I have a grid and a telerik button.  When I click the button I want a Save As prompt dialog to appear so the user can change the file name and save the file locally to whichever destination they choose.  But when I click on my button nothing happens?  I am testing this through localhost\ does this function not work unless its run from the actual server? Or should it behave the same even when running from localhost? Here is a copy of my grid.

                                                  <telerik:RadAjaxPanel ID="pnlUpload" runat="server" height="580px" width="980px" LoadingPanelID="lpnUpload">  

  <telerik:RadButton ID="cmdExportPayrolFile" runat="server" Enabled="False" Skin="Metro" Text="Export Payroll File">
                                                    </telerik:RadButton>

<telerik:RadGrid ID="dgExportReport" runat="server" AllowPaging="True" AutoGenerateColumns="False" CellSpacing="0" GridLines="None" Skin="Sitefinity" Width="100%">
                                            <ExportSettings>
                                                <Csv ColumnDelimiter="Comma"
                                                     RowDelimiter="NewLine"
                                                     EncloseDataWithQuotes="False"
                                                     FileExtension ="txt"
                                                 />
                                            </ExportSettings>
                                            <MasterTableView PageSize="15">
                                                <Columns>
                                                    <telerik:GridBoundColumn DataField="EmplID" FilterControlAltText="" HeaderText="Emp Id" UniqueName="dgEmplID">
                                                    </telerik:GridBoundColumn>
                                                    <telerik:GridBoundColumn DataField="FullName" FilterControlAltText="" HeaderText="Employee" UniqueName="dgLastName">
                                                    </telerik:GridBoundColumn>
                                                    <telerik:GridBoundColumn DataField="CostCenterID" FilterControlAltText="" HeaderText="Cost Center" UniqueName="dgCostCenter">
                                                        <ItemStyle HorizontalAlign="Right" />
                                                    </telerik:GridBoundColumn>
                                                    <telerik:GridBoundColumn DataField="Total" DataFormatString="{0:$###,##0.00}" FilterControlAltText="" HeaderText="Total" UniqueName="dgTotal">
                                                        <ItemStyle HorizontalAlign="Right" />
                                                    </telerik:GridBoundColumn>
                                                </Columns>
                                                <PagerStyle PageSizeControlType="RadComboBox" />
                                            </MasterTableView>
                                            <PagerStyle PageSizeControlType="RadComboBox" />
                                            <FilterMenu EnableImageSprites="False">
                                            </FilterMenu>
                                        </telerik:RadGrid>
        </telerik:RadAjaxPanel>

========================
VB CODE BEHIND
=========================

    Protected Sub cmdExportPayrolFile_Click(sender As Object, e As EventArgs) Handles cmdExportPayrolFile.Click

        dgExportReport.MasterTableView.ExportToCSV()

    End Sub


Am I missing something in the grid properties? Does this feature only work if the page is run from the server and NOT localhost? I am populating the grid using advanced binding upon a combo box select index changed.

Thanks

Hi Stefan,

Please add the below code snippet to your code to Export to CSV on button click.

ASPX:
<telerik:RadAjaxPanel ID="pnlUpload" runat="server" ClientEvents-OnRequestStart="onRequestStart">
    <telerik:RadButton ID="cmdExportPayrolFile" runat="server" Skin="Metro" Text="Export Payroll File"       OnClick="cmdExportPayrolFile_Click">
    </telerik:RadButton>
    <telerik:RadGrid ID="dgExportReport" runat="server" >
    . . . . .
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

JS:
<script type="text/javascript">
    function onRequestStart(sender, args) {
        if (args.get_eventTarget().indexOf("cmdExportPayrolFile") >= 0)  // ID of Button to Set Ajax false on the Button Click
            args.set_enableAjax(false);
    }   
</script>

Thanks,
Princy

Hey Princy,

Thanks for this.  But I have paging enabled so I am only getting the first page of the grid.  I need all of the data.  Plus this just loads the text into a browser window.  I need a "Save As" box to appear so the client can save the file locally.  Also I would like to be able to turn certain fields off during the export as I only need some of the fields (EmplID, CostCenterID and Total)  not all of them.

