You can not access Session object in Javascript as it is a Server object.
Here [^]is a nice article explaining how to write client side variables in ASP.Net

If you are trying to access lblLoginId.Text from client side, then what is need of session over here. You can try just using reading the ClientID of that control.
You can't Directly Access Session Variable from javascript. You can store it in a hiddenField and then can access from Client Side.

thanks...
but when i store it in a hiddenField then i use runat=server .......so it can't accessible in javascript. or if use hiddenField witout runat=server then it can't accessible in codebehind.......
so what i do?

Leave it as Runat="Server"
Then
var HiddenFieldID="<%=hdnField.ClientID%>";
var HiddenFieldValue=document.getElementById(HiddenFieldID).value;

There are Two ways
1. Using Classic Asp Tag to fetch the Session Variable
var cal = <%= Session("LoginID") %>
2. You can make a AJAX call to server to fetch the Value stored in Session Variable
|
|
|
|
|
Try this -
var lgnId= '<%=Session["LoginId"]%>'
|
|

no,no,no,no.......
I have seen this code in a couple of dozen posts and it NEVER works.
My situation
ASP .NET 3.5
C# code doc.aspx.cs
...
...
Session["UID"] = "1234";
Javascript doc.aspx
var uid = <%=Session("IUD")%> NO
var uid = '<%=Session("IUD")%>' NO
var uid = "<%=Session("IUD")%> NO
var uid = <%=Session([IUD"]%> NO
var uid = '<%=Session["IUD"]%>' NO
var uid = "<%=Session["IUD"]%>" NO
I think the code below would work but I'm not sure how to code the client side
C# code
HiddenField hUID.value = Session["UID"];
Javascript
????????????????
I'm pretty frustrated after several hours of trying to get this to work. A working example of code would be HIGHLY appreciated.
Thanks,
Joe B

I want to hide the cursor or make the blinking cursor stop blinking in the asp.net textbox. Is that possible??
|
|
|
|
|
You cannot hide the cursor. If you have set the ReadOnly=True then it will not not let user write anything. But cursor blinking will appear by default. Alternatively you can set the property TabStop=False. Then cursor will not appear by default in Rich text Box. But if you click in the Rich Text Box the cursor wil blink. But it will not let user edit as you have set ReadOnly=True

no normal HTML input text cant do. Well, why not u use Span to do that, when user types in the document, just update the span. This way you can only do this, but I dont think it is a better option to do.
Otherwise you can hide cursor if the textbox is within a Flash object. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Hi,
u can do from client side,
function fnnotnull()
{
if ((document.GetelementId("<%= txtCredit.ClientID %>").value <> "") && (document.GetelementId("<%= txtdebit.ClientID %>").value <> ""))
{
alert("Msg here");
return false;
}
}
u can call this in a button onclientclick event

I guess, you directly write the code over here
Small Correction,

getElementById

As an improvement to this, you may want to wrap this javascript into a custom validator and include server side validation also.

The code is tested .
<asp:ListView ID="ListView1" runat="server"
onitemdatabound="ListView1_ItemDataBound1">
<LayoutTemplate>
<table border="0" cellpadding="3" cellspacing="0" width="97%">
<tr class="lstheader">
<td width="15%">
Col one</td>
<td width="15%">
Grid Column</td>
</tr>
<asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr >
<td>
<asp:Label ID="lblDate" runat="server" Text='<%#Bind("DepartmentID") %>'></asp:Label>
</td>
<td>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Department" DataField="Department" />
</Columns>
</asp:GridView>
</td>
</tr>
</ItemTemplate>
<AlternatingItemTemplate>
<tr >
<td>
<asp:Label ID="lblDate" runat="server" Text='<%#Bind("DepartmentID") %>'></asp:Label>
</td>
<td>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Department" DataField="Department" />
</Columns>
</asp:GridView>
</td>
</tr>
</AlternatingItemTemplate>
</asp:ListView>
now firstly Bind the ListView Control as below
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
fillgrid();
clsDepartment dpt = new clsDepartment();
ListView1.DataSource = dpt.SelectAll();
ListView1.DataBind();
}
}
Implement the ItemDataBound event of ListView and Find The Gridview. After Finding bind it
protected void ListView1_ItemDataBound1(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
GridView Grd = e.Item.FindControl("GridView1") as GridView;
if (Grd != null)
{
clsDepartment dpt = new clsDepartment();
Grd.DataSource = dpt.SelectAll();
Grd.DataBind();
}
}

