Load multiple documents to a radDocument[] array

[Sandhya]

Hi,

I am trying to load documents to a radDocument[] array. When executing below code i  get "exception has been thrown by the target of an invocation c#" error.  Kindly Help.

Here is my code:

RadDocument[] Rd_Ary = new RadDocument[2];
            
Rd_Ary[0]=ImportHtml(Convert.ToString("<P>String1</P>"));
Rd_Ary[1] = ImportHtml(Convert.ToString("<P>String2</P>"));

Alternative code:

 Rd_Ary.SetValue(ImportHtml(Convert.ToString("<P>String1</P>")), 0);
 Rd_Ary.SetValue(ImportHtml(Convert.ToString("<P>String2</P>")), 1);

Hi Sandhya,
 
Thank you for writing.

I have tested this with the following code and there is no exception on my side: 

void button_Click(object sender, EventArgs e)
{
    RadDocument[] Rd_Ary = new RadDocument[2];

    HtmlFormatProvider provider = new HtmlFormatProvider();

    Rd_Ary[0] = provider.Import(Convert.ToString("<P>String1</P>"));
    Rd_Ary[1] = provider.Import(Convert.ToString("<P>String2</P>"));
}

What is the code inside your ImportHtml method? Maybe something is different. 

I am looking forward to your reply.

public RadDocument ImportHtml(string content)
        {
            try
            {

                XamlFormatProvider provider = new XamlFormatProvider();
                return provider.Import(content);
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

Hello Sandhya,

Such input cannot be imported with the XamlFormatProvider. You can use the HtmlFormatProvider instead, or the RichTextEditor to save the  documents first. 

Please let me know if there is something else I can help you with.

Hi,

Thanks for your reply.

I used HtmlFormatProvider and my output was this Telerik.WinForms.Documents.Model.RadDocument

Hello Sandhya,

This is the expected result. Then you can show the document in RadRichTextEditor like this:

void button_Click(object sender, EventArgs e)
{
    RadDocument[] Rd_Ary = new RadDocument[2];

    var provider = new HtmlFormatProvider();
    string s = provider.Export(radRichTextEditor1.Document);

    Rd_Ary[0] = provider.Import(Convert.ToString("<P>String1</P>"));
    Rd_Ary[1] = provider.Import(Convert.ToString("<P>String2</P>"));

    radRichTextEditor1.Document = Rd_Ary[1];
}

Please let me know if there is something else I can help you with.

I have one more doubt.

I want to set header and footer programmatically in a richtextEditor when loading a template.How can i achieve it.

Hello Sandhya,

The following section shows how you can create a header and add it to a document: Headers and Footers.
 
I hope this will be useful.
