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 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?
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'
we're in the process of trying to speed up the performance of our website by serving static content from a cookieless domain. That seems to be going well, but I have a new question:
I know that it's "static content" that we're talking about when serving it from a cookieless domain, but we also have static content being served by ASPX pages, specifically images. For example:
I have a web page where a div needs to be displayed under certain conditions. I'm using the following code to toggle the display and have verified that it works.
[Code]....
To call this javascript function, I'm using the following code in the code-behind for the page:
[Code]....
I traced the flow using the debugger. When the page load, txt_Cat_ID.Text = "2" correctly resolves to FALSE and the toggleOptionsDiv script is run with the 'hide' parameter. The page correctly hides the div.
When I click on the link that makes txt_CAT_ID.Text = "2" resolve to TRUE, the code executes the line where the toggleOptionsDiv script is run with the 'show' parameter. However, the div remains hidden.
The link that is clicked triggers an asynchronous post back and I'm not sure if that is the problem. How can I get the div to display on postback?
I have a webform containing a user control. On that user control is a set of radio buttons. When the radio button is changed, a panel and a text box is shown or hidden depending on which radio button was selected.I can give you an example that works correctly:testcontrol.aspx:
How can I call a public property declared on a ASPX page from a different ASPX Page? Is that possible? It is a website project. How can I get/call this property from a different aspx page? I have attempted this from the other page, but it is not recognizing the partial class: private Test_Default _test; It does not recognize the "Test_Default"
I have an aspx application with 2 aspx pages. Second aspx page will get opened on click of a button in first aspx page using JavaScript. The problem is, when the second aspx page is getting opened, its Page_load event is not firing. Only when I refresh the second page, page_load event of second aspx page is fired. what might be the problem and what is to be done to fire the page_load event.
I wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?
I have page A.aspx where I show some result in listview. When I click On Some data on listview I go to page B.aspx.

How do i do that?
I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
