I have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).

I have a validator that check an input.
i what that the validator displayed "valid" if the value is valid, and "invalid" if the value is hasnt passed the validation.
can manage without adding an additional label for the valid state(by setting the visibility: true/false)?
does the validator control has am alternative value, or i have to override it?
Basically, when the page loads i set the div visibility to false. When i click the button, i want the code behind function to be called, and the div tag to be visible, true.
$('#Button2').click(function () {
$('#edit').show(function () {
});
});
<input type="submit" id="Button2" runat="server" value="Search" OnServerClick="Button1_Click" />
but when clicking the button, the page posts back, causing the div tag to be invisible all times.
I can set the return false to the onlclick event of the button , but i need to call the function also.

How to check the field value which is assigned to the text box is empty or not.
I need to set the visibility of the text box to false when the field value is empty.
I have an user control which contains a textbox.... I want to first display it false inside usercontrol and then visible it at the calling page.
note that the textbox id is generated dynamically.
I have a div in checkout.aspx page. The contents of div are as follows:
<div id="PaymentDetails" runat="server" style="text-align:center" visible="true">
<asp:Label ID="PaymentDetailsLbl" Text="Payment Details:" runat="server" Font-Size="Large"></asp:Label>
<br />

So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.
Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.
What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:
<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>
In the Row Command event handler, here is how I am setting the visibility of the button:
If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If
The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.
Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.
If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?
how do i check if a bit value is true or false and if false, then write another value.
Here is my code
<%# DataBinder.Eval(Container.DataItem, "gp_referral").Equals("False")?"":"xxx"%>
Am trying to check if gp_referral is false, and if so then write xxx, but in my code, whether true or false it evaluates to xxx
i have a grid view with all columns as TemplateFields( No BoundField). Based on certain condition i have to set Visibility of few columns false. Suppose when there is no column 'CaseList2' in the DataTable, then the second column of the grid (whose column index is 1 )should be invisible. But when the Gridview binds it gives error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'CaseList2'
i googled it and found that
GridView1.Columns[1].Visible = false;
should work. But its not working actualy.
Code:

I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.

I have a ListBox which is bound to a list of data items.
Now I want the user to be able to filter the items shown in the ListBox based on the search expression typed in the TextBox. For each character typed in the TextBox, the ListBox items should change to show only the items matching the search expression.
I have a databound dropdownlist hooked up to a table and the query has the returned items show up in order. I also have some default items that are _DataBound like so:
[Code]....
What I'd like to do is add some more items, but have these new items show up in order with the other items displayed from the query. How do I accomplish this?
How do you avoid duplicate bound items in this scenario: There's a databound control on a page (a DropDownList in this case, though I don't think it matters). It has AppendDataBoundItems set to "true". Somewhere in the code, a DataSource is set and DataBind is called. So this control is bound explicitly. You have a bunch of other things to bind on the page, so you call Page.DataBind.
Your databound control now has duplicate items in it. It was (1) bound explicitly, then (2) Page.DataBind bound it again. Since AppendDataBoundItems was true, the second bind appends to the first, and you end up with double the items. A couple limitations: The explicit call to DataBind on the control is done through some centralized code, and would be painful to change. i really need to bind the rest of the page in aggregate (via Page.Databind()) because there's too many other databound elements to do it individually without writing a ton of individual calls.
I need a method like... Page.DataBindExceptIfTheyHaveAlreadyBeenBoundDuh()
I have a site that will not use theming. But by default the value is set to true. Does ASP.NET do a check everytime to see if I'm using themes. Is there a performance hit?
View 2 RepliesI have two databound listboxes. I am able to move items between them using add and remove buttons using for loops. However I have no idea how to commit the items back to the db when the user finally clicks on the Save button on the form.
View 5 Replies I have a DDL bound to a sqlDataSource, and I want to insert an item in the first position. I tried using this code in the onDatabound event:
Protected Sub ddl_onDataBound(ByVal sender As Object, ByVal e As EventArgs) Handles ddl.DataBound
ddl.Items.Insert(0, "None")
End Sub
But when I load the page, the item "None" is inserted twice at the beginning of the DDL? So I see something like:
None
None
item1
item2
Do I need to put the items.insert somewhere else, like on the pageLoad, to avoid it being executed twice, or am I doing something really wrong?

View 7 RepliesI have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?
have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...
i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.
The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)
