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)
   at Telerik.Web.UI.GridFilterCommandEventArgs.ExecuteCommand(Object source)

   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 solved?

Thanks in advance.

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?

I am trying to alter the items collection of a radcombobox which is placed in a radtooltip with JS like

  <telerik:RadToolTip ID="tt_svg_combo" HideEvent="ManualClose" OffsetX="20" RenderMode="Lightweight" Skin="Default" Width="400" Height="400" runat="server">
       <telerik:RadComboBox ID="rcb_tooltip" runat="server"><Items>
            <telerik:RadComboBoxItem Text="aa" Value="aa" />
                                                             </Items></telerik:RadComboBox>
    </telerik:RadToolTip>

and JS:

  var ott
                    ott = $find("<%=tt_svg_combo.ClientID%>");
                    var combo = $find("<%= rcb_tooltip.ClientID%>");
                    var items = combo.get_items();
                    combo.trackChanges();
                    var comboItem

var str='1$2$3$4$5'
                    var a = str.split("$");

                    for (i = 0; i < a.length; i++) {
                        comboItem = new Telerik.Web.UI.RadComboBoxItem();
                        comboItem.set_text(a[i]);
                        comboItem.set_value(a[i]);
                        items.add(comboItem);
                    }

                    combo.commitChanges();
                }
              
                setTimeout(function () {
                    ott.show();
                }, 1000);

None of the added items are showing up on tooltip show.

When I place rcb on the page itself it works OK

"datetime":

case "date":

case "time":

oType =

typeof(DateTime);

break;

case "int":

case "numeric":

oType =

typeof(Int32);

break;

and in ColumnCreated

if

(e.Column is GridDateTimeColumn && e.Column.UniqueName.Contains("Time"))

{

(e.Column

as GridDateTimeColumn).PickerType = GridDateTimeColumnPickerType.TimePicker;

thats all good, but ..

if (e.Column is GridNumericColumn

Hello,

I've been trying to solve the problem by myself for a while now, but in vain.

I have a RadGrid, in which I have a GridClientSelectColumn. I've written JS functions so that selection is saved in a HiddenField even if you navigate through the pages of the grid. The thing is, when I try to export as an Excel file, it doesn't work. I mean that, without adding "IgnorePaging = true", the currently selected rows only are exported. But if I add this property, I would expect that every "selected row" (I mean every row saved in the HiddenField) get exported. Instead, I just get a file with ALL the rows, no matter if they were selected or not. I've been checking the HiddenField content, and it is filled as expected, so I don't know where the problem could come from.

Here is the Excel export function : 

Selected rows are "saved" in the hidden field with JS like this : 

Here is my RadGrid code :
