Is it possible to rebind the tasks from client side?

Also to close the appointment-tooltip?

Hello

I am working with a line chart and currently I can only set the same type of marker for each data point as the blue line, but I need to set a different type of markers for each data point as the red line. How can I do it?

Dear Support Team and Community,

I have a trouble with the expansion of image properties in the ImageManager.

I would like to add more properties (eg. data-pre, data-post) beside the Telerik's default properties (Alt Text, Long Description, etc...).

Furthermore, I also would like to add the mentioned properties into the panel when I right click on the inserted image in the content of the RadEditor.

Would you help me to solve this problem or send me the relevant references or tutorials.

Thank you so much.

Best regards,

VoVo

Hi,

we have a solution where users can mark locations to architectual drawings simply by clicking the location on the drawing.

Everything works fine with desktop browsers, but not with an Android devices. The problem with Android is that does not get X and Y cordinates.

Click event is fired even with an Adroid but no cordinates.

Please see sample script below:

   <script type="text/javascript">
                var imageEditor;

                function onImageLoad(sender, args) {
                    imageEditor = sender;

                    $telerik.$(imageEditor.get_viewport()).on("click", function (e) {
                        var statusBar = imageEditor._statusBar;
                        var posX = statusBar.get_coorX().innerText;
                        var posY = statusBar.get_coorY().innerText;

         
                    })



                }
        </script>

Greetings!

I'm using the demo of the basic Split Button's functionality as found in  https://demos.telerik.com/aspnet-ajax/button/examples/splitbutton/defaultvb.aspx as the basis of my solutin / question.

I have a need for the right edge of the ContextMenu to be in line with the right edge of the SplitButton. My ContextMenu items are being loaded dynamically depending on certain conditions of the state of the form.

I have tried the following adaptation of the display function:

... but the value "ctxSize.width" keeps being set to 0 , which makes the context menu x position equal to a negative number, and unusable!

Does anyone have any ideas?

Thanks in advance

I've implemented the GanttCustomProvider to give me more properties on the task - using a project supplied by a kind persons at Telerik, think it was Peter Milchev .

However the GetTasks function in the GanttCustomProvider.vb needs to take into account filters specified by a RadComboBox on the calling page however I don't seem to be able to get to that control.

Hi, I'm new to telerik controls. I'm trying to implement auto filter option in the telerik radgrid

   <telerik:RadGrid ID="rgDashboard" ShowStatusBar="true" runat="server" AllowFilteringByColumn="true"
           AutoGenerateColumns="False" AllowSorting="true" OnNeedDataSource="RadGrid1_NeedDataSource"
           onsortcommand="rgDashboard_SortCommand" AllowPaging="true" PageSize="200">
           <GroupingSettings CaseSensitive="false" />
           <PagerStyle Mode="NumericPages" Position="TopAndBottom" ShowPagerText="false"> </PagerStyle>           
           <MasterTableView HeaderStyle-CssClass="goalGridHeader TableHeader" AllowFilteringByColumn="true">
           <Columns>               
                <telerik:GridBoundColumn DataField="Center" HeaderText="Center Name"                 
                 AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"
                            ShowFilterIcon="false" />
                <telerik:GridBoundColumn DataField="Instructor" HeaderText="Instructor Name" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"
                            ShowFilterIcon="false"   />
                <telerik:GridBoundColumn DataField="CenterID" HeaderText="Center ID" AllowFiltering="false"/>
                 <telerik:GridTemplateColumn  HeaderText="" AllowFiltering="false">
                    <ItemTemplate>
                      <asp:LinkButton ID="lnkEdit" Text="View" CssClass="btn btn-view btn-sm" OnClick="lnkEdit_OnClick" runat="server"  />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
            </MasterTableView>
        </telerik:RadGrid>

In code behind, I have filldata which binds the data to radgrid

  private void filldata()
        {
            DataSet ds = new DataSet();
            ds = gdh.GetCentersByFC(UserName, Admin, Email);
            try
            {
                if ((ds != null) && (ds.Tables.Count > 0) && (ds.Tables[0].Rows.Count > 0))
                {
                    lbldispBranch.Text = ds.Tables[0].Rows[0]["Branch"].ToString();
                   // lblLoggedInUser.Text = ds.Tables[0].Rows[0]["FCName"].ToString();
                }

                rgDashboard.DataSource = ds;
                rgDashboard.DataBind();
            }
            catch (Exception ex)
            {
                GeneralHelper.LogFile(ex);
            }
        }

  protected void rgDashboard_SortCommand(object sender, GridSortCommandEventArgs e)
        {
            filldata();
        }

        protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            filldata();
        }

I'm able to get the desired results, but getting below error after filter RadGrid1_NeedDataSource executes

Telerik.Web.UI.GridBindingException: You should not call DataBind in NeedDataSource event handler. DataBind would take place automatically right after NeedDataSource handler finishes execution.
   at Telerik.Web.UI.RadGrid.DataBind()