onitemdatabound="ListView1_ItemDataBound1">
<LayoutTemplate>
<table border="0" cellpadding="3" cellspacing="0" width="97%">
<tr >

</tr>
<asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr >
<td>
<asp:Label ID="lblDepartmentID" runat="server" Text='<%# Bind("DepartmentID") %>'></asp:Label>
</td>
<td>
<asp:LinkButton CausesValidation="false" ID="lnkexp" runat="server">+</asp:LinkButton>
<asp:LinkButton CausesValidation="false" ID="lnkCol" runat="server">-</asp:LinkButton>
<asp:Label ID="Label3" runat="server" Text="panel"></asp:Label>
<asp:Panel ID="pnl1" runat="server" >
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Department" DataField="Department" />
</Columns>
</asp:GridView>
</asp:Panel>
<cc1:CollapsiblePanelExtender ExpandControlID="lnkexp" CollapseControlID="lnkCol" TargetControlID="pnl1" ID="CollapsiblePanelExtender2" runat="server" TextLabelID="Label3" ExpandedText="collapse" CollapsedText="expand" SuppressPostBack="True" Collapsed="True">
</cc1:CollapsiblePanelExtender>
</td>
</tr>
</ItemTemplate>
<AlternatingItemTemplate>
<tr >
<td>
<asp:Label ID="lblDepartmentID" runat="server" Text='<%# Bind("DepartmentID") %>'></asp:Label>
</td>
<td>
<asp:LinkButton CausesValidation="false" ID="lnkexp" runat="server">+</asp:LinkButton>
<asp:LinkButton CausesValidation="false" ID="lnkCol" runat="server">-</asp:LinkButton>
<asp:Label ID="Label3" runat="server" Text="panel"></asp:Label>
<asp:Panel ID="pnl1" runat="server" >
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Department" DataField="Department" />
</Columns>
</asp:GridView>
</asp:Panel>
<cc1:CollapsiblePanelExtender ExpandControlID="lnkexp" CollapseControlID="lnkCol" TargetControlID="pnl1" ID="CollapsiblePanelExtender2" runat="server" TextLabelID="Label3" ExpandedText="collapse" CollapsedText="expand" SuppressPostBack="True" Collapsed="True">
</cc1:CollapsiblePanelExtender>
</td>
</tr>
</AlternatingItemTemplate>
</asp:ListView>
And change to item databound will be as follow
protected void ListView1_ItemDataBound1(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
Panel pnl = (Panel)e.Item.FindControl("pnl1");
if (pnl != null)
{
GridView Grd = pnl.FindControl("GridView1") as GridView;
if (Grd != null)
{
clsDepartment dpt = new clsDepartment();
Grd.DataSource = dpt.SelectAll();
Grd.DataBind();
}
}
}
}
Now Apply Images and Styles yourself

Hello,
I am having a table in my databse with columns
ACCOUNT_CODE NARRATION
i filled dropdown list with account code values from the database.
now my question is:
when i select the p[articular item in the dropdown list,
the narration textbox must be filled from the database based on the
selected item.
Plz,help me....
Thanks in advance

Did you struck somewhere ? You said you have added values from the database to dropdownlist.
In DropDownList1_SelectedIndexChanged event, you can write code for creating textbox dynamically, bind it with database value and add it to the form.
Dim txt As New TextBox()
txt.Text = "Sample value from the database"
Me.form1.Controls.Add(txt)
Make the controls AutoPostBack property as "True".
