Forms Data Controls :: GridView TemplateField - How To Access EditItemTemplate Controls

Aug 17, 2010

I have a "simple" gridview that has some columns, and the ability for editing/deleting. I recently found that I can change the editing textbox to a dropdownlist and have follow that, using:

[Code]....

It's quite simple and instead of using an sqldatasource, I have successfully implemented using the sqlclient in the codebehind to bind data only when I want (since this GridView is for "reports" and is queried by many parameters from user inputs).From what I've found online, the only way people have populated the dropdownlist is by using an sqldatasource - is there any way to populate it using the codebehind sqlclient like I have for binding the gridview and other dropdowns on the page that are exactly the same actually. I'd obviously have to set the SelectedValue to be what the value is coming from the database, which I can't see being that difficult.

The tough part seems to be knowing when to access this "MoneyTypeEdit" dropdownlist. I thought it would be in the RowEditing event, so I tried something like:

[Code]....

And I know everything outside of the "inserted code" works, because it was fine before I added that, but the dropdown obviously didn't have any values. And I know the code inside the "inserted code" works because I use it somewhere else on my page to populate a similar dropdown. But I get the error that MoneyTypeEdit is null, and I'm guessing it's because it can't find the "MoneyTypeEdit" dropdownlist.

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:

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)

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

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
