I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I have Gridview like this:
<asp:GridView ID="gvPartsSearchResult" runat ="server" CssClass="MRJ_TextGrid">
<Columns>
<asp:TemplateField HeaderText="Select">
<ItemTemplate>
<asp:RadioButton
ID="rdButton"
runat="server"
AutoPostBack ="true"
onclick="javascript:CheckOtherIsCheckedByGVIDMore()"/>
<asp:HiddenField
ID="hdnFileExtension"
runat="server"
Value ='<%#Bind("FILE_EXTENSION")%>'/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I want to read the hidden field value when the user clicks on the radio button.
I have the code below that works fine, but I need to have more than one field using the same command.

I am trying to set the value of a hidden field onblur. I add the blur attribute programatically on page load. When the user moves off the control the blur event fires the following javascript.
function getFocus()
{
var obj=document.activeElement;
alert(obj.id);
[code]...
int no = int.Parse(hidden_field.Value.TrimStart()); it cause the error: input format was not in correct format. how to fix it?

What is difference between ViewState and Hidden Field in ASP.Net. If possible with an example.
View 1 RepliesFrom the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?

I got the difference between Bind and EVal from here. Bind will do both way reading and writing. And Eval do only reading. So any function only for writing?

I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:
tst = document.getElementById('control1$hdnField').value;
I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also confirmed that the hidden field by this name exists in the user control and also has a default value set.
have a tree view control build dynamically. i want to change color of the selected node from client side. write the script given below. and its work fine.

I can't get this to work:
I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.
[Code]....
While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read
[Code]....
so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.
[Code]....
so, while debugging, lblImp.Text = "";
why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.
I have the following Repeater, I need to bind multiple querystring parameter in HREF
<li class="current">
<a href="house.aspx?H_name=all"></a>
<ul>
<asp:Repeater ID="rptMenu" runat="server">
<ItemTemplate>
[code]...
here my code-
<asp:TemplateField HeaderText="HIGH RISK (10-12)" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblHighrisk" runat="server" Text='<%# Eval("URANGE").ToString().Split('-')[0] %>' />
</ItemTemplate>
</asp:TemplateField>
but that is giving compile time error 'Server tag is not well formed'
I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

I've got a gridview with a hidden field, i'm trying to set a value as follows:
value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'
which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.
so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and
value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'
which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.
This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '
i have one hidden field and i want to bind it with two values of my data base separated by an coma. some thing like
->asp:HiddenField ID="hfRstidDate" runat="server" Value=<%# DataBinder.Eval(Container.DataItem, "tsk_ID"),DataBinder.Eval(Container.DataItem, "Date_Worked").ToString())%>
I want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post. Inside that form there are some hidden input filed. I want to assign one of those hidden field's value from server side code so i need to access that filed from server side. But how? Here is my form:
<form action="[URL] method="post" id="PaypalForm">
<input type="hidden" name="cmd" value="_cart"/>
<input type="hidden" name="upload" value="1"/>
<input type="hidden" name="business" value="[URL]
<input type="hidden" name="item_name_1" value="Item Name 1" />
<input type="hidden" name="amount_1"/>
<input type="submit" value="PayPal" />
</form>
I want to access amount_1 filed.
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
IF statement which I use to validate the value in EVAL("field").
Here is my code in .ASPX
