Ok I have a fairly simple issue I want to define some session state variables
So far in my code behind in C# for an aspx page I have the following type of declaration working fine in my index.aspx.cs file.
Session[Constants.firstName] = "Jordan";
or
Session[Constants.firstName] = 123;
I want to grab the Text from the index.aspx Textboxes though instead like so.
Session[Constants.firstName] = txtb_FName.Text;
The problem is that changing this to the variable txtb_FName.Text does not work and when I debug it shows the local variable is being filled with "" not the input from my Textbox.
The whole CODE trail looks like this;

I have a an ASP.NET web form that needs to valid user input. However, upon entering invalid-user input the validation summary is not displaying. The weird thing was that it was working for a period of time and then now it doesn't show at all. Here is my code.

So i want to make a drop down list that displays new information if you select different radio buttons.
And im struggling.For Example if radio button 1 is selected the information in dropbox must change to popcorn and sweets.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<style type="text/css">
.auto-style1 {
margin-left: 18px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:RadioButton ID="RadioButton1" runat="server" OnCheckedChanged="RadioButton1_CheckedChanged" Text="Day" />
</div>
<asp:RadioButton ID="RadioButton2" runat="server" Text="Night" />
<br />
<br />
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>Cream Soda</asp:ListItem>
<asp:ListItem>coke</asp:ListItem>
</asp:DropDownList>
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="Name"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" CssClass="auto-style1" Width="139px"></asp:TextBox>
<br />
<asp:Label ID="Label2" runat="server" Text="Seat No:"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server" Width="140px"></asp:TextBox>
<br />
<br />
<asp:Button ID="Button1" runat="server" Height="20px" Text="Add Choice" />
<br />
<asp:Label ID="Label3" runat="server"></asp:Label>
</form>
</body>
</html>
You must define autopostback="true" on the RadioButton, and then you need to handle the selected value in the codebehind, and re-fill the drop-down with a new item-list.
Page-Cycle will be like this
Page_Load
RadioButton2_Changed
Page_LoadComplete
So make sure you either set the new content in RadioButton2_Changed, or in Page_LoadComplete. If you try to do it in Page_Load, you'll have the old value of radiobutton, and that will not work well ...
You can try the following steps to show the correspond information when you click the radio button.
First, you need to change your html file into the following:
<body>
<form id="form1" runat="server">
<div>
<asp:RadioButton ID="RadioButton1" runat="server" OnCheckedChanged="RadioButton1_CheckedChanged" Text="Day" GroupName="Ra" AutoPostBack="true" />
</div>
<asp:RadioButton ID="RadioButton2" runat="server" Text="Night" OnCheckedChanged="RadioButton2_CheckedChanged" GroupName="Ra" AutoPostBack="true"/>
<br />
<br />
<asp:DropDownList ID="DropDownList1" runat="server">
</asp:DropDownList>
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="Name"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" CssClass="auto-style1" Width="139px"></asp:TextBox>
<br />
<asp:Label ID="Label2" runat="server" Text="Seat No:"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server" Width="140px"></asp:TextBox>
<br />
<br />
<asp:Button ID="Button1" runat="server" Height="20px" Text="Add Choice" />
<br />
<asp:Label ID="Label3" runat="server"></asp:Label>
</form>
</body>
Second, you need to call the RadioButton1_CheckedChanged event and RadioButton2_CheckedChanged event to to add the listitem.
ListItem list1 = new ListItem("popcorn");
ListItem list2 = new ListItem("sweets");
ListItem list3 = new ListItem("Cream Soda");
ListItem list4 = new ListItem("coke");
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
if(RadioButton1.Checked==true)
{
if (!DropDownList1.Items.Contains(list1) && !DropDownList1.Items.Contains(list2))
{
DropDownList1.Items.Clear();
DropDownList1.Items.Add(list1);
DropDownList1.Items.Add(list2);
}
}
}
protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton2.Checked == true)
{
if (!DropDownList1.Items.Contains(list3) && !DropDownList1.Items.Contains(list4))
{
DropDownList1.Items.Clear();
DropDownList1.Items.Add(list3);
DropDownList1.Items.Add(list4);
}
}
}
Result:

You have to use the RowCommand event:
<asp:Button ID="btn_showComment" runat="server" Text="show comment" CommandName="ShowComment" />
And then from the code beside:
protected void gvPosts_RowCommand(object source, RepeaterCommandEventArgs)
{
if (e.CommandName == "ShowComment")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = ContactsGridView.Rows[index];
}
}

I'm getting a null reference exception on singleKingButton.Checked = true; in the page load event. If I comment it out then I still get one on the next line setting the date. The odd thing is the page loads fine it's when I hit the submit button that I get the error. Thanks in advance!

One of these all properties is receiving 'NULL' and at the time of inserting this values in database your table structure is not allowing 'NULL'.
So make sure that if you want to store 'NULL' in table then allow NULL in table structure (Table design).
You can check it using "line by line execution" of your code (using break point).
