I have set HiddenField value from jQuery and i want to use this HiddenField value in page_init event, but each time i get blank value. what would be the issue.
$('#hfKitchenID').val(kitchenid);
protected void Page_Init(object sender, EventArgs e)
{
string value = hfKitchenID.Value;
}
On
I would like to suggest you that please use Request in Page Init event to get the value of hiddenfield control.
Please check the sample below ,hope it can help you.
1.Code in page(.aspx):
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server">
<title></title>
<script type="text/javascript" language="javascript">
function SetValueToHidden() {
var hidden = document.getElementById("HiddenField1");
var text = document.getElementById("TextBox1");
hidden.value = text.value;
}
</script> </head> <body>
<form id="form1" runat="server">
<div>
Input text:<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
<asp:Button ID="Button1" runat="server" Text="ShowText" OnClientClick="SetValueToHidden()" />
<asp:HiddenField ID="HiddenField1" runat="server" />
</div>
</form>
</body>
</html>
2.Code in page(.cs):
protected void Page_Init(object sender, EventArgs e)
{
if (Request["HiddenField1"] != null)
{
Response.Write(Request["HiddenField1"].ToString());
}
}
You cannot get the value of the hidden field on
Page_initbecause the value of the hidden field is save inViewState, andViewStateis not accessible onPage_Init.In the page life cycle the
LoadViewStateEvent occurs just after theInitEvent.
