Forms Data Controls :: Obtaining Specific Data From A GridView?
Jan 10, 2011
so I am new to ASP and I am confused here about how to obtain specific data from a specific cell.so, i have a gridview that i fill from a SQL source, this works fine. what i have been task to do is add an editable text box and a comments portion to the site. these controls are to be inside the gridview. my dilema is getting the primary key of the row i am inside of.
Example when i click in the text box i created and i change the text the "ontextchanged" event fires; however, i am having difficultly at that point getting the primary key from column [0] of that specific row. i need this so that i can update the database.here is some of my code

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 have a gridview which I have databinded via the quick config facility, but I need to databind one column to a completely different sql table data field - how do I do this?
If I go into Gridview tasks and select the column and edit the data binding parameter but what is the format for a table outside the source definition for the the rest of the gridview?
I have a gridview with a column of text boxes bound to a value from a database. I should be able to edit the values in each of the text boxes and just print those new values(dont have to update into the database). But my method returns only the old values, not the new values entered into the text boxes.
Here's the background: I have a GridView with suggested meetings. A logged in member can view the suggested meetings and click button "Show" to view all suggested occasions for every meeting. What I want to do now is to hide button "Show" for a logged in member if she/he owns the meeting (i.e. is the one who suggested it = Session["memberID"]).
My problem is this: All buttons "Show" are visible. I want to hide button "Show" in those cases where Session["memberID"] is identical to dr[0]. 'ID' in the SQL statement is the ID of the meeting in the database and meetingID are the ID's of the meetings shown in 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.
My question is how to freeze specifi columns of Gridview control ? Freeze means...for example say if we are freezing the first column of grid then on scrolling a horizontal scroll bar of the grid will scroll all columns other than the first column. That means the first column will be visible always without any movement. But the first column should move if we use the vertical scroll bar.
I have a situation where i need to update my Dropdownlist templatefield inside a GridView....but only for a specific cell. I have seen codes like this to loop through the whole GridView and update every rows in a specific column, but how do i do it if i only want to update one specific cell ? (If i know the index information of the cell, for example, I know i want to update the dropdownlist on Column 3 and Row 2)
I want to created a messaging system and to display the messages. I want to use a gridview. My problem is how can I display the new messages in BOLD rows and the readed messages in normal text.
i have a data driven web application, in my database i have this datetime column,
and in my web application i have this gridview, but the only data that i need to display are the records with todays date until the past 6 days from today, so its like 7 days all in all.
I want to display a GridView with 3 Columns: a Name, a Score, and a sort-of-ProgressBar reflecting the score. So far, I haven't been able to display the 'ProgressBar' correctly.
I placed a asp:Label inside a asp:Label [URL]. Visually, this looks nice, but the 'ProgessBar' is rigth now 50% for every row. For every row, the width of the lblProgressBar has to be the value of Score, but I can't get this to work.
Havin quite a bit of trouble with this one. I have a bunch of days that I worked in my database...mostly monday-friday and some saturdays. What I want the gridview to do is add an empty line between each sunday and monday so that it seperates out my work weeks and makes it easier to read in the gridview. I got some help here a few days ago on how to clone the db etc and I have all that working properly but I can't seem to wrap my head around how to do add these empty lines in the proper spots. Here is my code so far:
[Code]....
What ends up happening is since I "seed" a variable with a specific date, the empty space inserts start getting off by a few days after awhile. I know why this happens but I'm not sure how to fix it.
I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.
I have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.
Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.
I have Two fileds the names are QtyRec and QtyReq in my table when These two are identical(10=10) then corresponding recrod should not listed in Gridview. Can any one provide solution
Gridview Code is Public Sub retriveDataToDataGrid() Try Dim connectionString As String = "Database=pjt;" & "Data Source=localhost;" & "User Id=root;Password=prasad123" Dim query As String = "Select WONumber,paertno,mfgpart,manufacturer,QtyRec,QtyReq,QtyShort,Duedate,Notes from ilist order by WOnumber" Dim connection As New MySqlConnection(connectionString) Dim da As New MySqlDataAdapter(query, connection) Dim ds As New DataSet() If da.Fill(ds) Then GVIL.DataSource = ds.Tables(0) GVIL.DataBind() End If connection.Close() Catch ex As Exception Console.WriteLine(ex.Message) End Try End Sub
I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10.
I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to).
I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.
i have gridview and im displaying the employement history of employee.and im providing a hyperlink in empid to open employee page with update mode ..so that user can update the record.i have an issue here.only if the employeeresigned = "N" empid should be hyperlink, if its "Y" it should not be a hyperlink.
