I know you can export content from a RadEditor to PDF, but can you programatically load a PDF on the server side?

In my scenario, I would like to open a PDF file and get the text-only representation of it.  Loading it into a RadEditor and accessing the text property sounded like a nice idea.  I would also like to do this for other formats, such as Word (Doc/x), and whatever else I can get.

Thanks.

Description: RadEditor's TemplateManager adds a non-existing template into RadEditor.

Problem: The application has a save function that captures RadEditor1's content into an HTML file, "test.html", on the local disk. This file is saved into "~/Templates/test.html". The problem occurs when test.html is edited and reloaded; TemplateManager somehow stores the first copy of test.html and keeps loading it whenever a file named test.html is opened by TemplateManager. test.html can be edited through RadEditor, or Notepad, or even deleted and re-created, but TemplateManager still opens the original copy(which has been deleted and re-created and formatted differently than before).

Code: 
[ASPX]

 

<

 

TemplateManager ViewPaths="~/Templates" />

 

 

[C#]
if

 

 

(e.Argument == "Save")

 

{

 

 

using (StreamWriter saveFile = new StreamWriter(this.MapPath(path), false))

 

{

saveFile.Write(RadEditor1.Content);

}

}


Any help will be greatly appreciated.
Thank you

Is it possible to allow the user to clear the selected date in the calendar?  If the user selects a date, there appears to be no way to clear it.

Thanks

Hi all,

I have designed a rad grid and enable in-place editing mode using this example but when I want to fire server side update command to delete in DB no action fires, and below my code:

 

protected void RadGrid1_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

 

{

 

//Get the GridEditableItem of the RadGrid

 

 

GridEditableItem editedItem = e.Item as GridEditableItem;

 

 

//Get the primary key value using the DataKeyValue.

 

 

string ID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["id"].ToString();

 

 

//Access the textbox from the edit form template and store the values in string variables.

 

 

string name = (editedItem["name"].Controls[0] as CheckBox).Text;

 

 

string insertflag = (editedItem["insertflag"].Controls[0] as CheckBox).Text;

 

 

string updateflag = (editedItem["updateflag"].Controls[0] as CheckBox).Text;

 

 

try

 

{

 

//Open the SqlConnection

 

SqlConnection.Open();

 

//Update Query to update the Datatable

 

 

string updateQuery = "UPDATE Employees set name='" + name + "',insertflag='" + insertflag + "',updateflag='" + updateflag + "' where id='" + ID + "'";

 

SqlCommand.CommandText = updateQuery;

SqlCommand.Connection = SqlConnection;

SqlCommand.ExecuteNonQuery();

 

//Close the SqlConnection

 

SqlConnection.Close();

 

}

 

catch (Exception ex)

 

{

RadGrid1.Controls.Add(

new LiteralControl("Unable to update Employee. Reason: " + ex.Message));

 

e.Canceled =

true;

 

}

Label1.Text =

"Updated";

 

}

I have used label to change text to know whether it get into updatecommand or not, but no changes happens.

Are there any c# additional code to add???
Please advise

Regards

ravi

hi,
We are using Q2 2008 (and don't want to upgrade to Q3 just yet) RAD Menu. The menu gets built dynamically and so we don't know the width of the menu. In Q1 and firefox/ie8 setting no width has been fine - but in ie7 it won't set the width until the event OnMouseOver/Hover has been fired.

Another developer here had the same problem but managed to find the lenght of the longest menu item and times it by 8.5625 and set the width but I can't seem to work that dodgey hack in my code.

Any ideas?

Hi,

When Im using node expand mode of serversidecallback for an ajax'ed node expand, Im finding that a lot of data is posted to the server. The amount of data seems to be additive as well. For example, if I expand one node and it posts back 14k, when I expand the next one which does not return any more data than the first one, it posts back 22k.

I understand that this is due to the viewstate being updated but is there any way to reduce the amount of data being posted.

The viewstate seems to contain each node's imageurl and openimageurl. Is there anyway to set them so that they use one common variable?

our image url's are quite big:
http://localhost/rvservices/WebResource.axd?d=9sITAdMvGK1Qm1ik7fcTRAuCttzSiFEdU7ak4wHdOcaPWw7k0RVlXsufQ613GzmI5kzI5-YeggENTdPMR3JBqxP2md__DsQqWwb_Zectys-6gsnlGHo0FBoxXbLVnO480&t=633722770144766645

Is there a possibility to get the datatable that is set in the radgrid, when i set the datasource..

my problem is that i have a generic list, but i can't save the list in viewstate(no serialization) so i that i can hold my temp data..

okay i can manually fill a datatable with the list-values at first load and save the table in viewstate, but it is so ugly :D and this scenario looks so daily...

thx 4 help
