Custom validation on textboxes server side RRS feed

  • Question

  • Hi,

    I have asked the question before but I am reposting as i need it on the server side.



    I have a table with about 30 textboxes.
    Each row has 2 textboxes that have the same prefix but different suffix such as txtAvgFrom and  txtAvgTo.
    I need to loop through the table and perform custom validation on the textboxes:
    1- only integers
    2- if both to and from textboxes are filled in I have to check that the value in from textbox is smaller than the from value.
    3- range entered in each textbox is 1-100

    I might need more validations later on. Also, if the to textbox is filled in then the from isn't required and vice versa. No textbox is required.

    I need to do server side validation.
    Should i add customvalidation control? If yes, then for each textbox?
    Do I set controltovalidate?
    I need to display the correct error next to each row when submit button is clicked. And obviously if page is not valid then don't do anything further.

    I am very confused. Appreciate the help.

    The layout is something like this:

        <td> From price </td>
        td><asp:textbox runat=server id=txtPriceFrom></td>
        td>To price</td>
        td><asp:textbox runat=server id=txtPriceTo></td>
        <td> From yield</td>
        td><asp:textbox runat=server id=txtYieldFrom></td>
        td>To yield</td>
        td><asp:textbox runat=server id=txtYieldTo></td>
