unexpected behavior for "select all" client side checkbox

[vlad]

Hi everybody

I have a strange situation when using telerik provided script for persisting client selected rows. This is the code :

function uxRadGrid_RowSelected(sender, arg) {

 

    //add rowKey to selection

    var rowKey = arg.getDataKeyValue("rowKey");

    if (!selected[rowKey]) {

        selected[rowKey] = true;

    }

}

 

function uxRadGrid_RowDeselected(sender, arg) {

 

    //remove rowKey from selection

    var rowKey = arg.getDataKeyValue("rowKey");

    if (selected[rowKey]) {

        selected[rowKey] = null;

    }

 

}

 

function uxRadGrid_RowCreated(sender, arg) {

 

    //select row if in selection

    var rowKey = arg.getDataKeyValue("rowKey");

    if (selected[rowKey]) {

        arg.get_gridDataItem().set_selected(true);

    }

}

 

function uxRadGrid_Created(sender, arg) {
    //nothing here
}

    <telerik:RadGrid ID="uxRadGrid" Skin="Transparent" AutoGenerateColumns="false" ShowHeader="true" Width="100%"

    OnNeedDataSource="uxRadGrid_NeedDataSource" OnItemCreated="uxRadGrid_ItemCreated" OnItemDataBound="uxRadGrid_ItemDataBound"

    PagerStyle-AlwaysVisible="true" PagerStyle-Mode="NumericPages" PagerStyle-Position="Bottom"

    AllowPaging="true" AllowMultiRowSelection="true" AllowSorting="true"

    runat="server">

        <MasterTableView ClientDataKeyNames="rowKey" TableLayout="Auto" GridLines="None">

            <Columns>

                <telerik:GridClientSelectColumn />

                <telerik:GridBoundColumn DataField="rowKey" HeaderText="Row Key" />

                <telerik:GridBoundColumn DataField="user_status" />

                <telerik:GridBoundColumn DataField="user_role" />

                <telerik:GridBoundColumn DataField="user_firstname" />

                <telerik:GridBoundColumn DataField="user_lastname" />

                <telerik:GridBoundColumn DataField="user_email" />

            </Columns>

 

            <SortExpressions>

                <telerik:GridSortExpression FieldName="rowKey" SortOrder="Ascending" />

            </SortExpressions>

        </MasterTableView>

 

        <ClientSettings>

            <ClientEvents OnRowCreated="uxRadGrid_RowCreated" OnRowDeselected="uxRadGrid_RowDeselected" OnRowSelected="uxRadGrid_RowSelected" OnGridCreated="uxRadGrid_Created" />

            <Selecting AllowRowSelect="true" />

        </ClientSettings>

    </telerik:RadGrid>

In my example, I use 3 data rows. The grid is ajaxified.

When I check 2 checkboxes in GridClientSelectColumn, and click on column header to sort items, everything works as expected but "check all" checkbox gets checked (even if only 2 of 3 items are selected) ! When I click on sort again, "check all" gets unchecked.

And when I select all 3 items, and sort, "check all" never gets checked after sorting. Same if I select only one item.

Am I missing something ?

Thanks

Never mind,

I will use a work-around. I just uncheck it every time with jquery in grid created event :

$("[id*='" + guid + "_uxRadGrid']").find(".rgCheck").children(":first").removeAttr("checked");

Hello Vedran,

I can confirm that this is an unexpected behavior and I logged it in our tracking system. Our developers will perform further investigation and try addressing it. Meantime, you can use the workaround, which you are already found.
