[Solved] ToHtml() in Newer Version's of Grid

[hemant]

Hi ,
  I am getting "Null refrence exception"  when tries to use ToHtml(); It was working perfectly in the previous versions(2010.1.603.1030) but getting this issue when we upgraded to 2010.2.714.1030

Here content = this.ContactListGrid.ToHtml(); gives null refrence exception but content = this.ContactListGrid.ToHtml(this.ContactListGrid.SelectedItems, true);  Works perfectly

i'm using this this.ContactListGrid.ToHtml(); to get all rows from Grid and this.ContactListGrid.ToHtml(this.ContactListGrid.SelectedItems, true);  for only selected records ,....and i can't change that..


We upgraded to new version to get rid of CanUserSelect  issue.

Can you provide DLL which has solution for CanUserSelect  and everything same as 2010.1.603.1030 vesrion ?


Thanks

Hi hemant,

 How about if you try:

grid.Export(stream, new GridViewExportOptions { Format = ExportFormat.Html, Items = grid.Items, ShowColumnHeaders = true });

Ok...
Sorry for incomplete info..
Actuly we dont want the File "Save As" dialogue...if user used Export to Excel option then we just want to Export the records and open it in Excel file. We Take care that each user has excel installed on their machie as we are using

 

ActiveXObject(

"Excel.Application").

It very Urgent and Important requirement by users.....

Thanks
Hemant..

Hello hemant,

 So, you want to get the data from the RadGridView, open Excel and make it open the exported file, without the user having to save the file, then open the file from Excel, etc... Right? Wouldn't it be easier to use copy and paste?

Yes Perfect
It will work like this

Page With Grid will open with Records--> User Right Clicks on Grid and Select option "Export All to Excel" --> All records will be exported to Excel and will open in Excel--> If he/she wants to save then only they can save

Wouldn't it be easier to use copy and paste?
NO :(
Actuly it was like this from many releases and our user dont want to do it using Copy And Paste....

Hi hemant,

 Could you please try to get the HTML string from the RadGridView export via this code:

var options = new GridViewExportOptions
{
    Format = ExportFormat.Html,
    Items = grid.Items,
    ShowColumnHeaders = true
};

var stream = new System.IO.MemoryStream();
grid.Export(stream, options);

var htmlString = new System.IO.StreamReader(stream).ReadToEnd();

Please provide a sample application if this snippet throws an exception.

Hello all,

I got the same Exception even with your code:

NullReferenceException: at Telerik.Windows.Data.TypeExtensions.DefaultValue(Type type)

I using:
RadControls for Silverlight version: 2010.3.1110.1040

Have you a fix for that ?
