I have following
<input type="hidden" id="hdnField" name="hdnField"/>
Request.Form.Set("hdnField", x.ToString());
after the page post back the value is not there.
I am new to this, any help would be appreciated.
You could define a property in your page class and then modify the property value in your code:
protected string HiddenFieldValue { get; set; }
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
HiddenFieldValue = x.ToString();
else
HiddenFieldValue = x.ToString();
}
Then define the hidden form field like this so that it's value is set to the property value:
<input type='hidden' id='hdnField' value='<%=HiddenFieldValue %>' />
If you only want to set the value form the property during a postback or non-postback you could add the condition as well:
<input type='hidden' id='hdnField' value='<% if(IsPostBack) { %> <%=HiddenFieldValue%> <% } %>' />
You should use asp:HiddenField
tag provided by asp rather than using the basic HTML input.
<asp:HiddenField ID="hdnField" Value="" runat="server" ClientIDMode="Static" />
Using this, you can read and write value in c# using hdnField.Value
and in jQuery using $('#hdnField').val()
.
