DataSource Controls :: Update Table Where Column Name Is Selected Dynamically C# / VB.NET
Mar 10, 2010
I want to Update Column of a Table where ColumnName will be DropDown.SelectedValue. Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DropDown. In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue' So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue' how can I resolve this ?...

I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
[Code]....
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

I have a gridview with an edit command button. When I press the edit button, it makes all the columns of the selected row editable. But I want it to make only few columns of the selected row to be editable...how can I do that?

I'm sure this has been answered many times already, but I still can't seem to find exactly how to search for this issue, so apologies in advance.
Anyway, I have a VB script for entering a row of data into a table by a web user. When this row of data is entered, I wish to take some of the values from the columns of the "primary" table, and have that data automatically create a new row of data in a "secondary" table. I think I'm part of the way there, here is my script:
[code]...
"ProductsByMfr" is the "primary" table - the table that the user adds data into when the button click event is fired.
"DealerPricing" is a "secondary" table that I wish to have some of the data from the newly-entered row in ProductsByMfr copied into. Am I even close here?

I have an asp:Table. Its with is 100%. This table has only one row but 6 columns. The width of first 5 column is fixed at 150px. The last one does not have its Width specified and so it takes up the rest. The whole row has a background. If any of the first 5 column is clicked, the background of that cell is changed to white.In my development computer, the last column has about 250px. Yet in user computer, as the monitor has a smaller resolution, the last column has only 30px or so. User complains it is ugly and wish to merge the last column with the previous one. How to do so?

I know there is a way to get all the column name from a table, but that is not what I want
I want to get only a few column name from the table, is there a way to do this?
Let say, table A has three columns that is A1, A2 and A3, I only want A1 and A2 column names, again, can this be done?
BY the way, I am using SQL Server 2005 with asp.net application.

I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

However has anyone ever seen a situation where, when you try to access the value of a column in a DataRow, you get the error "Column... does not belong to table.." when, in fact, it does?
The column name in question is called "ByWeight". I am wondering if either that, or maybe one of my other column names, is a reserved keyword and that's causing/masking this error.
If I look in the locals window and expand the DataRow, one of my columns is DBNull - by that I don't mean that the column value is DBNull, I mean the actual column itself is DBNull so it doesn't expand. I think there's a clue there.

I am able to store the current time of day in a column defined as time with the C# code as:notestable.NoteTime = DateTime.Now.TimeOfDay;The hour, minutes, seconds, and even millionth of a second is stored. But now, I need to retrieve the time and convert it into a string. I tried to use DateTime statements to accomplish this as with:
DateTime nt = notestable.NoteTime;
String FirstT = nt.Hour.ToString() + ":" + nt.Minute.ToString().PadLeft(2, '0');
Regarding the 'nt' variable, I got an error message that said: Cannot implicitly convert type 'System.TimeSpan?' to 'System.DateTime'.Regarding the 'Hour' designation, I changed the definition of 'nt' to 'var' and got an error message that said: System.Nullible<System.TimeSpan>' does not contain a definition for 'Hour' and no extension method could be found.So, how do I access the time from a table and convert it into a string for display in a TextBox?
