Gridview rowupdating event handling
To finish up then one has to set the Sql Data Source Update Parameters to the desired values.
The syntax for doing so is: Protected Sub GVSupport Info_Row Updating(sender As Object, e As System.
However I found that I can subscribe to a tableadapters.adapter.rowupdated event directly from within code using the tableadpater as below entry?
If you're creating the adapter explicitly in your code, just add the call yourself.
I found that simple data binding of my Drop Down List in my Grid View to my Sql Data Source was not going to be enough.
I would need to set values passed to the Sql Data Source control on the update event, and as part of this I would need to reference the controls contained in the row being updated.
Sql Data Adapter cust Adapter = new Sql Data Adapter( "SELECT Customer ID, Company Name FROM Customers", connection); // Add handlers. Row Updating = new Sql Row Updating Event Handler(On Row Updating); cust Adapter.
v=14625 if you look at this video you can see, that you just double click on something in the dataset designer and the event gets generated and wired up for you...this works only for VB programmers :)) sux // Assumes that connection is a valid Sql Connection object. Row Updating -= new Sql Row Updating Event Handler(On Row Updating); cust Adapter.
What I've done in the code behind is skip the custom portion of the event handling if the text length of the selected item in the drop down list is Hi compguy2100 , If you connect your Grid View control to one Sql Data Source control at inline code , and if you have setup Sql Data Source's updatecommand correctly, you need not to write any code , and it will automaticlly do updating.
Once the data-source changes, the defined event handlers may not work the same, because the dynamic data-source is taking a parameter...
However, the Row Editing event handler doesn't exist in the code-behind. Data Bind(); This is the partial stack trace - after the postback: [Http Exception (0x80004005): The Grid View 'Grid View1' fired event Row Editing which wasn't handled.] System.
How do I re-create the row editing & updating event handlers in the code behind - to handle these events when they are fired after the new data source is dynamically created and bound to the control?
