Range Validator

The RangeValidator does exactly what the name implies; it makes sure that the user input is within a specified range. You can use it to validate both numbers, strings and dates, which can make it useful in a bunch of cases. Since we validated numbers the last time, we will try with a date this time.

ex:Date:








The date format might seem a bit weird to you if you're not from Europe, where we use dd-mm-yy. You can just change it if it doesn't fit the date format on the machine you're working on. Now, try running the website, and enter a date in our new TextBox. It's only valid if the date is within 2006, and a cool sideeffect is that the date is also checked for validity.

GridView1_SelectedIndexChanged

I have a gridview which is being populated with no problems.

I want to be able to reference the data from the cells in the row but
having followed an example on MSDN cannot get any data to be displayed
in a text box
no matter which cell index I provide.

I tried a row of code that successfully displays the rowindex of the
selected row.

The code with comments is below:

protected void GridView1_SelectedIndexChanged(object sender,
EventArgs e)
{
// Get the currently selected row using the SelectedRow
property.
GridViewRow row = GridView1.SelectedRow;

//This row doesn't put anything in the text box (code copied
from MSDN)
TextBox2.Text = row.Cells[2].Text;

//This row (when not commented out and line above commented
out) puts the row index in the text box
//TextBox2.Text = GridView1.SelectedRow.RowIndex.ToString();
}
