I have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?

Have a gridview that is populated via a DB, which is populated by another tool. That tool records all the data, including the user that submitted it.
The site also enables editing, but I want only the user that submitted the data to have the ability to edit HIS data only, even though the grid view is displaying other people's datas.
So currently the gridview has "ShowEditButton="True"
So on the far left, there is the Edit option for all lines, for all users, for any user viewing the site.
I want to do a verification where,

I've got data in a DetailsView control which shows the data and expands the rows to suit the content.
However, when I click to edit the information, the editing area changes to just a few characters wide.
How do I change the size of the editing area to match the view data state?

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
View 1 RepliesI have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.

View 11 RepliesI have a Gridview where the user can edit a row when he click on "Edit" (this is called update mode i thinck?).
When the editing is done, the user clicks on "Update" and the changes are written into the database. Additionally i set a "ChangeMarker" in the database that the data record has been changed by the user.
I identify the row in the database i want to update with the SelectedDataKey in the Gridview:

In the first line where I dim EdittedRow i got an error: "Object reference is not set to an instance object". I dont understand this error message.
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I have two tables
Employee Table : ( EmployeeID,EmployeeName,... Etc )
Bonus Table : ( BonusID,EmployeeID,BonusDate,Bonus Reason,... Etc )
I wanted to list the bonuses in a gridview, so i made a query to return list of bonus records and my data access object returns the result set as Bonus business object ( generic collections of bonus BO ). i have bind my gridview with the bonus collection.
now my problem is that collection has the property "EmployeeID" and it will be displayed but instead of showing EmployeeID, i wanted to show Employee Name in that grid. I have a gridview where i want to list the bonus records ( bonus ID, bonus date, bonus description, employee ID) ,

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

my gridview binds to a datatable and i added a template field to the columns the template field contains a link button. i bind the command argument of this link button to a field from my data table. on the row command event i allow the user to activate his product according to a condition. what i want is how to add a javascript alert if the condition doesn't match. in other words i can't call the hyperlink in the templatefield in order to add a javascript to its OnClientClick attribute.
View 8 RepliesI have a gridview based on a sqldatasource that has some colums from which two colums showing the data of two fields: field1 and field2. field1 is an ID which should not be updated and therefore it is readonly=true. The sql-query from the sqldatasource is:
SelectCommand="SELECT field1, field2 from anyView"
What I want is, that when a row is updated, then the value from field1 should be copied to field2 The update-query is:
UpdateCommand="UPDATE myTable SET field2=@field2 WHERE field1=@field1"
My idea was, that the @field2 paramter gets the value from the query string out of field1:
<UpdateParameters>
<asp:QueryStringParameter Name="field2" QueryStringField="field1" Type="Int32" />
</UpdateParameters>
But this does not work. Is there an easy way to copy the data from field1 to field2 when updating the row? In addition, is this possible, even if field2 ist not shown in the gridview (i.e. field2 is selected in the query but is not a field in the gridview but should be updated with value of field1).
I have a Gridview with a hyperlink field. The hyperlink will open a pdf file from a folder in the root of the web if there is a corresponding file. My problem is that there may or may not be a corresponding file and if there isn't a file then a browser window opens up and the contents of the folder are displayed. This folder will be maintenanced from day to day adding and removing files. coding something that will either disable the hyperlink were there is no corresponding data or just pop up a message that there is no corresponding data to view.
