Forms Data Controls ::DataList Within LoginView Loginview1.control Part Solve?
Sep 10, 2010
I've a datalist within the logged in template.On the page_load first I'm ensuring the visitor is logged in
[Code]...
[Code]...
However this doesn't work,I get the following error:Object reference not set to an instance of an object.
Highlighting:DataList1.DataSource = ds
If I take the loginview away then it works,but I thought the loginview1.findcontrol part would solve any problems.

I've put a DropDownList control within a LoginView control. I've got 2 SqlDataSource controls outside of the LoginView control, with the intent of databinding the items that comprise the ListItems of the DropDownList control, and another one for the data is stored in another table which has what was previously saved for the selection. However, when I've assign the SqlDataSource control to the DropDownList control's DataSourceID for the lookup table, I'm used to seeing the fields from the SqlDataSource control appearing in the DataTextField and DataValueField properties. However, they're not appearing there at all. Moreover, even when I try to type them in, its as if VS 2010 refuses to allow them.

Now that some of the Security matrix has been approved and site is somewhat more functional. We are going back thru adding the loginview to the pages that need it so we can control who can adn can't see the pages and data.
To keep it simple, here is what i have setup.. Because if this setup, i cant access my controls and the page wont display either template. Now even though the aspx code below is a very stripped down version of what i have, the code behind has references to controls that dont show in my example, but they are there in my actual page. I Just removed alot of information to make the post more clear.

I cannot dig out the controls correctly in my code, as they are hidden in a datalist. I am trying to update some data into a row in the 'resume' table. Is INSERT INTO corrent for updating data which is already there?
and also i cannot find the controls in the datalist correctly....?
protected void LinkButton2_Click(object sender, EventArgs e)
{
string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
System.Data.SqlClient.SqlConnection sqlConnection1 =
new System.Data.SqlClient.SqlConnection(connectionString);
System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = "INSERT INTO resume (confirmed,comment,reference) VALUES (@confirmed,@comment,@reference) WHERE number = @number";
cmd.Parameters.AddWithValue("@number", DataList1.FindControl("picturesLabel0").Text);
cmd.Parameters.AddWithValue("@confirmed", DataList1.FindControl ("RadioButton1").SelectedValue);
cmd.Parameters.AddWithValue("@comment", DataList1.FindControl ("TextBox3").Text);
cmd.Parameters.AddWithValue("@reference", DataList1.FindControl ("TextBox4").Text);
cmd.Connection = sqlConnection1;
sqlConnection1.Open();

I have a datalist that displays text which links to another page. Depending on which value is selected the data shows the relevant data for the selected record. Using the code below I have tried to insert the 'RecId' value into the url to get the correct data but I get an error because the syntax is wrong.
<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" ShowFooter="False" ShowHeader="False">
<ItemTemplate>
<asp:HyperLink ID="EventDescLabel" runat="server" NavigateUrl=http://www.MySite.com/Courses/tabid/98/ModuleID/509/ItemID/" & '<%# Eval("RecId") %>' & "/mctl/EventDetails/Default.aspx"
Text='<%# Eval("EventName") %>' />
</ItemTemplate>

I have a LoginView control that contains a PasswordRecovery control. Upon page_load I don't want this to be visible. When the user clicks a hyperlink button ("forgot password?" type of button), then it'll be made visible.
But I'm having a hard time making the password recovery control invisible at runtime. Here is my page_load function:
[Code]....
It is the only password recovery control in the LoginView control, so I don't understand why this isn't working. The password recovery control is still visible when the page loads in my browser.
