Custom Server Controls :: How To Remove The Border From Gridview Header
Sep 24, 2010
I have created a custom gridview that show "Select All | Clear All" hyper links in header to select the checkboxes in the gridview. That means that I have added these two hyperlink controls to the gridview header and am not showing the actual column headers.
[Code]....
Now, I want to remove the border that is displayed on the header row. How can I remove it? I tried th.BorderStyle = BorderStyle.None; but it didn't work. I need gridlines in the data rows but the header row should not have any border.

Scenario: I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header. I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
I have extended a gridview to add an additional header with following two hyperlink controls "Select All" and "Clear All". These will operate on checkboxes in the data rows of the grid. I hide the column headers as I only want to show one column with checkboxes and "Select/Clear All" links. Everything is working as expected. Now, I wanted to add a scrollbar to my grid control, I did add the scroll bar using div but what it does is, it includes the "Select All and Clear All" links aswell. I only need to add the scrollbar to datarows and not to the header.I am trying to extend my control to include hte scrollbar by adding div during Render function. But how will I determine or loop through header rows? How will i get the header row with hyperlinks that I created above?? In Render if I do this.HeaderRow, it gets the original column header and not the custom header.
i have a gridview that directly bind to a dataset.Hence there is no column in code behind for me to control the boarder color and border style.I try my code in RowDataBound, but it does not take effect.
I have a datarepeater inside which I load a gridview. After the grid's binding is done I create an extra header line to group the columns (that's the only way I could do it, I couldn't figure a way to add an event for a control inside the repeater).That works fine and the page displays perfectly.However everytime I do a postback from other controls, I lose the 2nd header and 1 extra empty line appears at the top of the gridview
In SSRS 2005 I could select the header row of a table and in the properties window, expand the BorderStyle property and type Solid in the Bottom property and I would get a border at the bottom of the row containing my column headers. In SSRS 2008 I cannot do this. If I select the header row, the BorderColor, BorderStyle and BorderWidth properties do nothing when you expand them. If you try typing into them you get an error: "Property is not valid." So I selected the header textbox for one column and tried adding the bottom border to it, thinking that I might have to set each column individually, but the border does not appear for that column heading.
I'm using a <asp:Login> control and it's automatically putting CellSpacing, CellPadding, and Border attributes into the generated HTML table. How can I stop ASP.NET outputting these attributes (without moving to ASP.NET 4)?
I'm have a project that uses a TabContainer. When I view the TabContainer from my local IIS it displays fine. When I run this from a production environment I'm getting tiny gap & a border line below my TabPanel Header. My browser is IE 8.0
I have existing project written by someone else that utilizes custom User Control that among other things contains a GridView control.I'm working on implementing the bulk-edit function so that users can modify data in many rows at once and then update the database accordingly.My problem is that in all examples that I see in order to implement this functionality you need to Override the CreateRow method, at which point you are able to put it in Edit State. The issue is that since my custom control inherits from User Control and not from GridView this protected method is not available. If I change the inheritance to GridView, tons of other things break inside this code, so I'd like to avoid that.My question is, is there anyway to still override the CreateRow if I'm inheriting from UserControl class and not GridView.If this is not very clear, please let me know and I'll try to explain further. I really need help with this, as it is time sensitive and it's always hard to work with someone elses code,
I have custom gridview that inherit from the regular gridview.
On of the features is that is has a built in page size dropdown in an extra header row.
Another feature is that this extra header row has a place holder where aditional controls can be added but here is where I have some problems.
When I add a control that is created outside the gridview to the gridviews builtin placeholder and tries to do anything that performs a postback the gridview dissepears, but appears again on a new post back.
Here is the code for the gridview:
[Code]....
And this is the way it is used in a usercontrol on page, the gridview is called gvList and the control that I try to add to its placeholder is the phrExtraHeaderControls:
[Code]....
What can be wrong, is the viewstate messed up in the postback so that the gridview can't be rendered?
