Gridview rowupdating no rows I phone sex chat

A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.

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.

In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.

NET Grid View markup and associated code lets first enumerate the important code pieces of this tutorial.

In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.

Then again we have to call that Bind Grid Data () method to bind data for the textboxes. You can leave a response, or trackback from your own site.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. The above piece of code will also do the same as label in Item Template and Textbox in the Edit Item Template.By default all the boundfields will be trasferred as Textboxes in Edit Mode.To do this we first need to obtain the reference of the current row by using its index no as shown in the first line below.By using the Grid View Row object we can find the reference of any control in the row in which user is editing the data.If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.Ok let’s move on to Code behind what we have to do when user clicks Edit, Delete, Update and Cancel When we click on Edit the On Row Editing event will be fired.
