In my grid if I set the DataKeyName field ReadOnly to "true" so it cannot be edited when I click a row to enter edit mode I get this error,
Unhandled exception at line 885, column 13 in http://localhost:59512/ScriptResource.axd?d=j9g8KwFmyomCksH8Wgu8D921e69mOXBSgcRNM_TYTpo8fsl9bB8knaOk3eJy7i5Vsb6eNonPd3OAqh2MBYPCrNV52HuzPz2Aa-oyIrtDhXd-WOK9m-TImS6nd3inJNNp1xw6jnQGAvJnKfjurTJifqmDUI5njfi6aRYOERJTLDf7VE7Tms_H7Dr6lpjgTT2J0&t=6119e399

0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Value cannot be null.

Parameter name: g

If I do not set the DataKeyName field ReadOnly="true" I do not get this error, but the field is shown and editable in the edit popup.

Setting a value of the textbox

Hi,
I have a following problem. First code:

<telerik:RadPanelBar runat="server" ID="RadPanelBar2" ExpandMode="SingleExpandedItem" Width="100%">

<Items>

<telerik:RadPanelItem ImageUrl="~/Images/Att.png" Text="MojAtak" runat="server" Expanded="True">

<Items>

<telerik:RadPanelItem runat="server">

<ItemTemplate>

<asp:TextBox ID="ReportBox" class="text" runat="server" Style="height: 99%; width: 98%; font-size: 9px; border-style: none;" TextMode="MultiLine" onkeyup="javascript: czytaj();"></asp:TextBox>

<asp:TextBox ID="txtKto" runat="server" class="text" Height="14px" Style="width: 140px;" Font-Size="Small" BackColor="#CCFFFF" Font-Italic="True"></asp:TextBox>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem ImageUrl="~/Images/Cone.png" Text="Outbox" runat="server">

<Items>

<telerik:RadPanelItem runat="server">

<ItemTemplate>

<asp:TextBox ID="txtKogoS" runat="server" class="text" Height="14px" Style="width: 140px;" Font-Size="Small" ReadOnly="True" BackColor="#CCFFFF" Font-Italic="True"></asp:TextBox>

<asp:TextBox ID="txtDataS" runat="server" class="text" Height="14px" Style="width: 140px;" Font-Size="Small" ReadOnly="True" BackColor="#CCFFFF" Font-Italic="True"></asp:TextBox>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

var ReportBox = '<%=((TextBox)RadPanelBar2.Items[0].Items[0].FindControl("ReportBox")).ClientID%>';

var KtoBox = '<%=((TextBox)RadPanelBar2.Items[0].Items[0].FindControl("txtKto")).ClientID%>';

function czytaj() {

alert($get(ReportBox).value);

var raport = $get(ReportBox).value;

if (raport.search("ygrał") > 0 || raport.search("z walki:") > 0 || raport.search("Remis") >= 0) {

alert("Kto");

//kto

var k1 = raport.indexOf("w.", 0);

var wynikS = raport.substring(k1 + 3);

var k2 = wynikS.indexOf("otrzyma", 0);

var kto = wynikS.substring(0, k2 - 1);

alert(kto);

alert(KtoBox);

} else {

alert("!!!!");

}

</script>

</telerik:RadScriptBlock>

onkeyup - I can access whatever user entered in the ‘ReportBox’ but I can’t update ‘txtKto’.

If anyone have any suggestion please go ahead. Oh and please keep in mind I'm a rookie.

Thank you

We have been using Rad Async upload control for file uploading in ASP.NET Web application for one of our clients. Rad Async upload control works fine for Chrome, Firefox and IE10. But with IE9 or below a strange javascript error is encountered saying

"DOM Script bridge is disabled".

This happens while uploading the file to the server. Can you please guide me through this issue?

Thanks

Load on demand not working

The load on demand for the combobox is not working once I move the page to the shared host. It works fine while testing it in Visual Studio.
Up on the shared host, when I click on the combobox, it drops down showing the items in the box. But, as soon as I type a single letter, the "Loading..." message appears and it just sits there. Even if I type the first letter of the first item in the box, it will show the loading message and then do nothing.

I tried both loading from server side, and also by setting the EnableAutomaticLoadOnDemand="true". The latter doesn't even load the list.

