I'm trying to add a second command field to an asp.net gridview. Essentially, I want the user to have the options to delete and update records on one page. I've gone through gui's to do this that I have found on the web but none of them work. I think that this is because of the fact that I am working with Visual Studio 2008, so the gui's don't match. Plus, my datasource isn't allowing me to add delete parameters, and update parameters. So, my present goal is to have multiple command fields in my gridview. This would also enable me to add a "duplicate record" functionality, as is needed with this program. I would also like add functionality. If possible. I've been doing all this on multiple screens but I believe I should be able to do this on one screen. Here is my gridview and datasource.

View 7 RepliesI have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
View 3 RepliesI've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
I have a gridview where I am looking to do a custom command with a template button. I am trying to get the current row that is being selected, but I cannot seem to figure out what I am doing wrong. Here is the gridview source:

I have added a Command Field in a Gridview Dynamically. And I have added the OnClick Attribute in the
RowDataBound event
[code]...
and ProceedAction() function have confirmation message. When i click the Delete button, the confirmation message is shown. But the Row Command is not fired (even if i click Ok/ cancel in the confirmation message).
I have analysised Little bit. If i have '\' or '{, }' or '*' in the javascript function, the behavior is improper (as i said above). If i remove it, it is working fine.
Since i need to ask two confirmation, i need to put '{, }' in my javascript. So how can i resolve the above issue.
I have a gridview bound to a dataset and I do not want to display the id column or the select hyperlink. How can I have a user click anywhere in a row and have the application behave as if they clicked the standard select hyperlink. the one or two approaches I have seen on blogs have not been successful for me. maybe I was missing a piece
View 4 RepliesI have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.
i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);
I have a gridview and sqldatasource in a form. My sqldatasource has select,delete and update command. The delete command is working but the update doest not work when I click the update command field.

The linbutton shows Purchase_order_no. When i clicked on a paricular purchase_order_no., it will navigate to another page with a gridview that shows details of that particular Purchase_order_no...
I have a Linkbutton on a Gridview which has got the below RowDataBound:
[Code]....
The above javascript will close the page automatiically. My intent is to close the page after the Link in the template field is clicked, but here the page closes automatically when its loaded.
I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:
[Code]....
I have a table in my Database called Creditors.
One of the columns is Paid which is type Bool.
On my aspx I have an objectdatasource and gridview. In the DAL is a method called GetCreditors which
returns all the creditors into the Gridview.
In some cases the "paid" column is ticked and in other not.
I want to run a select query that only gets the rows where PAID is not Ticked. insead
of retrieving all.
I have a gridview where I am using the update. I have converted the label into a templatefield and added a dropdownlist which is getting polulated in the Rowdatabound event. When I test the update i get an error
Cannot insert the value NULL into column 'StartTime', table 'HTC.dbo.EventDates'; column does not allow nulls. UPDATE fails.The statement has been terminated. so I am ussuming its still trying to update from the label rather than using the dropdownlist. here is my code:

I have a gridview control set up like so:

I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...
I have a GridView that is bound to a DataTable containing questions. Each question has a possible score of 1 to 9 which is handled by a Template Field with a RadioButtonList databound to another DataTable (containing the values 1 to 9). This all works fine except as an added complication, some of the questions have an extra choice in another field. So the problem is how do I bind the second Template Field to a datasource that is dependent on the question. It's like passing a parameter to the datasource of the second Template Field, the value of the parameter being the Key Field of the particular row. Is this possible and if so, how do I do it
