Gridview rowupdating dataset
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.
I'm displaying xml file data in grid View via a dataset object.
I'm trying to update the xml file in the Row Updating event as follows - protected void gv Main_Row Updating(object sender, Grid View Update Event Args e) My dataset "ds" is null.
We can achieve the same functionality using Datakeys. This works fine, as long as we just "view" the data. Well, you'll just have to go through the controls collection of each cell to get a reference to the controls placed inside it. when you don't use the data source controls those collections aren't filled...that's thw way it is...unfortunatelly, that is... I suppose it would be possible to extend the Grid View control and write methods that fill the collections manually... Maybe it will be something they add before the release date... However, a recent project I worked on required a few other extensions of the Grid View control (multi-row editing, expanding rows, etc.) so while I was writing my extension I hacked together some code to extract values from a row; it's not very pretty, but it does the job in most cases.When we do an update and catch the event: void Grid View1_Row Updating(object sender, Grid View Update Event Args e) we thought we could get the values from the New Values collection of the Grid View Update Event Args e. (When you use a data source, the collection is filled with the new data). So all I want to do is this simple thing: ---- Hi, I have now the same problem. And I want to update my dataset whenever the user wants to change the values shown in the gridview. for instance, if you've got a textbox on the 1st column, then you'll have to do something like this to get its text; ((Text Biox)grid. For Bound Fields I just grabbed the Data Field property and used that as the key in the returned dictionary, but for Template Fields I didn't have that option so I just used the Sort Expression property (which means when implementing the grid, you'll have to specify the Sort Expression for your Template Fields even if sorting isn't enabled; if you don't it just creates a key called "Key X", where 'X' is the column number).
