How to add watermark at run time in crystal report using
any of the below procedure
1- Report parameter (simple text) to print on report
2- Report parameter (image path) to get image from path
Any other approach if better to display dynamic watermark?

Crystal supports specifying an image path at runtime.
Right-click your static image on the report layout. Select 'Format Graphic'.
Select the 'Picture' tab.
Note the 'Graphic Location' allows you to enter a formula expression. Enter in that expression the dynamic path to the desired image.

From the textbox shows below i want to get values for textbox object in crystal reports

I would suggest you to save your caption/Header of report within database and fetch from there, it will reduce the complexity.
If you insist on using the form, then pass the changed caption/Header value to the form of crystal report through constructor or global variable approach. create a property within your change caption/header form, set its value and get it within your crystal report form and set it i.e.
((TextObject)reportDocument.ReportDefinition.ReportObjects["Invoice_HeaderText"]).Text="Changed Header";

Generate RDLC Report with two columns

I need to build a report (.RDLC in visual studio 2012) that contais a long text in two columns by page.
I can't just add a new column in the report, because the content above of this long text will be dynamically, so, this control (to fill the text in the second column) must be dynamically too.
Also, i need to add others parts of the report after the text ends.
Somebody knows how to do this?

highlight particular row in Crystal Report based on column value C#.net

how to highlight particular row in Crystal Report based on column value C#.net
After Generate Report I want to Highlight all the Records with Value in the column (Assume "Status") values="OK"
If there is a way to do this using in C#.NET

In your crstal report right click the relevant field object you want to highlight and select the "Format Field.." option. In the border tab tick the "Background" check box and you can enter a condition to select the background color of the field. The script looks something like bellow.
(comment: {user1.username} --> user1 is the table and username is my column.)
if {user1.username}='ok' then

You can use a formula in order to change text properties as shown in here:
Change color of text object using formula in Crystal Reports
Edit:
To highlight you can go to the borders tab and activate the background color checkbox. Then add the formula to add any check you want to do before.
If you want to highlight all the row you can always apply same formula to all fields in the row
