Text from TextBox in DataList

Hi,

i have a DataList with a TextBox added by me:

<asp:DataList ID="GradeDataList" runat="server"
DataKeyField="id" DataSourceID="ProjectsObjectDataSource">
<ItemTemplate>
topic:
<asp:Label ID="topicLabel" runat="server" Text='<%#
Eval("topic") %>'></asp:Label><br />
<asp:TextBox ID="GradeTextBox" runat="server"
Text='<%# Grade(Eval("id")) %>' />
</ItemTemplate>
</asp:DataList>

How can I get text from this TextBox?

Thanks in advance,
Etam.Use the .items collection of the datalist to obtain a reference to
your textbox by name.
Once you have the reference, set the value using the textbox's .Text
property.

ie

myDatalist.items("mytexbox").Text="My new value"
First get to the item, then to the textbox:
TextBox myTextBox = myItem.FindControl("GradeTextBox") as TextBox;

But still it is strange... Beacause My GradeDataList has many
GradeTextBoxes. Am I right?
Exactly. This will work for variable of any value type, including enums.

You need first get to the item, something like

TextBox tb = (TextBox)GradeDataList.Items[i].FindControl("GradeTextBox");

Textbox action in datalist

I hope this is as simple as I think it is, but for some reason, I cannot see the forest through the trees. On my page I have a datalist that, during edit mode, displays several text boxes for the user to type in. What I want to is poll a database after the user types in a value into say 'TextBox1'. I just cannot figure out the correct path to the TextBox events when it's a part of the DataList Edit section. Any ideas ? Thanks.It took some digging, but I finally figured out the code to access a textbox within a datalist (thanks to all who helped). I have added the code below and attempted to explain what's going on, but I may not have the wording exactly correct.

Dim i As Integer
Dim crt As Control

Find the datalist control on the page
For i = 0 To Me.DataList.Controls.Count 1
Once the datalist is found, find the textbox control within the datalist
For Each crt In Me.DataList.Controls(i).Controls
Establish a connection to the datalist control line
Dim item As DataListItem = Me.DataList.Controls(i)
Find the text box within the row
Dim tbx As System.Web.UI.WebControls.TextBox =item.FindControl("TextBox1")
If (crt.ID = "TextBox1") Then
If tbx.Text = "Hi" Then
tbx.Text = "Hi There"
Else
tbx.Text = "Bye then"
End If
End If
Next
Next
