Clear checkboxes in filter CheckList

[John]

Hi

I have created a method that serverside clears all filters,

foreach (GridColumn column in radGrid.MasterTableView.Columns)
            {
                 
                column.CurrentFilterFunction = GridKnownFunction.NoFilter;
                column.CurrentFilterValue = string.Empty;
            }
            radGrid.MasterTableView.FilterExpression = string.Empty;
            radGrid.MasterTableView.Rebind();

Works as expected,  but the checkboxes in the Checklists are not unchecked.
Can I somehow uncheck the Checklists serverside?
(The grid filertype is "Combined") 

 

Regards
John

Hi John,

There is currently a bug with the clearing of the selected items when CheckList filtering is used. You can take a look at the logged item in our Ideas & Feedback Portal:

• RadGrid - When CheckList filtering is used, clearing columns filter on server-side clears the filter expressions, but does not uncheck the items in the ListBox

Nevertheless, you can refer to the attached sample page, where you will see how you can manually clear the checked values with the CheckList Filtering.

Hope this helps.

Is this fixed yet?

The sample JavaScript didn't work - I tried with both the hard-coded name of the Grid AND with the Client ID version of the Grid and the checkboxes remained clicked.

Interestingly, the JavaScript never fires in the Code Block! 

 

<CommandItemTemplate>
                <div style="padding: 5px 5px;">
                   <div style="float: right;">
                        <asp:LinkButton ID="lbClearFilters" runat="server" CommandName="ClearFilters" OnClick="lbClearFilters_Click" CausesValidation="false" OnClientClick="clearCheckboxes"><img style="border:0px;vertical-align:middle;" alt="" src="/images/filter.gif" /> Clear filters</asp:LinkButton>
                    </div>
                </div>
            </CommandItemTemplate>

 

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

        <script type="text/javascript">

            function clearCheckboxes(sender, args) {

                var clientState = JSON.parse($find("<%# rgRepricingApproval.ClientID %>").get_clientState());

                clientState.checkListFilterValues = [];

                clientState.checkListFilterKeys = [];

                $find("<%# rgRepricingApproval.ClientID %>").set_clientState(JSON.stringify(clientState));

            }

        </script>

    </telerik:RadCodeBlock>

Hi Peter,

Since you are using LinkButton control (and not RadButton as in the attached sample project), the handler of the OnClientClick event should be as shown below:

<asp:LinkButton runat="server" OnClientClick="clearCheckboxes()" ......>....</asp:LinkButton>

You can refer to the following MSDN article for detailed information:

• LinkButton.OnClientClick Property