This will at least display the list:

<telerik:RadComboBox ID="CustomerSearch" runat="server" Width="180" Height="160"

MarkFirstMatch="true" AllowCustomText="true" CssClass="CustomerSearch"

EnableLoadOnDemand="true" EnableVirtualScrolling="true" OnItemsRequested="CustomerSearch_ItemsRequested"

OnClientSelectedIndexChanged="searchnav" EmptyMessage="Select a customer" DataSourceID="dsCustomer" DataTextField="CustomerName"

DataValueField="NavPath" BackColor="White" Skin="Forest" />

<asp:SqlDataSource ID="dsCustomer" runat="server"

SelectCommand="CustomerSearchName" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function searchnav(sender, args) {

var iframe = document.getElementById('ctl00_iMainPages');

iframe.src = sender.get_value();

}

</script>

</telerik:RadScriptBlock>

This is the code-behind:

Protected Sub CustomerSearch_ItemsRequested(sender As Object, e As RadComboBoxItemsRequestedEventArgs)

Dim dal As New Customer

Dim data As DataTable = dal.CustomerSearchName(Session("StoreID"), e.Text).Tables(0)

Dim itemOffset As Integer = e.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + 10, data.Rows.Count)

e.EndOfItems = endOffset = data.Rows.Count

For i As Integer = itemOffset To endOffset - 1

CustomerSearch.Items.Add(New RadComboBoxItem(data.Rows(i)("CustomerName").ToString(), data.Rows(i)("NavPath").ToString()))

Next

e.Message = GetStatusMessage(endOffset, data.Rows.Count)

End Sub

Private Shared Function GetStatusMessage(ByVal offset As Integer, ByVal total As Integer) As String

If total <= 0 Then

Return "No matches"

End If

Return [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offset, total)

End Function

Custom Upload File Fields

Is it possible using RadFileExplorer to customize the upload window with controls to specify additional fields (i.e. description) to be passed to StoreFile(...)? The last parameter of this method is a string array called "arguments", which I assume is for this purpose.

RadTextbox loses focus on AutoPostback in a usercontrol

I have a user control with some RadTextboxes, RadNumericTextboxes, RadComboBoxes. I have this usercontrol on an aspx page which has the RadAjaxManager. I have a requirement to maintain if the controls in the usercontrol have changes, so, I have set the AutoPostBack property to true and on postback, I set ViewState["NameIsDirty"]=true; But my problem is, when the user updates the Name and clicks on tab, the cursor goes to the next control and immediately disappears! Seems like it is getting focussed on the first control on the page. If I dont have the AutoPostBack property set to true, the focus is on the next control and everything is fine. How do I make the focus stay on the control on which it is supposed to be. I searched the forums and tried a few solutions, but they did not work.
I have tried this and it doesnt work:

protected void rdtCCno_TextChanged(object sender, EventArgs e)

{

ViewState["NumberIsDirty"] = true;

string script =string.Format(@"window.setTimeOut(function(){{$find('{0}').Focus();}},10);",rdtCvv2.ClientID);

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "mykey", script,true);

}

protected void rdcExpMonth_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

ViewState["ExpMonthIsDirty"] = true;

var rdAjaxManager = RadAjaxManager.GetCurrent(this.Page);

if (rdAjaxManager != null)

{

rdAjaxManager.FocusControl(rdtAddr1);

}

RadListView databinding with entity framework - insert/update/delete

I am trying to create an ASP.NET page to allow basic CRUD operations using Entity Framework. Using Telerik's RadListView, I have the following HTML:

<telerik:RadListView ID="RadListView1" runat="server" OnNeedDataSource="RadListView1_NeedDataSource">

<ItemTemplate>

<table>

<tr>

<td>First Name:

<%#Eval("FirstName")%>

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnEdit" runat="server" Text="Edit" CommandName="Edit" Width="70px"></asp:Button>

</td>

</tr>

</table>

</ItemTemplate>

<EditItemTemplate>

<table>

<tr>

<td>First Name:

<asp:TextBox ID="txtFirstName" runat="server" Text='<%#Bind("FirstName")%>'></asp:TextBox>

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnUpdate" runat="server" Text="Update" CommandName="Update" Width="70px"></asp:Button>

</td>

</tr>

</table>

</EditItemTemplate>

And here is the code behind:

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

         RadListView1.DataSource = GetData();

}

protected void RadListView1_NeedDataSource(object sender, Telerik.Web.UI.RadListViewNeedDataSourceEventArgs e)

{

RadListView1.DataSource = GetData();

}

private List<Person> GetData()

{

using (BuildingAccessEntities ctx = new BuildingAccessEntities())

{

var query = from a in ctx.People

orderby a.FirstName

select a;

return query.ToList();

}

So far, this code properly displays the populated RadListView. When I click the Edit button, the RadListView switches to Edit mode and allows me to Edit the selected record; however, when I click the Update button to save the record, the changes are not saved.

I have not yet tried to see if inserts and deletes behave this same way.

I'm sure 2-way binding should be something very simple with the RadListView, but I am new to this and have not been able to find many examples to make this work other than by using data source controls (SqlDataSource, EntityDataSource, etc.).

Any assistance will be greatly appreciated!
