Gridview not updating on edit
For demonstration I have created a database (named Database.mdf) in which we have a table named tbl_Employee.
Hi all I have a dropdown list in a gridview edit template however on updating the row the value selected in the dropdown doesn't get picked up on the update and so it updates the database with a null value here's my template code from the aspx page ok I have tried this and it works however I don't want to display a null option in the list, I would just like to display the valid options is there any other way that means I don't have to include a null value?
Now I know the trick is always to check Key Names because 99% of the time that is the culprit, but I believe that is fine.Hi, I am having a Rad Grid View with one particular Grid View Data Column having a Button and textblock as a cell template.On Click of any of this button, I want to edit the details of that particular row.When I tried to update the tracking Num, I got Item Dispached being marked as checked. This example shows how to edit and update records in a Grid View in ASP. This example is helpful in situations where an administrator needs to edit several records from the database.By default all the boundfields will be trasferred as Textboxes in Edit Mode.To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP. So am calling the method Bind Grid Data method which is overloaded . The problem is, that when I press update with a breakpoint on Sql Data Source. This prevents the grid from updating for some reason. Hi there, When you call Data Bind in Page_Load, you tell your controls to data bind. NET 2.0 Instant Results and Beginning Dreamweaver MX / MX 2004My advice would be to steer clear of the sqldatasource and use a 3-tiered approach to retrieving, displaying and collecting data.I don't know why yet, or how to bind the page..if I remove Data Bind from Page_Load, updating is successful. This means fresh data is retrieved from the database as soon as the page loads. Is Post Back) This way, Data Bind is only called when the page initially loads and leaves your edits alone on postback. Get the data from your database using a sqldatareader and store it in a custom collection by defining your own custom object.