<telerik:RadGrid ID="dgExportReport" runat="server" AllowPaging="True" AutoGenerateColumns="False" CellSpacing="0" GridLines="None" Skin="Sitefinity" Width="100%">
    <ExportSettings
        FileName ="DoesThisWork.txt"
        Csv-ColumnDelimiter ="comma"
        Csv-RowDelimiter="NewLine"
        Csv-EncloseDataWithQuotes="False"
        Csv-FileExtension ="txt">
    </ExportSettings>
    <MasterTableView PageSize="15">
        <Columns>
            <telerik:GridBoundColumn DataField="EmplID" FilterControlAltText="" HeaderText="Emp Id" UniqueName="dgEmplID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="FullName" FilterControlAltText="" HeaderText="Employee" UniqueName="dgLastName">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="CostCenterID" FilterControlAltText="" HeaderText="Cost Center" UniqueName="dgCostCenter">
                <ItemStyle HorizontalAlign="Right" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Total" DataFormatString="{0:$###,##0.00}" FilterControlAltText="" HeaderText="Total" UniqueName="dgTotal">
                <ItemStyle HorizontalAlign="Right" />
            </telerik:GridBoundColumn>
        </Columns>
        <PagerStyle PageSizeControlType="RadComboBox" />
    </MasterTableView>
    <PagerStyle PageSizeControlType="RadComboBox" />
    <FilterMenu EnableImageSprites="False">
    </FilterMenu>
</telerik:RadGrid>

Hi Stefan,

In order to export the entire data,please set IgnorePaging property of the ExportSettings to true.To hide a column on export you can set it's visibility to false.Please try the following code snippet,which shows confirm box to export.

ASPX:
<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
</telerik:RadWindowManager>
<telerik:RadAjaxPanel ID="pnlUpload" runat="server" ClientEvents-OnRequestStart="onRequestStart">
    <telerik:RadButton ID="cmdExportPayrolFile" runat="server" Skin="Metro" Text="Export Payroll File"
        OnClick="cmdExportPayrolFile_Click" OnClientClicking="OnClientClicking">
    </telerik:RadButton>
    <telerik:RadGrid ID="dgExportReport" runat="server" >
       . . . .
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

C#:
protected void cmdExportPayrolFile_Click(object sender, EventArgs e)
   {   
       dgExportReport.MasterTableView.GetColumn("CoulmnUniqueName").Visible = false; // To hide a column on export
       dgExportReport.ExportSettings.IgnorePaging = true; //To export all the pages
       dgExportReport.MasterTableView.ExportToCSV();
   }

JS:
<script type="text/javascript">
function onRequestStart(sender, args) {
 if (args.get_eventTarget().indexOf("cmdExportPayrolFile") >= 0)  // ID of Button to Set Ajax false on the Button Click
            args.set_enableAjax(false);
}
function OnClientClicking(sender, args) {
    var callBackFunction = Function.createDelegate(sender, function (argument) {
        if (argument) {
            this.click();
        }
    });
    var text = "Are you sure you want to Export the Grid?";
    radconfirm(text, callBackFunction, 300, 100, null, "Title");
    args.set_cancel(true);
}   
</script>

Thanks,
Princy

Hey Princy,

Thanks again.  This helps.  Only issue I have now is I set Export Only Data = true but I am still getting the column headers on the first row?

<ExportSettings
    FileName ="yea_ok"
    IgnorePaging =" True"
    ExportOnlyData=" True"
    Csv-ColumnDelimiter ="comma"
    Csv-RowDelimiter="NewLine"
    Csv-EncloseDataWithQuotes="False"
    Csv-FileExtension ="txt"
    OpenInNewWindow=" True">
    <Csv EncloseDataWithQuotes="False" />
</ExportSettings>


With dgExportReport
    .ExportSettings.FileName = "ippPayRoll_" & cboReportPeriod.Text & "_" & cboReportYear.Text
    .ExportSettings.ExportOnlyData = True
    .MasterTableView.GetColumn("dgEmplID").Visible = True
    .MasterTableView.GetColumn("dgTotal").Visible = False
    .MasterTableView.ExportToCSV()
End With

Hi Stefan,

I have tried your code and it works fine at my end.Please try, From Q2 2013 a new property named Exportable has been introduced. This property allows you to choose whether a certain column should be included in the exported file or not. By setting this property to false the related column will be excluded from the exported file. Its default value is true.

ASPX:
<telerik:GridBoundColumn Exportable="false" DataField="Name" HeaderText="Name" UniqueName="Name"  />

OR can you try setting the following code to hide a column.

VB:
_with1.MasterTableView.Columns.FindByUniqueName("ShipCity").Visible = False

Thanks,
Princy

Hi Stefan,

Please try the following code snippet to hide the headers when exporting.

VB:
Protected Sub cmdExportPayrolFile_Click(sender As Object, e As EventArgs)
    Dim _with1 = dgExportReport
    _with1.ShowHeader = False
    _with1.Rebind()
    _with1.MasterTableView.ExportToCSV()
End Sub

Thanks,
Princy
