Export to pdf with DNN

I've got a radgrid in a dnn module/user control and I want to add exporting to pdf. The module is ajax enable via dnn and I'm pretty sure my problem is related to not doing a full postback. Nothing happens when you click the export to pdf button. I'm trying to register the export to pdf button to postback on the page load with no luck. For some reason I can't find the control.

Any help is appreciated, thanks.

protected void Page_Load(System.Object sender, System.EventArgs e)

{

RadGrid InventoryGrid = (RadGrid)InventoryRadGrid;

Control pdfExportButton = (Control)InventoryRadGrid.MasterTableView.FindControl("ExportToPdfButton");

if (pdfExportButton != null)

ScriptManager.GetCurrent(Page).RegisterPostBackControl(pdfExportButton);

else messageLabel.Text = "Export to PDF Control Not Found";

if (!IsPostBack)

{

}

FindTabByValue

I am new to the company, and new to Telerik controls. In addition, I THINK we are using an older version right now.

What I need to do is have ALL of the following Tabs text values return true from the FindTabByValue if I pass in 'Notes' as the value.

Notes
Notes(0)
Notes(3)

Will this work with this method? Is there a way to do this?

Thanks!

InsertTemplate height

When I place a RadGrid in InsertMode with EditFormType="AutoGenerated", the Insert form template is too tall. When the same grid is in Edit Mode it works fine, the section containing all the controls does not extend the grids overall height.

Any suggestions would be grand.

Thanks,
Reid

RadDataPager Recognizing returns null in some conditions

hi my dear friends :
i have a radcombobox that is in relationship with RadListViw (with RadDataPager Inside)...
when i change the item of rad combobox , so RadListView is Updated... -> selectedIndexxhanged() server-side event...
-------------------------------------------------------------------------------------------------------------------------------------------------------------
my selectedIndexChanged() is like this :

protected void RadcbImagesGroup_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

rlvImages.DataBind();

var raddatapager = (rlvImages).FindControl("RadDataPager1") as RadDataPager;

if (raddatapager != null)

{

raddatapager.FireCommand("Page","First");

}

my radComboBox Item values is like : 1,2,3...

in mode 1 we have 25 pages...
in mode 2 we have 5 pages...
in mode 3 we have 5 pages...

my problem is when we are in mode 1 and put the pageNumber to more than 5 and when i change the combobox Item to mode 2 so



var raddatapager = (rlvImages).FindControl(

"RadDataPager1") as RadDataPager; is null...

but if we put the page# (we are in mode 1) to lower than 5 or equal 5 , and change the radcb item to another everything works fine...

where is the null problem?

thanks for advance

This the server side code for Export Event:

protected void btnExcel_Click(object sender, EventArgs e) //Button Export to Excel Event

{

//Export the data

try

{

isExport = true;

rgQuotes.MasterTableView.ShowHeader = false;

foreach (GridDataItem data in rgQuotes.MasterTableView.GetItems(GridItemType.Item))

{

Label lblStatus = (Label)data.FindControl("lblCredit");

Label lblQuoteApprove = (Label)data.FindControl("lblFinance");

lblStatus.Visible = false;

lblQuoteApprove.Visible = false;

}

rgQuotes.ExportSettings.ExportOnlyData = true;

rgQuotes.ExportSettings.IgnorePaging = true;

rgQuotes.ExportSettings.FileName = "Quotes";

rgQuotes.MasterTableView.ExportToExcel();

}

catch (Exception ex)

{

CommonFunctions.AddErrorLog("Sales=>Quotes", "btnExcel_Click", ex);

}

//Export the data in excel file format

}

Images will be displayed in Excel sheet when application runs in IE Browser
While we switched over to FF then Images wont be exported to Excel sheet.

Reorder columns

I wonder there are some ways to reorder columns in the treelist that declared on design?

My columns are not only Treelistbound columns but also TreeListTemplateColumn and when I add them and load page it's seem fine, but when I do anything (load next page, refresh by button..etc) I show error "ERROR:Invalid column type: "TreeListTemplateColumn"."
Please Try again!

CheckBox within a Radgrid Template Column?

Hi,

I am trying to use a data bound Checkbox in a RadGrid Template Column but have come across several problems.
Firstly, i was trying to use the asp checkbox control. This works for displaying the existing data from my database but i get a DBnull error when i try to insert a new record.
So i tried to resolve this error by trying to capture the DBNull with a CheckNull function:

Public Function CheckNull(ByVal val As Object) As Boolean

If val.GetType Is DBNull.Value.GetType Then

Return False

Else

Return Convert.ToBoolean(val)

End If

End Function

but this didn't work. I then tried a custom CheckBox which overrides the DBNull error but this didn't fix the problem either

Public Class CustomCheckBox

Inherits Web.UI.WebControls.CheckBox

Public Property CheckedOverride() As Object

Get

Return MyBase.Checked

End Get

Set(ByVal value As Object)

If IsDBNull(value) Then

MyBase.Checked = False

ElseIf value.GetType() = GetType(Boolean) Then

MyBase.Checked = value

Else

MyBase.Checked = False

End If

End Set

End Property

End Class

I then searched the Telerik forums for a solution & came across the telerik:GridCheckBoxColumn (from this site http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx) BUT i do not have this available to me! When i enter this control i get an error saying it does not exist.

Is this an old control item which has been phased out or should it still be available to me on the latest version of Telerik controls?

if it isn't available then can you provide an alternative solution for the databound checkbox which is causing a DBnull conversion error?

Regards,

Shuja
