Forms Data Controls :: Pulling The Value Of A TemplateField From A GridView?

Nov 23, 2010

I have a GridView, bound to a table (Meals) in a SqlDataSource.

Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.

When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).

Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.

Here's the code and the error message I'm getting.

ASPX:

[Code]....

And here's the Code Behind:

[Code]....

No design time errors reported but here's the run time error:

Object reference not set to an instance of an object.

On the following line:

Line 28: if (row.RowType == DataControlRowType.DataRow)

Forms Data Controls :: Hiding Gridview By Default?

Sep 21, 2010

I need my gridview to display no records when the user first lands on the page. Right now it's showing all records by default based on a query I've defined in a Table Adapter in my dataset.

I have 2 web controls that the user employs to filter data (or view all records). They are working fine--I just need to have the gridview show nothing by default.

Forms Data Controls :: Get Datakey From Templatefield (dropdownlist) In Gridview

May 21, 2010

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!

TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged

Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub

Forms Data Controls :: GridView BoundField Vs. TemplateField For Updating?

Feb 17, 2011

I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.
