RadGrid mobile render

New user to Telerik, here. Main question is, I have a radgrid that is about 20 columns wide w/ the ability to hide columns. In mobile render, if you attempt to hide columns using the context menu, the buttons are really wide. If you want to hide a column, you have to scroll way over uncheck it. Then you can't see what the other column names are without scrolling way back over and viewing the names.

Is there any way to set the width of the context menu so it automatically adjusts to the screen size? I did do a lot of searching on this and came up empty handed.

2) Also, in grouping, everything groups and works exactly like I would think it would, but if you ungroup anything, it throws an "Object reference not set to an instance of an object." error. It's kind of cryptic and searching for this error didn't lead me anywhere.

3) Mobile render seems a little buggy on my phone using FireFox or Chrome. Sometimes hitting the context menu icons, it will open up, group the column, and then close without me ever touching anything.

I finally got so fed up with grouping issues that I turned it off.

Outside of that, the hiding the column feature seems to work well and is at least something for a mobile user to cut down on the size of a big table.

Thanks,

Jay

How to get the text contents (box value) of AutoCompleteBox?

Hi, I need to retrieve the text contents of AutoCompleteBox in Javascript (client side).
I tried this but it just alerts me nothing (blank result):
<script>
function CheckOE() {
alert(document.getElementById('RadAutoCompleteBox1').value);
}
</script>
<telerik:RadAutoCompleteBox RenderMode="Lightweight" runat="server" ID="RadAutoCompleteBox1" ClientID="RadAutoCompleteBox1"
autopostback="true"
DataSourceID="blah" DataTextField="blah" DataValueField="blah" InputType="blah" Width="100%"
AllowCustomEntry = "false"
DropDownWidth="150px"
onfocusout="CheckOE()"
>
Any idea?
Thanks!

Blue Mockingbird Vulnerability

We upgraded the Telerik control to 2020.3.915.45 after we were hit by the Blue Mockingbird Vulnerability.

However, last weekend, we were hit again by the Blue Mockingbird Vulnerability. An ASPX file that contained this mark up was uploaded.

<asp:FileUpload ID="uplDosya" runat="server" />
<br />
<asp:Button ID="bntGonder" runat="server" Text="Submit" OnClick="btnGonder_Click" />

I've double-checked, we do have the latest version and we don only allow JPG as file extension.

Has anyone else been hit by Blue Mockingbird Vulnerability lately?

Grid change in page index, page size and filter causing full postback

I have added my rad grid inside radwindow and radwindow is place inside asp:UpdatePanel. whenever i click on the page link or change the page size or do filter or sorting, it will cause a full postback and radwindow will be closed. Opening the radwindow again, will reflect the change, like grid will reflect the filter result, etc.

how do i prevent this from happening.

my code

01.<asp:UpdatePanel ID="uPResponder" runat="server" UpdateMode="Conditional">

02. <ContentTemplate>

03. <asp:Button ID="btnOpenModal" runat="server" Text="Select user" />

04. <asp:Label ID="lblUserCount" runat="server"></asp:Label>

05. <telerik:RadWindow RenderMode="Lightweight" ID="modalPopup" runat="server" CenterIfModal="true" Width="1400px" Height="650px" Modal="true"

06. OffsetElementID="main" Style="z-index: 100001;" OnClientClose="countSelected">

07. <ContentTemplate>

08. <telerik:RadGrid RenderMode="Lightweight" ClientIDMode="AutoID" CssClass="table" AutoGenerateColumns="false" ID="gvUsers" AllowFilteringByColumn="True" AllowSorting="True" Width="100%"

09. AllowPaging="True" runat="server" AllowMultiRowSelection="true" OnPreRender="gvUsers_PreRender" OnItemCommand="gvUsers_ItemCommand" OnNeedDataSource="gvUsers_NeedDataSource">

10. <PagerStyle Position="TopAndBottom" Mode="NextPrevAndNumeric" PageSizeControlType="RadDropDownList" />

11. <MasterTableView DataKeyNames="LoginName" ShowHeader="true" EnableNoRecordsTemplate="true" ShowHeadersWhenNoRecords="true" NoMasterRecordsText="No user found">

12. <Columns>

13. <telerik:GridTemplateColumn HeaderStyle-Width="10px" AllowFiltering="false" AllowSorting="false" UniqueName="UserCheckbox">

14. <HeaderTemplate>

15. <asp:CheckBox ID="chbCheckAll" AutoPostBack="true" runat="server" OnCheckedChanged="chbAll_CheckedChanged" ClientIDMode="AutoID" />

16. </HeaderTemplate>

17. <ItemTemplate>

18. <asp:CheckBox ID="chbUser" runat="server" AutoPostBack="True" CausesValidation="false" Checked='<%# bool.Parse(Eval("isChecked").ToString()) %>'

19. OnCheckedChanged="chbUser_CheckedChanged" ClientIDMode="AutoID" />

20. </ItemTemplate>

21. </telerik:GridTemplateColumn>

22. <telerik:GridBoundColumn DataField="Name" HeaderText="Name" ShowSortIcon="true"

23. AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"

24. ShowFilterIcon="true">

25. </telerik:GridBoundColumn>

OnChange and IE

Hi !

I have to set a javascript function on a radcombobox server-side. I tried that (on the load of the page) :

    
            cmb_Pager.Attributes.Add("onchange", "Pager_ChangePageSize('" + cmb_Pager.ClientID + "', '" + Grid.ClientID + "')");

but it does'nt work in IE because the input of the combobox does'nt get the "onchange" attribute (it works perfectly in FireFox ...).

After a little search, I also tried that (on the load of the combobox) :

    
            this.Page.ClientScript.RegisterStartupScript(cmb_Pager.GetType(), 
        
                                                "blabla", 
        
                                                ";$get('" + cmb_Pager.ClientID + "_Input').onchange=function CallMethod(){Pager_ChangePageSize('" + cmb_Pager.ClientID + "', '" + Grid.ClientID + "');};",  
        
                                                true);

this time, it works on FF3 and IE7, but the "onchange" event is only fired one time for both browser.

Is there a way to set correctly in FF3 and IE7 the "onchange" of the input of the combobox ??

Thanks a lot !

Dim IdPrueba As String = String.Empty

If e.DataItem IsNot Nothing Then

IdPrueba = DirectCast(e.DataItem, Dictionary(Of String, Object))("IdPrueba").ToString()

If Not String.IsNullOrEmpty(IdPrueba) Then

'rgrdPruebaDesarrolladores.MasterTableView.Rebind()

Dim likeCondition As String = If(searchBox.Filter = SearchBoxFilter.Contains, "'%'", "")

gridDataSource.SelectParameters.Clear()

gridDataSource.SelectParameters.Add("IdPrueba", (CType(e.DataItem, Dictionary(Of String, Object)))("IdPrueba").ToString())

gridDataSource.SelectCommand =

"SELECT TOP 1 [Nombre_Sistema], [PruebaTitulo], [Nombre], [FechaPrueba], [PruebaModalidad], [PruebaStatus]  FROM [P_Pruebas] WHERE [IdPrueba] LIKE "

& likeCondition & " + @IdPrueba"

End If

End Sub



I wanted to do something similar to this example but I don't know if it can be done with Telerik
