Hi.
I am wondering how I can get the value from an asp.net textbox that is dynamically created inside an asp:datalist.
I would like to then insert these values back into the database.

For example I would like to get the value from Question 2 and then parse the value to my database insert method.
How can this be done as the text boxes are generate dynamically in the data list?
I have written the following

I have written the following
<asp:DataList runat="server" id="dgQuestionnaire" DataKeyField="QuestionID" CssClass="confirm">
<ItemTemplate>
<h3>Question <asp:Label ID="lblOrder" runat="server" Text='<%# Container.ItemIndex + 1 %>'></asp:Label></h3>
<asp:TextBox runat="server" ID="QuestionName" Text='<%# Eval("QuestionText") %>' CssClass="form"></asp:TextBox>
<asp:DataList ID="nestedDataList" runat="server">
<ItemTemplate>
<asp:TextBox ID="AnswerBox" runat="server" CssClass="form" Text='<%# Eval("AnswerTitle") %>' Width="300px"></asp:TextBox>
</ItemTemplate>
</asp:DataList>
<asp:Button runat="server" ID="updateName" CssClass="button_update" style="border: 0px;" onClick="UpdateQuestionName_Click" />
</ItemTemplate>
</asp:DataList>
Here is the code behind
protected void UpdateQuestionName_Click(object sender, EventArgs e)
{
int QuestionnaireId = (int)Session["qID"];
GetData = new OsqarSQL();
// Update question name
GetData.InsertQuestions(QuestionName.Text, QuestionnaireId);
} // End NewQNRButton_Click
public void BindParentDataList(int QuestionnaireID)
{
_productConn = new SqlConnection();
_productConnectionString += "data source=mssql.myurl.com; Initial Catalog=database_2;User ID=userid;Password=aba123";
_productConn.ConnectionString = _productConnectionString;
SqlCommand myCommand = new SqlCommand("GetQuestion", _productConn);
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.Parameters.Add(new SqlParameter("@QUEST_ID", SqlDbType.Int));
myCommand.Parameters[0].Value = QuestionnaireID;
// check the connection state and open it accordingly.
_productConn.Open();
// Sql datareader object to read the stream of rows from SQL Server Database
SqlDataReader myDataReader = myCommand.ExecuteReader();
// Pass the Sql DataReader object to the DataSource property
// of DataList control to render the list of items.
dgQuestionnaire.DataSource = myDataReader;
dgQuestionnaire.DataBind();
// close the Sql DataReader object
myDataReader.Close();
// check the connection state and close it accordingly.
if (_productConn.State == ConnectionState.Open)
_productConn.Close();
// foreach loop over each item of DataList control
foreach (DataListItem Item in dgQuestionnaire.Items)
{
BindNestedDataList(Item.ItemIndex);
}
}
public void BindNestedDataList(int ItemIndex)
{
int QuestionID = Convert.ToInt32(dgQuestionnaire.DataKeys[ItemIndex]);
SqlCommand myCommand = new SqlCommand("GetAnswer", _productConn);
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.Parameters.Add("@QUESTION_ID", SqlDbType.Int).Value = QuestionID;
// check the connection state and open it accordingly.
if (_productConn.State == ConnectionState.Closed)
_productConn.Open();
// Sql datareader object to read the stream of rows from SQL Server Database
SqlDataReader myDataReader = myCommand.ExecuteReader();
// findControl function to get the nested datalist control
DataList nestedDataList = (DataList)dgQuestionnaire.Items[ItemIndex].FindControl("nestedDataList");
nestedDataList.DataSource = myDataReader;
nestedDataList.DataBind();
// close the Sql DataReader object
myDataReader.Close();
// check the connection state and close it accordingly.
if (_productConn.State == ConnectionState.Open)
_productConn.Close();
}
How can I get the value of a textbox when its corresponding button "updateName" is pressed?
Thanks
