• Re: How do you display errors/messages in a grid view?

  That's pretty much what I managed to get to; in fact, I used this; which is slightly more durable. 1 Control c = (Control)sender; 2 Control m = c.FindControl( "MyMessageLabel" ); 3 while (c.Parent != null && m == null ) 4 { 5 c = c.Parent; 6 m = c.FindControl( "MyMessageLabel" ); 7 } 8 ((Label)m).Text = "Well done, change effected." ; 9 ((Label)m).Visible = true ; Of course, it should have another null check before line 8, but that's okay, I can live

• Update panel from custom control

  Web web app looks similar to a file explorer - on the left is a tree heriarchy and on the right is a content pane. At the moment I have it framed, with the tree on the left, and the content on the right. However I want to be able to produce the same effect with update panels. The trouble is, I don't know how to trigger the panel to update from the custom control on the left (and pass a parameter to it, so that it updates with the right content). My custom control is basically a jQuery file tree

• Re: How do you display errors/messages in a grid view?

  [quote user="ecbruck"] That's really up to you, but most often the error message is set to the Text property of a given Label outside of the GridView. Some will use multiple Labels with predefined messages and simply turn them off and on as needed. I myself use a custom ValidationSummary that can be written to so that all of my errors can be summarized. [/quote] I guess the question after this is; "how do I access those labels?" From the updating event I can access the gridview

• How do you display errors/messages in a grid view?

  I have an editable grid view and I am using handlers to verify inputs. What is the best way of passing errors, warnings and messages back to the user of the grid view?

• GridView update fails silently if (optional) fields are left blank

  I am using a gridview with a SqlDataSource object to view and edit records. Unfortunately I have the following symptoms: If all the columns have data in the update commits fine, if however, any one of the columns is empty, the update fails. I am using a stored procedure for updates which specifies default values (therefore values should not be compulsory) The update "appears" to have worked- as in my grid view returns to the view mode, and no exceptions are thrown. The SqlDataSourceStatusEventArgs
