Forms Data Controls :: Turn Null Cells In A Gridview Into Zeros?
Jul 7, 2010
I have a Gridview with some cells in numbers while in some cell they could be null without numbers. I need to modify it such that the numbers in the Gridview are in these formats:-
(a) If it is 12345.333 becomes 12,345
(b) If it is blank, I wish the cells to display 0
This is the code I am using to achieve (a), but when it comes to blank, it returns error (I believe my code below failed to provide blank cases but I dunno how. So what should be the code to do (b) above ?
For i As
Integer = 1
To N
e.Row.Cells(i).Text = String.Format("{0:#,##0}", Convert.ToDouble(e.Row.Cells(i).Text))Next
I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?

I realized this has been asked multiple times before, but I still haven't been able to get it to work. I'm trying to export a Gridview to Excel without losing leading zeros. Here is my code. Add added the STYLE lines to try to fix the problem.
Dim attachment As String = "attachment; filename=Awards.xls" System.Web.HttpContext.Current.Response.ClearContent() System.Web.HttpContext.Current.Response.AddHeader("content-disposition", attachment) System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel" Dim sw As New StringWriter() Dim htw As New HtmlTextWriter(sw) gv.RenderControl(htw) System.Web.HttpContext.Current.Response.Write(sw.ToString()) Dim STYLE As String = "<style> .text { mso-number-format: ; } </style> " System.Web.HttpContext.Current.Response.Write(STYLE) System.Web.HttpContext.Current.Response.[End]()
I have a Gridview and I allow fullscreen editing. I have some RequiredFieldValidators in my Gridview and this works fine. But if the user clicks on a dropdownlist in the Gridview and chooses "Rejected", I want to turn off validation. But I am not sure how to do this. Here is my code in the SelectedIndexChanged event for the ddl:
Protected Sub ddlPOACKCodes_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
[Code].....
But I get an error on this line: rfv = gvPODetail.SelectedRow.FindControl("rfv11"). the error is:
Object reference not set to an instance of an object.

I'm working on a project in vb.net framework 2.0 and have a column that has server names. I have the accessdb sql setup to order by the db, what I would like to do is to have it look like the following picture below. I'm pretty stumped on how to do it as the methods I've found online haven't worked so well. Also just a small tid-bit the gridview is bound to a ddl which selects the application and the gridview refreshes with server data. Country would be server name and state would be the environment.

we're creating a GridView to display news articles programmatically (not using a SQL database).
We can create & display the GridView, but are having a devil of the time to get the hyperlinks in SetupGrid() attached to the titles
of the articles in the GridView. Below is our .aspx code and .vb code of how we create the GridView. Any ideas on what we should do to get the hyperlinks array of strHyperlinks() in SetupGrid() to be applied to the titles in column 1 of the GridView?
I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.
I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I have a GridView known as GV_R001 with IssueType, ActID, IssueID cells. I want to Merge the similar IssueType cell accordingly. How do i merge and also sort the IssueType cell accordingly. The following is my codes:
Protected Sub GV_R001_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GV_R001.DataBound For rowIndex As Integer = GV_R001.Rows.Count - 2 To 0 Step -1 Dim gvRow As GridViewRow = GV_R001.Rows(rowIndex) Dim gvPreviousRow As GridViewRow = GV_R001.Rows(rowIndex + 1) Dim cellCount As Integer = 0 If gvRow.Cells(cellCount).Text = gvPreviousRow.Cells(cellCount).Text Then If gvPreviousRow.Cells(cellCount).RowSpan < 2 Then gvRow.Cells(cellCount).RowSpan = 2 Else gvRow.Cells(cellCount).RowSpan = gvPreviousRow.Cells(cellCount).RowSpan + 1 End If gvPreviousRow.Cells(cellCount).Visible = False End If Next End Sub
Apart from that, after sorting i want to calculate the amount of IssueID are in a particular IssueType and display in a cell called "Total". Is it possible to do so? By the way, I am using Web Developer 2008, VB.net.
I'm looking for a technique to edit a whole column (vertical) instead of a row (horizontal).Suppose i have 10 rows en 5 columns (like in Excel), and i want to edit all digits from different students (rows) for test number 3 (column).
One column in my GridView has the format 1-2345 (one digit followed by a dash followed by four digits. Normally, everything looks OK, but sometimes the other data in my GriView will expand to two or more "lines" in the same row of data. Unfortunately this causes my cell to look like the following:
1- 2345
This looks really really awful and I need to fix it. You know how in HTML there is the non-breaking space symbol? Well I want a non-breaking dash symbol.
