Retrieving data from Custom Control

[diban]

Hi

I have created a custom user Control (with 5 text boxes) for a job site to accept N Number of Work Experience.

I Load the first Custom control by default on load with a command button to add more Experience. Every time I click the "Add More" button the Custom Control loads on the browser.

My problem is I don't know how to to extract the data from each of the input boxes of each of the control.

Can anyone help me how to do this?

Here are the detail of the files:
Custom Control File: UserControlWorkExperience.asCx
Interface File:UserControlEducation.asPx

Code of UserControlEducation.ASCX

<script runat="server">
		Public Property CompanyName() As String
        Get
            Return txtCompanyName.Text
        End Get
        Set(ByVal Value As String)
            txtCompanyName.Text = Value
        End Set
    	End Property
		Public Property MOJ() As String
        Get
            Return txtMOJ.Text
        End Get
        Set(ByVal Value As String)
            txtMOJ.Text = Value

I see that you've declared the public properties in each of your controls. You should be assigning the values in the input boxes to these public variables. You can then access those values by using something like

MyControl1.MonthOfJoining

Now, if you want to iterate through each of them without knowing in advance how many you have on the page, you should loop through all of the controls in the Page object.

For Each ctl As Control in Page.Controls
If TypeOf ctl Is MyControlType Then
'You can access the info using
CType(ctl,MyControlType).MonthOfJoining
End If
Next
