">

function requestStart(target, arguments) {

if (arguments.get_eventTarget().indexOf("btnUpload") > -1) {

arguments.set_enableAjax(false);

}

if (arguments.get_eventTarget().indexOf("rauFile") > -1) {

arguments.set_enableAjax(false);

arguments.set_cancel(true);

}

</script>

</telerik:RadCodeBlock>

Here is the html for the radasyncupload and the postbacktrigger button:

<telerik:RadAsyncUpload ID="rauFile" runat="server" AllowedFileExtensions=".xls, .xlsx" HideFileInput="true" PostbackTriggers="btnUpload" MaxFileInputsCount="1" OnFileUploaded="rauFile_FileUploaded" TargetFolder="~/Uploads/Run Matrix/" />

<telerik:RadButton ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />

Phantom vertical line seen only in Google Chrome

We're using Google Chrome browser version 58.0.3029.110 (64-bit) in Windows 10.

A phantom vertical line appears when using the telerik:RadTabStrip. Please see the attached image. This doesn't appear in other major browsers, such as Edge, FireFox, or Safari.

Upgrading from a 2009 version of Telerik UI

I have an application that was made in 2009 and runs on .NET 3.5. It uses the 2009.3.1103.35 version of the Telerik.Web.UI.dll. The project relies heavily on that Rad user controls and AJAX managers, etc..

However, I have to upgrade the project to at least 4.0. The version of the installed Telerik does not support 4.0... So, I would also need to upgrade my version of Telerik, as well as buy a new license since the application was originally built by a third party.

I was curious as to what the process of upgrading from the 2009 version of Telerik to a more recent version would look like? Would it be simple or would it involve extensive work?
