IDragSource bug over a hidden (display:none) table row with IE browser

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :ASP.Net
I'm currently trying to create an Extender to move Gridview row order. Some of they are hidden by setting their property display to 'none'.Because the gridview act like a treeview with node that can be expanded or collapsed.From there all is well working, except with Internet explorer !Here is the problem :    When hiding a row, the drag operation works properly until the mouse reach a row having one or more preceding row hiddens.I create a some code to reproduce the bug.    1 - Open the sample in Internet Explorer and try dragging rows. You will then notice that all is well working.    2 - Now, click on the button "Toggle rows display" and retry dragging row 1 over the row 10. You will notice that when the mouse reach the row 5,          the drag operation stuck on the header of the table.    Now open the sample in FireFox, Google Chrome, Safari and repeat the same operation. You will notice that all is well working.ASPX Page :<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test3.aspx.cs" Inherits="Test3" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml&

if NULL in database table - display empty string?


I have a table in an Sql Server Database from which I want to fetch data to a form. 

[Headline] [varchar](max) NULL,
[Text] [varchar](max) NULL,

[ID] [int] IDENTITY(1,1) NOT NULL,

[Headline] [varchar](max) NULL,

[Text] [varchar](max) NULL,

I want to check both Headline and Text to see if they are null, and if so display an empty string each for them. I've looked at some tutorials but don't yet understand really how to use it. DBNull? DataRow.IsNull? Something else? Can I check both Headline and Text at the same time or do I need do check them separately?

display / insert values by comparing 2 columns of a table



i have a table which has the following columns 

A_ID, A_Value,A_Date,B_ID,B_Value_B_Date


i have another table as follows

A_ID,B_ID,A_Value,B_Value, Date


this is to be done 

* if A_date and B date are equal, one record shoould be entered to the TABLE 02. the values should be A_ID,B_ID,A_Value_B_Value and A_Date (since the date is equal, no problem; even can insert B_Date instead of A_Date)

* if A_Date and B_Date are different, then the following should happen

insert one record to TABLE02 as A_ID,B_ID, A_Value, 0 , A_Date

insert another record to TABLE02 as A_ID,B_ID, 0 , B_Value, B_Date


(As you can see, when the date differs we enter the single record of Table 01 into 2 recoerds in table 02. the Value column and Date column are related in such a way that when A's date is entered, the value for B should be 0 and vise versa..)


i tried having a UDF but in halfway remembered that we cannot include INSERTS in UDFs..

can anyone please explain me how can i solve this problem ??

Browser display incorrectly


I have a DetailsView control with width set to 540px and it displays fine in Firefox, Google Crhome, Opera, and Safari but NOT in Internet Explorer version 8? The problem is, 540px is too wide for IE to display on the space that's available. However, in other browser, it's looking fine. Since 540px is two wide for IE, if I dropped to 530px, then it works in IE. Why is IE taking 10 extra pixels to display a DetailsView control? How do I fix this?
