Hello,

 

I just came across an issue trying to enable/disable the Treeview control

It is declared this way : 

<telerik:RadTreeView RenderMode="Classic" runat="Server" ID="trProvince" Height="350" CheckBoxes="True" TriStateCheckBoxes="true"  CheckChildNodes="true" OnClientNodeClicked="ClientNodeClicked" Enabled="False" CssClass="Province"  >

 

Next of it, there's a checkbox that allows to enable/disable it

 

Here's the JS doing that : 

function ToggleRow(sender, eventArgs) {
    var rowClass = "." + sender.get_id().substring(3);
    var isChecked = sender.get_checked();
 
    console.log(rowClass);
    console.log(isChecked);
 
    $(rowClass).each(function() {
        $(this).each(function () {
            var element = $find($(this)[0].id);
 
            console.log(element);
            console.log("enabled :" + element.get_enabled());
 
            if (isChecked) {
                element.enable && element.enable();
                element.set_enabled && element.set_enabled(true);
            } else {
                element.disable && element.disable();
                element.set_enabled && element.set_enabled(false);
            }
                                 
        });
    });
}

 

It's working as in : When checkbox is checked, I can click the checkboxes in the TreeView, expand/collapse its node but it still has a "disabled" style (greyed)

How do I get it to remove the grey layer on the control?

Thank you 

Telerik version : 2017.1.118

Within a step of my radwizard I need a button that is supposed to dynamically add some fields to my form as needed. No matter what I do, the button click event won't fire. What am I missing? I've added a simple demo to demonstrate:

<telerik:RadWizard RenderMode="Lightweight" ID="RadWizardIncidentGroupA" runat="server" CssClass="formfont" Width="100%" OnClientLoad="OnClientLoad" Skin="Bootstrap"
OnClientButtonClicking="OnClientButtonClicking"
OnFinishButtonClick="RadWizardIncidentGroupA_FinishButtonClick" 
 OnCancelButtonClick="RadWizardIncidentGroupA_CancelButtonClick"
BorderColor="#cccccc">
<WizardSteps>
     <telerik:RadWizardStep ID="RadWizardStep1" Title="Administrative" StepType="Start" DisplayCancelButton="true" 
                 runat="server">
                    <div class="inputWrapper">
                         <asp:Label ID="lblTest" Text="Test1" runat="server"></asp:Label>
                         <asp:Button ID="ChangeText" runat="server" Text="Add an Offense" OnClick="ChangeText_Click" />
                    </div>
               </telerik:RadWizardStep>

         </WizardSteps>

</telerik:RadWizard>

 

CODEBEHIND:

protected void ChangeText_Click(object sender, EventArgs e)
{
            lblTest.Text = "Test2";
}

Hi, I have a page that contains a RadComboBox that let's the user select a group name and a RadGrid that displays the members of the selected group.  I have added a setting to the RadAjaxManager to make the combo box update the grid.  That part seems to be working as the loading panel is shown over the grid each time I pick a different value from the combo box.  The problem is that the data in the grid doesn't change, unless I click the refresh button on the grid.

 

I set a breakpoint in my NeedDataSource event handler and I can see that the AJAX request occurs, but the handler is not invoked.  Is this the expected behavior?  If so, what is the correct way to achieve my desired outcome?

 

<telerik:RadAjaxManager ID="RadAjaxManager" runat="server">
   <AjaxSettings>
     <telerik:AjaxSetting AjaxControlID="RadComboBoxCustomGroups2">
       <UpdatedControls>
         <telerik:AjaxUpdatedControl ControlID="RadGridGroupMembers" LoadingPanelID="RadAjaxLoadingPanel" />
       </UpdatedControls>
     </telerik:AjaxSetting>
  </AjaxSettings>
</telerik:RadAjaxManager>

 

<asp:Panel ID="CustomizeCustomGroupPanel" runat="server" GroupingText="Customize Custom Group" Width="635px">
  <div>
    <div class="InlineTable">
      <telerik:RadComboBox ID="RadComboBoxCustomGroups2" runat="server"

                           DataValueField="Group_Id" CssClass="radcombobox" AutoPostBack="True" />
    </div>
  </div>
  <br />
  <div>

                       OnUpdateCommand="RadGridGroupMembers_UpdateCommand" OnInsertCommand="RadGridGroupMembers_InsertCommand">
        <MasterTableView CommandItemDisplay="Top" EditMode="InPlace" DataKeyNames="Branch_Id">
          <Columns>
            <telerik:GridEditCommandColumn />
            <telerik:GridBoundColumn DataField="Branch_Id" HeaderText="Branch ID" UniqueName="Branch_Id" ReadOnly="true" Display="false">
            </telerik:GridBoundColumn>

I have a grid with a ClientSelectedItem column and an item template column with a list in it. When the page loads the ClientSelectedItem is disabled. I want to enable it client side when a value is selected in the dropdown, or change it back to disabled if they change the selection in the dropdown back to nothing. Here's the column section of the grid.

