RE: GridView with Password Field
Hi Flyguy,
Regarding on the your scenario that you want to use Password input field
for Gridview editing, I think you can convert the certain column(in
Gridview) to a TemplateField, thus you can customize the "EditTemplate" and
use Password mode TextBox for editing data.
Also, for Password mode textbox, it has a natural limitation that we can
not programmtically assign the value to it(through databinding expression)
like normal mode textbox. One method I used is put an additional Label in
that column which display the original value for the user's reference. Here
is a example page I've used for test:
=========================
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="SqlDataSource1">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="id" HeaderText="id"
ReadOnly="True"
SortExpression="id" />
<asp:TemplateField HeaderText="name" SortExpression="name">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"
Text='<%# Bind("name") %>'
TextMode="Password" ></asp:TextBox>
<br />original value:
<asp:Label ID="lblOld" runat="server" Text='<%#
Eval("name") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#
Bind("name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
=========================
Hope this helps.

RE: GridView with Password Field
Steven,
This is great stuff. My only question is how I get the value that the user
enters into the textbox. I have no idea how I reference the data in my code.

RE: GridView with Password Field
Thanks for your reply Flyguy,
As for the TextBox in template field , if you use "Bind" expression and
datasource control, it automatically provide two-way databinding function.
Are you using custom code to do the database updating(so that you need to
manually get reference to the data in textbox)?
generally, if you use the databound column or standard databinding
expression(two-way) in template, you can register "RowUpdating" event of
gridview and check those fields in the parameter:
=================================
protected void GridView1_RowUpdating(object sender,
GridViewUpdateEventArgs e)
{
//e.Keys;
//e.OldValues;
// e.NewValues;
}
=========================
Please feel free to let me know if you have any other questions.

RE: GridView with Password Field
Thanks for your reply Flyguy,
Yes, if you manually do the update, you need to extract the values(the user
enter for edit/update) and call ADO.NET functions to do the data accessing.
As I mentioned in previous reply, for GridView, the "RowUpdating" is the
proper place where you put your code which extract values from GridView
line and do the updating. For example:
#I assume you use <%# Eval("") %> expression to bind data and the following
is the EditTemplate:
=================
<asp:TemplateField HeaderText="name" SortExpression="name">
<EditItemTemplate>
<asp:TextBox ID="txtPassword" runat="server"
TextMode="Password" ></asp:TextBox>
....................
</EditItemTemplate>
..........................
</asp:TemplateField>
</Columns>
</asp:GridView>
=====================
You can use the below code to extract value from the password textbox:
=========
protected void GridView1_RowUpdating(object sender,
GridViewUpdateEventArgs e)
{
TextBox txtPass =
GridView1.Rows[GridView1.EditIndex].FindControl("txtPassword") as TextBox;
if(txtPass!= null)
Response.Write("<br/>you enter: " + txtPass.Text + " as
password.");
//do your data updating code here
e.Cancel = true;
}
}
==================
it also applies if you have more controls inside the template. Just Find
them via their ID.
Hope this helps.
