Solution 1

Exposing them via Properties is the normal way:

C#

/// <summary>
/// Gets and sets the value of the input.
/// </summary>
public string Value
    {
    get { return tbValue.Text; }
    set { tbValue.Text = value; }
    }
/// <summary>
/// Gets and set the value of the prompt.
/// </summary>
public string Prompt
    {
    get { return labPrompt.Text; }
    set { labPrompt.Text = value; }
    }

The parent form then just accesses teh properties when it needs the information.

// add row
DataRow rd = this.myTable.NewRow();

//set value
rd[0] = userControl11.Naame;
rd[1] = userControl11.SurName;
rd[2] = userControl11.ParentName;

Member 8983639 16-May-12 5:00am

thanks alot.........:) for the reply and my doubt is like i have to add those usercontrol text values to datagridview on button click which is on main form

OriginalGriff 16-May-12 5:07am

As long as your datagridview isn't databound, you should be able to do it with pretty much the code you have.
What problem are you having with it?

Member 8983639 16-May-12 5:31am

when i click on the button on main form after entering the textbox values name,surname,parentname,qualification theer is an error saying that the loop is running infinite times .................... am a very beginner in .net dnt knw how to use delegates to get the textbox values from child form(usercontrol) texboxes

OriginalGriff 16-May-12 5:37am

What loop?
Why are you using delegates for this at all?
