Rowupdating event in gridview in asp net c

Rated 3.94/5 based on 562 customer reviews

After investigation, it looks like the Selected Index Changed is not called because on the postback with update, the Drop Down List doesn't exists, therefore the event doesn't exist.

As a workaround, I can add a javascript onchange event to the Drop Down List which is called when the value changes.

The Textbox values come back as empty, which is even stranger. Below is the code for both the Grid View HTML and the C# code behind.

Code (C# On Updating Event) protected void gv Main_Row Updating(object sender, Grid View Update Event Args e) Gridview HTML Code x WHERE (Rec ID = @Rec ID) " Select Command="SELECT Rec ID, Company ID, Region ID, Country ID, Company Code, Company Name, App ID, Country Code, Country Name, Region Company ID, Region, Model Name, Translate Model, Price, Last Updated On, Last Updated By FROM dbo.

i went through for loop and if loop and did all things which were of total failure i came across this right now. The code which you provided roughly a fortnight has done wonders for me. Click 'Display the Table with data in the gridview 'clear the current content of the Table dt. Find Control("txt City"); and i assume that the txt City. Old Values and New Values both have length 0, and the Text Box approach described above gives a null reference after conversion. I've posted the ASP Code, and decided to skip the actual binding code, since it works great; checked it with the debugger.

this is the function that is called by all control when sending information to the server.

So, you could use it in the javascript onchange event.

The other solution is to drop that dynamic control creation and uses standard item and edit templates (declaratively in the aspx file) With just Build Grid() called, then the ddl is null.

Unfortunatley, I can't drop the dynamic creation, as this app is used to maintain three different systems, and being defined by an XML configuration file, means that the page can be used to maintain multiple tables.
