This sounds like you want to do a count on the number of rows returned to your datagrid. Do a datagrid.Items. Count on your datagrid. This should give you the number of rows returned. Save this value in a session variable. Then in the page load of your worker page assign the value of the textbox to the value of the session variable.

Make sure that in the page load of your worker page you check to see if the session variable is null before assigning the value to the textbox. If it is null then you will know that datagrid has not returned any results yet.

The best way would be to declare a public property in your child form, which you can then access from the calling parent form.

in C# it would look something like this:-

child form:

private System.Data.DataSet searchResults = new System.Data.DataSet();
 
public System.Data.DataSet SearchResults
{
    get { return searchResults; }
    set { searchResults = value; }
}
 
protected void btnSearch_Click(object sender, EventArgs e)
{
    //Do your search code, populating the searchResults DataSet
    .
    .
    searchResults = <Your search results object>;
    this.Hide();
}
 

Then in the parent form:

protected void btnSearch_Click(object sender, EventArgs e)
{
    frmSearchChild frm = new frmSearchChild();
    frm.ShowDialog();
    txtNumberOfRows.Text = frm.SearchResults.Tables[0].Rows.Count.ToString();
    frm.Close();
}
 

Hope it helps!

That I can't do - I have no idea how you're search works!!!! Remember that I used a DataSet as an example, you can make your searchResults property return any object type...
