        PhtxtCat.Controls.Add(txtCat);// on a placeholder

    }

        lblSubcat = new Label();
        lblSubcat.Text =  "Enter new Sub-Category: ";
        PHsubCat.Controls.Add(lblSubcat);// on a placeholder

        txtSubCat = new TextBox();
        _SubCat = txtSubCat.Text;
        PhtxtSubCat.Controls.Add(txtSubCat);// on a placeholder
    }
}

Here,my problem again is when i click on 'Create Category' link button (lnkCat_Click) dynamically its label and textbox is displayed for category and i have another link button for creating 'SuB-category' and when i click (lnkSubCat_Click) on that button for 'Create Sub category' THE FIRST DYNAMIC CREATED (FOR CATEGORY) LABEL AND TEXTBOX ARE REMOVED.

HERE I WANT TO HOLD THAT DYNAMIC CREATED(CAT AND SUB-CAT) SHOULD BE DISPLAYED TILL I CLICK ON SUBMIT BUTTON ON THE SAME PAGE!

I have two link button to create cat and sub-cat!

CAN U PLEASE HELP ON THIS MATTER? AND IS THIS POSSIBLE?

THANK YOU...EXPECTING A REPLY!
