Gridview - Setting Column Header's Css Class From Code Behind

Jan 20, 2010

what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.

Setting Visibility Of Button Control In GridView Header?

Nov 8, 2010

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?

Forms Data Controls :: Setting GridView Header Text When Page Changes?

Feb 6, 2010

I have a GridView (inside an update panel) that has header text that changes based on some user profile information. I set the header text in the Page_Load function of the page - that works fine. The problem is that when I change to the page number of the GridView, the header text is not redrawn. I am handling the OnPageChanging event to try to update the header text but nothing is happening. I've attached the relevant code.

Gridview - Adding Column Of Checkbox To Its Header

Jul 22, 2011

I edited my gridview template by adding an additional column of checkbox and to its header

I managed to do a checkchange for select all or none and for selecting single of multiple checkbox.

My problem here is that when I try to select all, uncheck another checkbox, the header checkbox is still checked and the unchecked checkbox becomes checked again.

If i did not check my header checkbox and just check it normally, its fine.

Forms Data Controls :: GridView Disappears When Click A Column Header To Sort?

Jul 28, 2010

I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.

When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.

I don't understand why the GridView is disappearing when I click a column header.

Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

Forms Data Controls :: Setting The Color Of A Column Heading On A GridView?

Jun 16, 2010

I have sutmbled across somethig strange. When you ser theYou cannot set the color in a style and apply it to the heading of a grid, it will show in the templated columns, but not in the non-templated columns.

You can set the color for the non-templated columns with the HeaderStyle-ForeColor attribute, but it seems strange for it not to recognize the color in the style and seems redundant to have to specify a style and a color seperately.

Am I doing somethign wrong. Is there some sort of setting I have wrong that is causing this?
