    How can I set the IE Status bar by CallbackPanel Dynamically?

    Reply Contact

    Hi,

    In my page, I have a button, a textbox, a CallbackPanel, a ASPxGridView, I can input the filter in the textbox  then press the button to get the requited data

    by CallbackPanle using the performCallback method, and show the data in the ASPxGridView.

    I want to implement another feature that display the count of the GridView in the IE Status bar, I implement it using this code as below:

    string statusBarText = "row(s): " + ASPxGridView.Rows.Count;
    ClientScript.RegisterStartupScript(GetType(), "SetStatusBarText", "window.status='"+ statusBarText +"';", true);

    But, I find the page output the same count always, in this case, whatever I change the filter in the textbox, then I press the button to get new data, the count in the

    status bar is never been changed.

     

    I want to know how can I output the latest value in callback method.

     

    Thks!

    Hi Jian,

    Pass the required value (records count) as a part of the callback result
    and process this data within the CallbackComplete client-side event handler.

    Hi, Victor,

    Thank you for you reply quickly.

    I don't know how to return the value as a part of the callback result, I know we can pass the parameter from client to server, please tell me what to do.

    And you mentioned that "Client-side event" is the "EndCallback" event handler?

    Jian, look at the following code:

    ASPX:

    <script type="text/javascript">

        function UpdateWindowStatus() {

            window.status = grid.cpRowCount;

        }

        function OnUpdateButtonClick(s, e) {

            grid.PerformCallback();

        }

        function OnGridViewEndCallback(s, e) {

            UpdateWindowStatus();

        }

    </script>

     

    <dxwgv:ASPxGridView ID="gvGridView" runat="server" AutoGenerateColumns="False" DataSourceID="dsDataSource" KeyFieldName="CategoryID"

        ClientInstanceName="grid" OnCustomJSProperties="OnCustomJSPropertiesAssign">

        <Columns>

            <dxwgv:GridViewDataTextColumn FieldName="CategoryID" ReadOnly="True" VisibleIndex="0">

                <EditFormSettings Visible="False" />

            </dxwgv:GridViewDataTextColumn>

            <dxwgv:GridViewDataTextColumn FieldName="CategoryName" VisibleIndex="1" />

            <dxwgv:GridViewDataTextColumn FieldName="Description" VisibleIndex="2" />

        </Columns>

        <ClientSideEvents EndCallback="OnGridViewEndCallback" />

    </dxwgv:ASPxGridView>

     

    <br />

     

    <table>

        <tr>

            <td>

                Filter by Category Name:

            </td>

            <td>

                <dxe:ASPxTextBox ID="txtFilterBox" runat="server" Width="170px" />

            </td>

            <td>

                <dxe:ASPxButton ID="btnUpdate" runat="server" Text="Update">

                    <ClientSideEvents Click="OnUpdateButtonClick" />

                </dxe:ASPxButton>

            </td>

        </tr>

    </table>

     

    <asp:AccessDataSource ID="dsDataSource" runat="server" DataFile="~/App_Data/nwind.mdb"

        SelectCommand="SELECT * FROM [Categories] WHERE ([CategoryName] LIKE '%' + ? + '%')">

        <SelectParameters>

            <asp:ControlParameter ControlID="txtFilterBox" Name="CategoryName" PropertyName="Text" Type="String" />

        </SelectParameters>

    </asp:AccessDataSource>

    CS:

    protected void Page_Load(object sender, EventArgs e) {

        // TODO: default binding

    }

    protected void OnCustomJSPropertiesAssign(object sender, ASPxGridViewClientJSPropertiesEventArgs e) {

        ASPxGridView grid = (ASPxGridView)sender;

        e.Properties["cpRowCount"] = grid.VisibleRowCount;

    }

     Hasn't support for status bar updates in IE and other browsers pretty much been deprecated by default in recent releases? Possibly off topic, but I had a request related to this type of functionality recently and that is what my research yielded.
