Forms Data Controls :: Gridview Header Formatting?
Sep 22, 2010
HUsing C# to develop a web application. Have a gridview to display data from the a sql table.The headers of the gridview is achieve using a table. Need to format the header cells to align with the columns of the gridview.Currently I'm using a trial an error method to set the width of the header to align with the gridview columns. Can I align the Table header to concide with the gird view column width progarmatically?
I have a Gridview with certain columns header in form of dates (coz the datasource is with column field from a date field in a cross tab query). What will be the code of databound event that convert col labels from like 6/1/2010 to Jun-10 in the header text.
I want if the header of a particular column contains a word "S", the header and row turns red. I used following code to make header red and it works fine. How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)Dim HeaderRow As GridViewRow = GridView1.HeaderRowFor Each c As TableCell In HeaderRow.CellsIf c.Text.EndsWith("S") Then c.BackColor = Drawing.Color.OrangeRed End If Next End Sub
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,
formatting a gridview where I have some numbers that show up with the minus sign on top of the number.Ideally I'd like to set the negative numbers to be red if you know how to do that.I'd also just like more control over the width of the columns.some of my formatting code is below. The If - Endif stuff fails with a null reference exception, but the forecolor and backcolor and align code works
i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).
I need to add a check for a checkbox column in the grid. Something like:If CDate(e.Row.Cells(6).Text) < Date.Now and 'checkbox is checked' Then make another colorHow do I check for the value of the checkbox?
I have a gridview on my aspx page. I know we can format gridview row in rowdatabound() of gridview. But my problem is bit different.
In my gridview, i have a column customer code, a single code can repeat more than once successively. I want for one customer code, row color should be blue and as soon as code changes colour should be yellow for that code. Similarly when code changes again color should be blue again.
In this way color of my gridview rows should be blue and yellow alternately based on my customer code.I have arranged customer code in order by using sql order by clause.
I am using a column named "bk_End_Date" in my gridview.I want to change the row color based on a condition.i.e. if the date value is within one week of today's date (upcomming days only), it's color should be red.I tried following method in RowDataBound Event of C#
I've got a Gridview in which I have a column that shows percentages. I use the 0:P2 to format the percentage into readable format. However when the user 'edits' the particular row the percentage sign % still shows up in the textbox. When the user tries to save/update their change I throw an error on the % sign.
Is there a way to show the % only when the row isn't in an editable state?
I'm displaynig plain text in a Gridview and the format is not the one I'm looking for here's what's happening. The data in the database (SQL) is store as sample1

1. text here and more text 2. blah blah blah 3. more text, etc
However in the Grid view is displayed like this:
Sample 2:
Please do the following: 1. text here and more text 2. blah blah blah 3. more text, etc
specially VB code behind pages.I am writing an app with a colleague and I am stuck on something.he app is a holiday booking calendar. I have a gridview that shows the total number of days booked for each month of the year. When you click the cell for say January another gridview is populated below showing each day of january.My problem is that I want to change the formatting of the cells in the second gridview depending upon if any of the cells have a 1 or a 0.
This will create multiple fields in the gridview with some values. Say i have this field called "Sold" and it has the value "1234.5600" How can i display it like "1,234.56" ?
I have a Gridview which is autocolumngenerated so the column can be numeric or text depending on what the datasource returns.I want to format it such that :If the cell/column is numeric, then format it into sth like 3,331.How to write code to detect this and do the job ?
I have a Gridview with autogenerated columns since the query structure keeps changing depending the dropdown list.
However for Jan-10 etc column I want to format it to #,##0 etc. I use Dataformatstring when hard code the column but for autogenerated column, what can I do ?
I know one way is in script databound event make it that format whenever header = Jan-10 etc. What should be the code?
I have parentGridView and childGridView. ChildGridView opens in ParentGridView cell. But it expands the cell and makes all the parents cells out of formatting look and feel.1 ) How can i use colspan property to expand the childGirdView? 2) i am using find control in codebehind, i dont want to disturb that hierarchy as well
