Hi,

I would like to dynamically populate the RadDropDownTree client side - but I need all nodes to be fully expanded. The web service databinding scenario would be great, except I can't see any way to make it automatically expand all the nodes. Alternatively I can write a web service to return me a json list of the data I need, but I can't see a way to add nodes to the RadDropDownTree through javascript.

How can I achieve the functionality I want?

Hi,

i try to perform filter operation programmatically. So i created an asp button and attached a server side click event handler. The filter operation should be fired in the event handler:

 protected void Filter_Click(object sender, EventArgs e)
 {
            RadGrid grd = grid;
            grid.MasterTableView.FilterExpression = "([Capture] LIKE 'Kind%')"; // Capture is the id and unique name of a GridBoundColumn
            GridColumn column = grid.MasterTableView.GetColumnSafe("Capture");
            column.CurrentFilterFunction = GridKnownFunction.Contains;
            column.CurrentFilterValue = "Kind";
            grd.EnableLinqExpressions = false;
            GridDataItem item = (grid.MasterTableView.GetItems(GridItemType.Item)[2] as GridDataItem);
            item.FireCommandEvent("Filter", new System.Web.UI.Pair("Kind", "Capture")); // exception is being fired at this line
            grid.Rebind();
}

This code causes an exception:

An exception of type 'System.NullReferenceException' occurred in Telerik.Web.UI.dll but was not handled in user code


   at Telerik.Web.UI.GridColumn.RefreshCurrentFilterValue(GridFilteringItem filteringItem, String functionName)
   at Telerik.Web.UI.GridFilterCommandEventArgs.ExecuteCommand(Object source)
   at Telerik.Web.UI.RadGrid.OnBubbleEvent(Object source, EventArgs e)
   at System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args)

   at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

How can I get it fixed?

Thanks in advance

Hi,

when I try to perform filter operation in a button event handler the FireCommandEvent method causes an exception.

        protected void Filter_Click(object sender, EventArgs e)
        {
            RadGrid grd = grid;
            grid.MasterTableView.FilterExpression = "([Capture] LIKE 'Kind%')";
            GridColumn column = grid.MasterTableView.GetColumnSafe("Capture");
            column.CurrentFilterFunction = GridKnownFunction.Contains;
            column.CurrentFilterValue = "Kind";
            grd.EnableLinqExpressions = false;
            GridDataItem item = (grid.MasterTableView.GetItems(GridItemType.Item)[2] as GridDataItem);
            item.FireCommandEvent("Filter", new System.Web.UI.Pair("Kind", "Capture"));
            grid.Rebind();
        }

Here is the exception:

An exception of type 'System.NullReferenceException' occurred in Telerik.Web.UI.dll but was not handled in user code


   at Telerik.Web.UI.GridColumn.RefreshCurrentFilterValue(GridFilteringItem filteringItem, String functionName)

I am using radgrid, i have used asp link button in GridTemplateColumn .

How to fetch value of label by client side.

Please help. Regards

Greetings,

Looks like a bug was introduced in 2016.2.719+.  Put the following in a blank web form:

<telerik:RadColorPicker ID="RadColorPicker1" ShowIcon="True" runat="server" SelectedColor="Red"></telerik:RadColorPicker> 
<telerik:RadColorPicker ID="RadColorPicker2" ShowIcon="True" runat="server"></telerik:RadColorPicker>

Select a color in one control and it changes in both controls.

Works fine in 2016.2.712 and earlier.

Thanks,

Gary.

Hi telerik team.

I have some questions, i´m working with a user control like this:

<telerik:RadAjaxManagerProxy runat="server">
    <AjaxSettings>
         <telerik:AjaxSetting AjaxControlID="cbTaxesGroup">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="cbTaxes" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

<section>
    <div class="col-md-10">
        <telerik:RadComboBox runat="server" ID="cbTaxesGroup" AllowCustomText="false" EmptyMessage="Selecciona" AutoPostBack="true"               OnSelectedIndexChanged="cbTaxesGroup_SelectedIndexChanged"></telerik:RadComboBox><br />
        <telerik:RadComboBox runat="server" ID="cbTaxes" AllowCustomText="true" MarkFirstMatch="true" AutoPostBack="true" OnSelectedIndexChanged="cbTaxes_SelectedIndexChanged"></telerik:RadComboBox><br />        
    </div>    
</section>

Each cbTaxes depends of cbTaxesGroup selection...

And i´m using this control inside a RadGrid like:

<telerik:GridTemplateColumn UniqueName="templateTaxesColumn" HeaderText="Impuesto">
                            <ItemTemplate>
                                <%# Eval("TaxDescription") %>
                            </ItemTemplate>
                            <EditItemTemplate>
                                <ucCustom:ucTaxesCtrl runat="server" ID="cmbTaxes" />
                                <asp:RequiredFieldValidator runat="server" ControlToValidate="cmbTaxes:cbTaxesGroup" CssClass="validate-control" ErrorMessage=" *" ForeColor="Red"></asp:RequiredFieldValidator>
                                <asp:RequiredFieldValidator runat="server" ControlToValidate="cmbTaxes:cbTaxes" CssClass="validate-control" ErrorMessage=" *" ForeColor="Red"></asp:RequiredFieldValidator>
                            </EditItemTemplate>
                        </telerik:GridTemplateColumn>

But the problem is that the second radcombobox neves is populate...

Someone can help me please?
