I have a grid view in which when i enter values and press submit button , all the values were shown on the grid . I want to edit the row and after that updated it.
I have used RowEditing function but when i click on the edit button it appears to be blank page means that row editing function not called.
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I am using ListView for the first time. I have a requirement that in a listview if I Edit a record and before clicking teh Edit button of tthis record if i click on the "Edit" button in other record, my first record should be saved and second record should open in Edit mode.
I have gridview and sqlDataSource. In edit mode, if the user checks closed checkbox closeDate parameter is set to today and appears in a label near to checkbox. So, I need to control isClosed checkbox and then if it is true closeDate=GETDATE()
[Code]....
Only CloseDate parameter need to be set in codebehind, other parameters handled in gridview.
I have two grid view controls one is temporary and another is simple grid view control.in the simple grid view control it includes the edit button on its command name edit i want to edit this grid and also to show values in the temporary grid. How it can be possible?
I have GridView with my own Edit/Update functionality.
What is the best place to put the call for the update function?
I know that placing the Update button will have the click event.
I have extra textboxes and other controls placed on the edit-mode that will have me to find them. So, what is the best place to put the call for the update function that will let me find these controls to be updated?
Is it via GridView_RowCommand and the use of CommandName ?
I have a gridview and am using the Edit - Update function to update one field in my gridview. I have the textbox appearing as I want it and am able to update the data for that cell.
The problem I have is refreshing the gridview after the update. The Update and cancel are still shown instead of the gridview refreshing back to the Edit statement after the update.
I have a page has Listview and Datapager inside UpdatePanel. When I refresh the new SQL results and bind by pressing link buton outside of the update panel, I get correct results. (get new SQLselect statment, rebind to listview, update updatepanel)
However, the SelectCommand is not bound right or some other reason, if I press datapager, I won't get no results.
I'm guessing it's caused by not passing new dynamic selectcommand since my datapager and listview works first update.

i have a grid form with 3 fields field1 & field2 & field3.
in the insert statement the field 3 gets a javascript function result that uses filed1 & 2 values.

(//// Or simply what i want is to do the same calcultions onthe fields while perfoming an update operation.. //).

In my application if I get an exception I catch it and send stackTrace through email. I also need the values of parameters passed to this function. I can get the names of function and parameters using MethodBase class of System.Reflection.
Is this even possible? I'm trying to pass the DataKeyName (Primary Key) of my master gridview to an embedded child gridview, using a select controlparameter of the SQLDataSource control.
I have a GridView with drop down boxes that are always in edit mode, and what I want to do is when the user sets a value in one of the drop downs I want to set the value in all of the drop downs BELOW that one (if they are not currently set) to the same value. However, the RowEditing and RowUpdating events never fire because techncially I'm not editing or updating the row.
Here is what I'm wanting to do, something along these lines:
[Code]....
Here is what is corrently working, but it sets the values both above and below the current row:
I'm using a code-behind function (called TestFx) in my binding expression. I'm passing a string and the function accepts a string but I still get a runtime error saying invalid args.
But if I change the method to accept an object and inspect the value, "it's a string!"
I have created a web based form which has a drop down list (DDL) that lists various company names. I want to create a box in the form which displays the contact info for that particular company which is chosen in the DDL. Also, I want this info to be in a greyed area so that user cant modify (can just copy it).
what asp tool i should use for this (I am guessing textbox wont be good enough since user can modify the info that populates in it)
How to make the selected record (area) for editing to be in the center of the screen?
I have a GridView with custom Edit functionality. I have panel, table and some controls for updating in the EditItemTemplate area. When the user selects to edit a record, I want the edited record area to be aligned in the center of the screen. What is happening now is, with the gridview having many records; the user has to navigate to find where the edit box displayed!
I have a GridView control connected to a SQL database via an sqldatasource. I want to load the contents of a row being edited into an HTML editor when the edit button is clicked. Is it possible to do this and if so how? I have found the rowediting event with which I have created a subroutine, I just don't know how to access the data in that row?
I have a dinamically gridview, populated according with the SQL sintaxe from the user, with a TextBox. I enable in the gridview an Edit button, and the rowEdit works well when fired. But my problem is Update button. How to save the record edited, in a dinamically gridview, when I can't programatically set the fields to be saved? Ie, I need to iterating with all fields in the gridview edited record and update. How to do this?
I have 3 gridviews on my page, all with the same columns. I want the user to be able to click on a button and it export all three gridviews to an Excel file, whether on 3 different worksheets or the same worksheet (preferrably the same, but either will do).
And in code behind, I insert footer rows to total by department, so if I use this
Export to Excel control it will export only 1 gridview at a time and won't export the inserted footer rows separating the departments.
I am using a grid form to diplay data... the insert form is completely a separate form. In the insert form a text box called "FormPercentageTextBox" is getting a calculated result using javavascript based on some field ( field1,field2) values (val1, val2).
the problem i have is: when i edit the form and i want to update any value..i want the new calculation result showing on the edited "FormPercentageTextBox" field. I need to have this calculation reflected/
