Hello,

I'm using programmatic client-side binding with the RadGrid and everything works great.  However, I noticed one interesting thing; when binding no records and setting set_virtualItemCount(0), I'm getting the pager to display 2 records and it says 11 records in 2 pages... why would this be?

I do not have custom paging enabled.

Thanks.

I have a radgrid created as below:
//--------------------------------------------------------ASPX---------------------------------------
 <telerik:RadGrid id="deadmitStudents" runat="server" AllowFilteringByColumn="true" Width="100%"  
     AutoGenerateColumns="false" PageSize="30" AllowPaging="true" OnNeedDataSource="OnNeedDataSource_AdmittedStudents">
    <MasterTableView DataKeyNames="IndexNumber" CommandItemDisplay="Top" TableLayout="Auto" AllowFilteringByColumn="True" FilterItemStyle-Wrap="true" FilterItemStyle-Width="40px">
                        <Columns>
                        <telerik:GridTemplateColumn AllowFiltering="True"  Resizable="true" UniqueName="IndexNumber" HeaderText="Index Number">
                                <ItemTemplate>
                                <asp:Label ID="indexNumberLabel" runat="server" Text='<% #Bind("IndexNumber") %>' ForeColor="Black" Font-Size="Medium"></asp:Label>
                                </ItemTemplate>
                                 </telerik:GridTemplateColumn>
                            <telerik:GridTemplateColumn AllowFiltering="True" Resizable="true" UniqueName="FullName" HeaderText="Full Name">
                                <ItemTemplate>
                                <asp:Label ID="fullnameLabel" runat="server" ForeColor="Black" Font-Size="Medium" Text='<% #Bind("FullName") %>'></asp:Label>
                                </ItemTemplate>
                                 </telerik:GridTemplateColumn>
                       <telerik:GridTemplateColumn AllowFiltering="False"  UniqueName="deAdmit" HeaderText="DeAdmit">
                            <ItemTemplate>
                            <asp:CheckBox ID="chkDeadmit" runat="server" />
                                </ItemTemplate>
                                 </telerik:GridTemplateColumn>
                    </Columns>
                     </MasterTableView>
    </telerik:RadGrid>
All I want is to have a simple Filtering on some columns as created in the RadGrid. When executed, i get the following error message

is neither a DataColumn nor a DataRelation for table .

Please kindly help.
Check my code behind below:
//--------------------------------------------------------CODE BEHIND---------------------------------------
    protected void OnNeedDataSource_AdmittedStudents(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            try
            {
                deadmitStudents.DataSource = getAdmittedStudents(RadComboBoxCampus.SelectedValue, int.Parse(RadComboBoxIntake.SelectedValue),
                    RadComboBoxAcademicYear.SelectedValue, int.Parse(RadComboBoxStudyTime.SelectedValue));
            }
            catch
            {
            }
        }
          protected DataTable getAdmittedStudents(string campus,int intake, string academicYear, int studyTime)
        {
            SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["Main.ConnectionString"]);
            string query = "select StudentId,IndexNumber,(coalesce(SurName,'') + ' ' + coalesce(OtherNames,'')) as fullname, ProgrammeName as Programme,Intake,EnrollmentType, " +
           "AcademicYr,Campus from GeneralStudentInfo where Intake='" + intake + "'" +
           "and AcademicYr='" + academicYear + "' and Campus='" + campus + "' and EnrollmentType='" + studyTime + "'";
            //SqlConnection conn = new SqlConnection(ConnString);

            conn.Open();
            SqlCommand cmd = new SqlCommand(query,conn);
            SqlDataAdapter adapter = new SqlDataAdapter(cmd);
            DataTable myDataTable = new DataTable();
            try
            {
                adapter.Fill(myDataTable);
            }
            finally
            {
                conn.Close();
            }
            return myDataTable;

        }
       

Hi.

I have a RadUpload control in my page. I have set the AllowedMimeTypes to images only.


I want to make sures the image being uploaded is of a specific dimension, let's say 300x100 pixels. I can check this on server side before uploading the file. But is there any way I can check it on client side after the user selects the file? If the image is not of the specified size then it should popus up an alert saying image is not of the appropriate dimension and the ruImage controls is blank again.

Thanks.

Hi,
 I need to invoke

OnItemCommand

 event on a click of a Image button under  <telerik:GridTemplateColumn>

I am able to do so on Linkbutton but not with Image button.

My code is this.

<

telerik:GridTemplateColumn UniqueName="TemplateColumnDelete" Groupable="False">

<HeaderStyle Width="45px"></HeaderStyle>

<ItemTemplate>

<asp:LinkButton ID="lnkButtonDelete" runat="server" CommandName="Delete" Text="delete"></asp:LinkButton>

<!-- <asp:ImageButton ID="imgButtonDel" ImageUrl="~/Images/bt_delete.gif" runat="server"

CommandName="Delete"></asp:ImageButton>-->

</ItemTemplate>

</telerik:GridTemplateColumn>

Hello,

I would like some buttons on my page to have the same style as the buttons I view on the radConfirm window when using the Web20 skin.  Can somebody point me to the style used for those buttons?

Thanks.

I have some problems with adding items to RadComboBox on the client-side. I used the sample code from your site and it works great when executed via button click. But when I execute JavaScript function via ScriptManager.RegisterJavaScript it does not work. Problem is that $find returns null. 

Here is the contents of my .aspx file:
 

 

And my .cs file

I have implemented a confirm close window for closing a RadWindow which works fine, however I want to only show the dialog if the user clicks Cancel. I have the following code:

Calling Window:
Closing window:
I am getting the error Object doesn't support this property or method.

I can confirm that the text (btndesc) is "Cancel" when the function is fired, but the argument is not being received on the calling window. Any help is appreciated.

I thought I'd share some javascript code that will automatically deselect a click on a link that has target="_blank" since it is a popup window.  Put in OnClientItemClicked="RadPanelBarClicked" your RadPanelBar declaration.

function RadPanelBarClicked(sender, eventArgs) {

 

 

// Dont' select links with target.

 

 

 

var item = eventArgs.get_item();

 

 

var target = item.get_target();

 

 

if (target)

 

{

item.set_selected(

false);

 

}

}

Hello All,

i honestly tried to find if this have been asked before but to no avail.

i have a user control that is bind-able to inside a GridTemplateColumn of a datagrid, it works fine and it displays the data, the problem is when the grid is sorted for example, all the data is lost.

i think i can solve this using a hidden control inside the usercontrol, but i am not sure yet, and i would like to know if there is something i am missing


to reproduce:
