ADO.NET :: Generating Blank Rows On OnCreated In Another Table?
Nov 27, 2010
I am using Linq to create a schedule, which includes columns for creation date, modified date, isSubmited, UserId. Anytime that the schedule is created, I would like to automatically add rows to the ScheduleDays table, which has columns for scheduleId, date, etc.
Currently, I am trying to extend the OnValidate method as follows:
Partial Public Class Schedule
Private Sub OnValidate(ByVal action As System.Data.Linq.ChangeAction)
Dim day As New ScheduleDay[code]....
This code does not work. Rather, I do not even think that it is getting executed. And if it is, it is not adding the scheduleDays to the database, with their specified values. I get no error message, or anything.Is there a better method to extend, instead of OnValidate? Since, there could still be errors with the Schedule being created. Also, is there anything else in my code that is preventing it from running?
I've been using WebBrowser.DrawtoBitmap() in my asp.net page running in separate STA thread to capture web pages as an image. But I found that I'm getting blank images for few sites consistently. I'm aware that the method is not 'officially' supported but it would be nice if someone can provide me any reason or a work around for these blank images issue.

I have a GridView bound to an ObjectDataSource. Most of the columns are directly databound, however one column is not - it's value is determined in code. The value is being calculated correctly at the RowDataBound event, however when there is more than one data row in the GridView, the calculated fields for all of the rows is blank, but the top row displays the bottom row's calculated field
I am having a gridview with alternative color i have used AlternatingRowsDefaultCellStyle. however, if my grid is not fullyfilled, ie the grid view page size is 20 and i have only 10 records in that page then the alternate row color will not apply for blank rows. My question is, How can I fill the blank rows with alternate color as well.
Hope there is some solution without adding empty rows at the end of the datasoure which will create problems while sorting the grids.
I found code [URL] that allows multiple-row inserts, and tried to convert it to vb.net. I can't get the blank grid with 5 rows to show up -- for some reason the datasource won't bind.
While uploading excelsheet to datatable and bind it to gridview it will check blank data in excel sheet and when it will bind to gridview,the row in which blank present that row will be in red background color and the other row will occur in normal back color.

I am using LINQ to SQL with C#. Is there a method through which we can generate entity class files from the table schema? By dragging tables onto the graphical designer classes are generated but they are not the real class files(i mean actual files with the extension cs).
I am aware of that we can code the class files first and then create the schema manually or programmatically, but i wanted to know if the reverse is possible, may be using some third-party tools. I feel it will be very convenient to use LINQ that way.

I have an asp:Table and around the mid point of the table there is a DDL with values 2-5. What I want to do is add the selected amount of rows using AJAX right after the table row that has the DDL in it. I know how to dynamicly crate the rows, the info in the rows, and how to use AJAX to make things. Problem is I can not put the ContentTemplate tag inbetween the asp:TableRow which would mark the location I want the dynamic rows to start being added. I did some searching on here but most posts I find start with making the table from code and not the asp:Table tag

GridView: grvResultPrimary Key: FLTIDTextBox: txtRemarksThere is a button named btnAdd in the FormView named FormView2.txtRemarks is outside the form.The scenario is that if user wants to add a record with empty textbox and click btnAdd then how to restrict user to add empty row to gridview?I have tried Validation by controling txtRemarks but it is not helpful for me because in the page there is a FormView1, FormView2 and grvResult.If I am applying validation then all other updation methods of FormView1 and grvResult are disturbing.Simple is that I want to give option to user that without empty data using txtRemarks, user can enter data to grvResult.
I have two possible header rows for a DataTable that I build dynamically. Setting the value of a cell works fine. Adding the cell to a TableRow works fine. The problem comes in where I have to build a second possible header row that uses the same cell.
An example is below.
trHead1 = New TableRow trHead2 = New TableRow tcCalc = New TableCell tcCalc.Text = "Rates" trHead1.Cells.Add(tcCalc) trHead2.Cells.Add(tcCalc)
As soon as I make the second row add the cell, the cell disappears from the first row. This really doesn't make sense to me but that seems to be the way it is. If there is a work around other than duplicating the lines;
I 'm curious to know how I could hide rows in my <table> in logical cases where, for instance, I have a list of radio buttons and depending on whether the user selects "Yes", the row below it appears for them to fill in some information.