<Columns>
    <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderStyle-Width="47px" />
    <telerik:GridBoundColumn DataField="CaseId" UniqueName="CASEID" Visible="false" />

                CommandName="Popup" />
        </ItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridBoundColumn UniqueName="SSN" HeaderText="SSN" DataField="SSN" ShowFilterIcon="false"

            <telerik:RadDropDownList ID="ddlSelectedSqdLdr" runat="server" Width="100" OnClientItemSelected="modifySelection" DefaultMessage="Select...">

Hello,

I know there is an example how to show and hide the loading panel over one single page-element at the documentation. But I wonder if it is possible to show and hide the loading panel over multiple elements of the page, e.g. over a toolbar at the top and a grid at the bottom of the page.

Thanks in advance.

Kind regards

Felix

Hello,

I saw many posts with issues on filters, but none of them looks similar to my issue.
The classic filter works perfectly but the Checklist filter doesn't. If I try Combined, the classic functionnality works and the checklist doesn't.
Please note that I tried to change the binding way for my grid (using the NeedDataSource event), but it doesn't change anything. The classic filter is still working while the checklist filter still doesn't.

Here is some part (that I think pertinent) of my code. I generate everything from code behind in the Page_Load method:

var grid = new RadGrid();
grid.DataSourceID = myDataSource;
grid.AllowPaging = false;
grid.ColumnCreated += Grid_ColumnCreated;
grid.AutoGenerateColumns = true;
grid.AllowFilteringByColumn = true;
grid.FilterType = GridFilterType.Combined;
grid.FilterCheckListItemsRequested += Grid_FilterCheckListItemsRequested;
grid.ClientSettings.Scrolling.AllowScroll = true;
grid.ClientSettings.Scrolling.UseStaticHeaders = true;
grid.MasterTableView.TableLayout = GridTableLayout.Auto;

grid.ItemCommand += Grid_ItemCommand;

protected void Grid_ColumnCreated(object sender, Telerik.Web.UI.GridColumnCreatedEventArgs e)
{
    RadGrid grid = sender as RadGrid;
    if (e.Column is GridBoundColumn)
    {
        GridBoundColumn column = (GridBoundColumn) e.Column;
        column.AutoPostBackOnFilter = true;
        column.FilterCheckListEnableLoadOnDemand = true;
        column.CurrentFilterFunction = GridKnownFunction.Contains;
    }
}
private void Grid_FilterCheckListItemsRequested(object sender, GridFilterCheckListItemsRequestedEventArgs e)
        {
            string dataField = (e.Column as IGridDataColumn).GetActiveDataField();
 
            var grid = sender as RadGrid;
            var ds = grid.DataSourceObject as SqlDataSource;
            Regex reg = new Regex("FROM(.+)ORDER");
            string request = "SELECT DISTINCT t." + dataField + " " + reg.Match(ds.SelectCommand).Value + " BY t." + dataField + " ASC";
 
            e.ListBox.DataSource = GetFilterTable(request);
            e.ListBox.DataKeyField = dataField;
            e.ListBox.DataTextField = dataField;
            e.ListBox.DataValueField = dataField;
            e.ListBox.DataBind();
        }

 

The FilterCheckListItemsRequested is working and I have, for each columns, 1 checkbox for each different values inside. Notice however how I had to make a Regex on the SelectCommand as I don't know which grid I'm in inside this event. (If someone has a better way ?).

Anyway, regarding the checklist filter, when I check a checkbox and click on "Apply", a postback is done and the Grid_ItemCommand event is raised. However it looks like the "filter value" is empty.

private void Grid_ItemCommand(object sender, GridCommandEventArgs e)
{
    if(e.CommandName == RadGrid.FilterCommandName)
    {
        GridFilteringItem filter = (GridFilteringItem) e.Item;
        string value = ((filter[currentCol].Controls[0]) as TextBox).Text;
         
        Pair command = (Pair) e.CommandArgument;
 
        /* IF CLASSIC FUNCTIONNALITY IS USED
        *   command.First = "Contains"
        *   command.Second = myColumnName
        *   value = theFilterStringIInputed
        */
         
        /* IF CHECKLIST FUNCTIONNALITY IS USED
        *   command.First = "5"
        *   command.Second = myColumnName
        *   value = Empty
        */
    }
}

 

Does someone know how to get the values of the selected checkbox ?

Or what did I do wrong here ?

Thank you.
Regards,
Guilhem

I'm creating a grid programatically based on the "table" a user selects from a dropdown box. I don't have the grid defined in the aspx, just a placehold for it. I want the user to be able to add a row (using the add record button) and update values (using the "edit" column). I can't find how to "wire up" getting the RadGrid1_InsertCommand and RadGrid1_UpdateCommand to be called. AllowAutomaticUpdates and AllowAutomaticInserts are false. IF I had defined the grid in the aspx page I would have included 'OnInsertCommand' and 'OnUpdateCommand', but I can't understand how to do that since I'm doing everything in the code behind. What am I missing? Any help is greatly appreciated.

Hi Telerik Team,

I have encountered a problem while using rad combobox in asp wizard where my combobox could not function, i'm using the 2016 telerik dll.

It can only function when using rendermode= native, is there any other solution beside using rendermode = native?

Before this i'm using older version of telerik dll which does not cause this problem, can you please share with us the solution regarding this?

Your response are highly appreciated.
