Making ASP .NET Gridview a little less painful
Isn’t it pain in the neck when you have to write the following for every input control whose value you want to extract from a Gridview:
public static void myGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) { string firstname = ((TextBox)myGridview.Rows[e.RowIndex]. FindControl("txtFirstname")).Text; string lastname = ((TextBox)myGridview.Rows[e.RowIndex]. FindControl("txtLastname")).Text; //....and so on.. }
Well, you can make it a little easier by implementing the following method either in a class that extends GridView or by writing a extension method. In this example, I’ve written it as an extension method.
public static T FindControl<T>(this GridView gridView, string cntrlName, int rowIndex) where T : Control { return (T)(gridView.Rows[rowIndex].FindControl(cntrlName)); }
Now the code inside my page is little cleaner and easier to write:
public static void myGridView_RowUpdating(object sender, GridViewUpdateEventArgs e) { string firstname = gridView.FindControl<TextBox>("txtFirstname", e.RowIndex).Text; string lastname = gridView.FindControl<TextBox>("txtLastname", e.RowIndex).Text; //....and so on.. }
I admit it’s not something huge but it definitely is a big help when you have to type in that statement for every single control in your Gridview!
I hope that helps some!
