<asp:HiddenField ID="mypostID" runat="server" Value=""/>
I wanted to ask if I could do something like:
<asp:HiddenField ID="mypostID" runat="server" Value="<% Response.Write(Session["ïd"])%>"/>
I cannot access the session from the user control code behind but if I put a Respose.Write on the page itself it shows the session value.
I want to set the "name" attribute for HiddenField control of ASP.NET from code behind, but I cannot find the "Attributes" property. Is it not there for a purpose? How do I add the attribute
View 2 RepliesI have a for which is built within an ASP.net usercontrol. This form is then used within a CMS as part of integration with a merchant gateway. The gateway requires that a number of hiddenfields be passed in which is fine in the main however one of these needs to be called Profile. The CMS I am using also defines a global variable called Profile and as such when I try and add a hidden field with this ID I get errors.
Is there a way of setting the 'name' property to Profile, and the ID to something different?

I already have the jQuery function that someone in this forum gave me a couple weeks ago, it is working perfectly fine. The problem I have is that I don't get the value of the BoundField that is visible =False I just get the closest BoundField value of the index that I request (the next of the hidden one).

Looks like the "asp:HiddenField" doesn't have an "AutoPostBack" property, and I'm having problems with the "OnValueChanged" event... I need to call a function (C#) when I populate the hidden field, but in my case nothing happens. And I cannot use any scripts.

I have been at this for two weeks now without any success but I know I have to get a solution to move forward with my design. Is there any way to bind data from a SQLDataSource to a Hiddenfield or Textbox WITHOUT binding via the data controls like gridview, formview, datalist, etc. I do not want to use any of those controls. I need to do inline binding. Please provide the working code example. The hiddenfield or textbox would be named eid. The SQLDataSource name is GetDataEid. Again, if you reply and you submit code I can try please provide the full working solution. These do not work. They have already been attempted:
<asp:HiddenField ID="HiddenField1" runat="server" Value="<%#Container.DataItem("FieldName") %>" />
<input type="hidden" id="hdnId" name="hdnId" runat="server" />
and write the following code in your page load method
hdnId.Value=yourDbValue.ToString();
asp:HiddenField ID="hid" runat="server" Value='<%#Eval("column name") %>' />
i need to be able to reset a HiddenField's value if my AutoCompleteExtender returns no results (specifically, if the user searches for something that's not in the list/database). I have this JS code now:
[Code]....
How would I modify this to check if the list is null? Currently it seems to just leave the value as it was previously.
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="HiddenFieldTime" runat="server" Value='<%# Bind("Time") %>' Visible="False" />
</ItemTemplate>
</asp:TemplateField>
