RadTreeview Control not found in current context

I recently upgraded my UI for ASP.NET AJAX using the Telerik control panel. After doing this, my project would no longer compile. My treeview control was "Not found in current context." I was able to view the control in design view and see that it was correctly recognized. Nothing had changed, and yet the error. I've seen this before where Visual Studio somehow gets confused linking the designer and the code behind, and to solve this I've always done the following: I browse Solution Explorer to the ASPX designer page. To be clear, I delete the [My Page].aspx.designer.cs file. Then using Visual Studio, I convert the page to a web application. In Visual studio 2012, you did this by simply right clicking the ASPX file in Solution Explorer and "Convert to Web Application." In Visual Studio 2013, this option moved under the Project menu. But in Visual Studio 2015, although it remains in the same location as VS 2013, it doesn't do anything.

To resolve my "not found in current context" issue, I opened Visual Studio 2012, deleted the aspx.designer.cs file and converted the page to a web application. The new designer file popped right up. I compiled. The project built fine. Next, I opened it in VS 2015. Again I compiled it. And again it worked fine. There is a bug in VS 2015. It won't correctly build the designer file. Hopefully you won't waste hours on this like I did!

RadGrid not on first page of ASP Wizard control

Hi,

I have a RadGrid binding to a datatable which works fine when the active page of the Wizard is set to the be page of the wizard where the RadGrid is, however if the RadGrid is a wizard page that is not displaying when the page first loads the grid will not display correctly.

    
            <asp:Wizard ID="ConnectorWizard" runat="server" ActiveStepIndex="0"   
        
            <WizardSteps> 
        
                 <asp:WizardStep Title="Configuration"> 
        
                 </asp:WizardStep>                              
        
                 <asp:WizardStep Title="Devices Configuration">                             
        
                      <telerik:RadGrid ID="CTIMonitorGrid" runat="server" AutoGenerateColumns="true"> 
        
                      </telerik:RadGrid> 
        
            </WizardSteps> 
        
            </asp:Wizard>

so if i set the ActiveStepIndex to 1 it will display the grid but not if set to 0

I am populating the grid on the page load by using

    
                    DataTable dtCTIMonitors = webSess.MasterSystem.CTISystem.SelectCTIMonitorsView(3);       
        
                    CTIMonitorGrid.DataSource = dtCTIMonitors;

I have tried populating the grid each time the pageindex of the wizard control changes - but this does not seem to make any difference.

thanks
Toby

Folks, environment: UI for ASP.Net Ajax Q1 2016 With VS 2013. and using below Telerik link as a prototype in my project.

I have a sql table in SQL Server that has 2 columns, 1) Link 2) URL (i.e. https://www.google.com/ or https://www.yahoo.com/) In my edit form,
hyperlink button is pulling data (i.e. URL in Item Databound event. Works fine.

<table>

<tr>

<td style="font-size: 11px">Community District: </td>

<td>

<asp:TextBox ID="CDTextBox" Font-Size="11px" Text='<%# Bind( "CD") %>'

runat="server" TabIndex="8">

</asp:TextBox>

<asp:HyperLink ID="HyperLinkCD" Style=

Text="Link" Target="_blank"

runat="server" TabIndex="9"></asp:HyperLink>

</td>

</tr>

</table>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "Master")

{

GridEditableItem editem = (GridEditableItem)e.Item;

TextBox txtcd = (TextBox)editem.FindControl("CDTextBox");

Session["MapSource"] = "Program";

Session["Sturl"] = stnycUrlLink;

}

function Show_CDMap(seltxt)

{

var seltxtbx = seltxt.value;

alert(seltxt); ex: https://www.google.com/ or https://www.yahoo.com/

var oWind = window.radopen("ShowCDMaps.aspx", "UserListDialog");

Question about Telerik Versions

My developer license was active until 10/2012 and since then there have been many updates to the telerik products. Using the version I have available to me, there is issues with the grid rendering correctly (and even freezing) on an IE11 browser as well as it does not support the new office formats (docx, xlsx, etc). If I were to renew the license to get the latest version of telerik, will the grid issue rendering be resolved? All I see in the browser support page for the current version is that it says it supports IE8+. I just want to be sure spending the 4k for the renewal license is going to solve our issues. Thanks!

Save Grid

I have a grid I am trying to do a batch update but I need to loop through the grid and save all the values. I need to be able to get any value that was update along with values that were left alone. Is this possible? All I have been able to find is how to get new values or the old values. I need them both at the same time in a loop through the grid so when my user hits the save button I can save the entire grid to a new database table. vb.net.

Thanks,

RadGrid with EntityDataSource Filtering

I have an EntityDataSource

<asp:EntityDataSource

ID="InventoryEntityDataSource"

runat="server"

ConnectionString="name=myEntities"

DefaultContainerName="myEntities"

EnableFlattening="False"

EntitySetName="Inventory"

Select="it.[InventoryID],

it.[InventorySalesRepUserID],

it.[SalesRep_Table].[DisplayName] AS SalesRep_DisplayName,

"

EntityTypeFilter=""

OrderBy="it.[InventoryID]">

</asp:EntityDataSource>

And RadGrid

<telerik:RadGrid

ID="InventoryRadGrid"

runat="server"

AutoGenerateColumns="False"

DataSourceID="InventoryEntityDataSource"

AllowFilteringByColumn="True"

AllowPaging="True"

AllowSorting="True"

ShowGroupPanel="True"

Width="100%"

ShowFooter="True"

GroupPanelPosition="Top"

ResolveRenderMode="Classic"

CellSpacing="-1"

GridLines="Both">

<PagerStyle Mode="NextPrevAndNumeric" />

<GroupingSettings CaseSensitive="false" />

<MasterTableView

DataSourceID="InventoryEntityDataSource"

DataKeyNames="InventoryID"

EnableViewState="true"

TableLayout="Fixed">

<Columns>

<telerik:GridTemplateColumn

DataField="InventoryID"

SortExpression="InventoryID"

DataType="System.Int32"

FilterControlAltText="Filter InventoryID column"

HeaderText="Item #"

UniqueName="InventoryID"

Visible="False">

<ItemTemplate>

<asp:HyperLink

ID="HyperLink1jkl"

runat="server" Text='<%# Eval("InventoryID") %>'

</asp:HyperLink>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn

DataField="InventorySalesRepUserID"

FilterControlAltText="Filter InventorySalesRepUserID column"

HeaderText="Sales Rep ID"

UniqueName="InventorySalesRepUserID"

Visible="False"

SortExpression="InventorySalesRepUserID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn

DataField="SalesRep_DisplayName"

FilterControlAltText="Filter InventorySalesRepUserName column"

HeaderText="Sales Rep Name"

UniqueName="InventorySalesRepUserName"

Visible="False"

SortExpression="SalesRep_DisplayName">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

It loads fine and filter on radgrid also works fine when filtering InventoryID and SalesRepID but when i filter for SalesRep_DisplayName give me an error.

'SalesRep_DisplayName' is not a member of type 'myDB_Model.tblInventory' in the currently loaded schemas. Near simple identifier.
