As GridViewRow = GridDetail.SelectedRow
Dim fName
As String = selectedRow.Cells(1).Text
Dim lName
As String = selectedRow.Cells(2).Text
Dim Iname As
String = selectedRow.Cells(3).Text
all I need is to get the values inside the table.

I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.

View 2 RepliesHow to bind a repeater with database table values as source. i have a transaction table with all user transactions. i want to show only the
last 5 transaction made by user. how to achive this. every user will have unique id. how bind the repeater table dynamicaly.
To start with - I'm using VS 2008/.NET 3.5 and working in a company-provided template that leaves me restricted to some/many settings that go beyond the body of the page itself. That said, I need to create a page that will display data from individual cells in a database table that, when lined up would look like a normal sentence. Based on certain criteria I would have certain sections of the sentences hide (ex. if it contains a key phrase or if it's empty).
I've seen a method in which Labels could be used to achieve this effect, where I would assign it the grid coordinates of the cell in a table, but I could never get it to work. I've been successfully connected to the table (LINQDataSource) but still have a blank canvas without this fundamental display technique as that will be all that's in it.
i have a form with several checkboxes....i want to insert the selected checkbox values in to a single column in the sql database..
View 4 RepliesI want to name the headers of the ListView control acording to values of the first rows of a table in the database. This I want to do because the number of columns varies for each cutstomer and also the name of the column.
View 10 RepliesI have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
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'.

how to get the values text box values to gridview..
if i enter any text in text box those values should display in gridview.
after entering of 2 or 3 records, i will click on save then all the values of grid should insert in to DAta Base.
i dont want to get the values form Database to Gridview.
how to retrive the values form Database to Gridview.
i just want to display the values which are there in Textbox...
I would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.
Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.
Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.
Below is my visual basic codes:
[Code]....
Below is my Stored Procedure code:
[Code]....
I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.
Is there a way to copy a row from one table and insert to another but at the same time insert extra values to destination table?Let's say source table Item has values:
ItemID
ItemType
ItemProducer
ItemModel
Destination table ItemHist:
ItemID
ChangeDate
ChangeReason
ChangedBy
ItemType
ItemProducer
ItemModel
I want to copy row from source table where itemid is 25, insert it into destination table and add extra values: ChangeDate, ChangeReason, ChangedBy. I tried:
INSERT INTO ItemHist (ItemID, ChangeDate, ChangeReason, ChangedBy, ItemType, ItemModel) VALUES (ItemHist.ChangeDate=GetDate(), ItemHist.ChangeReason="why not", ItemHist.ChangedBy="me")
SELECT ItemID, ItemType, ItemProducer, ItemModel FROM Item WHERE ItemId=25
but obviously it didn't work ("The name 'ChangeDate' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.").

declare @i int
set @budget=20
set @cnt= (select COUNT(*) from PostGL where AccountLink=2 )
set @i=1

i need ....totaldiff=totaldebit-totalcredit
I have a problem that can't find a way to do it, I have a gridview with this columns:
ID | AreaName | CostCenter
with the "Enable Editing" option check and what I want to do is to get the values of areaname and costcenter and assign them to a label control so I can use the values for something else, for example:
ID AreaName CostCenter
1 Multiconector 1025
2 One Conector 2065
3 Plug & Play 1445
4 Splitter 1598
5 FNI 4298
and if I hit the edit button of the row with ID 4, assign the values to the labels lblAreaName = Splitter and lblCostCenter = 1598
Before I edit them, and so on with the rows I want to edit.
I want to get the values from a cell in a gridview so can I do that without selecting a row. Its something like this I have a drop downmenu and based on the value selected in the dropdown menu I have to change the presentation of gridview without going to the database.

I need to get values of all individual cells from the row of a grid view and assign eac one fo them to seperate variables. Should i just access the control values directly from the gridview (the controls are template fields) or is it best to run an sqlq select query for each value i want to retrieve.
I'm writing a gridview in VB.NET that is bound programatically in the Page_Load function. I am binding the data in the 'If Not Page.IsPostBack Then..." structure. And as you can see, I'm using TemplateFields instead of BoundFields. And I need to access the e.OldValues in my RowUpdating function, but they come up empty.
