How do you determine the selected row (active row)?

I appreciate the responses that I got on this problem.

Unfortuneatly, I am a total beginner to this type of programming. I needed a step-by-step example. I had no luck at all finding one.

I was able to finally get an answer to this through support. Having said all that, I am going to post the steps I took in C# on an ASP.NET page, below.

1. Start new Visual C# - ASP.NET project in Visual Studio 2005

2. Add an UltraWebGrid control to “Design page” in Visual Studio.

3. Additional References MUST be added in order for UltraWebGrid to work. As there is still a bug in the Infragistics controls.

While in Visual Studio, display the “Solution explorer” and add references as follows.

a. right-click on “References”

b. select “Add References”

c. click on the “.Net” tab

d. scroll down the list of References until you see Infragistics

e. select and add the following additional references for an UltraWebGrid control

1. Infragistics2.Web.v8.1

2. Infragistics2.WebUI.Misc.v8.1

3. Infragistics2.WebUI.Shared.v8.1

(the Infragistics2.WebUI.UltraWebGrid.v8.1 “should” already be there, if you have placed a grid on the Design page)

4. Add a listbox control to the “Design page” (to display selected data)

5. Add a label control to display any messages.

6. Now some Events MUST be added for the UltraWebGrid. These MUST be added through “Properties à Events” or they WILL NOT WORK.

a. click on UltraWebGrid1, on the “Design page”.

b. right-click while on UltraWebGrid1. Choose “properties”

c. While in the properties menu in Visual Studio 2005, click

on the “Events” icon, identified by a lightening bolt.

d. scroll down the list of events until you locate “InitializeLayout”.

e. Now in the blank next to IntializeLayout, type

“UltraWebGrid1_IntializeLayout”, then <enter>. This will PROPERLY add a

section for this Event to the C# code.

f. Next return to the list of events for the UltraWebGrid and locate “IntializeDataSource”.

g. Now in the blank next to InitializeDataSource type

“UltraWebgrid1_IntializeDataSource” then <enter>. This will PROPERLY add

a section to the C# code for this Event.

h. Return one more time to the list of Events for the UltraWebGrid and locate

“DblClick”.

i. In the blank next to DblClick, type

“UltraWebGrid1_DblClick” then <enter>. This will PROPERLY add a section for this Event to the C# code.

7. Now there is one section which must be typed in; So, just type in the following,

in its entirety, to the C# code.

protected override void OnInit(EventArgs e) { base.OnInit(e);UltraWebGrid1.InitializeDataSource += new Infragistics.WebUI.UltraWebGrid.InitializeDataSourceEventHandler(UltraWebGrid1_InitializeDataSource); } 8. Next there is Code, which must be added to the various sections for this example to work: a. Add the following code to the “UltraWebGrid1_InitializeLayout” section of the C# code. (obviously it wraps in this doc) UltraWebGrid1.DisplayLayout.RowSelectorsDefault = Infragistics.WebUI.UltraWebGrid.RowSelectors.Yes; UltraWebGrid1.DisplayLayout.CellClickActionDefault = Infragistics.WebUI.UltraWebGrid.CellClickAction.CellSelect; UltraWebGrid1.DisplayLayout.SelectTypeCellDefault = Infragistics.WebUI.UltraWebGrid.SelectType.Extended; UltraWebGrid1.DisplayLayout.SelectTypeRowDefault = Infragistics.WebUI.UltraWebGrid.SelectType.Extended; (Note: I believe these selections could be made within the designer, at design time, as an alternative).

b. Add the following code to the “UltraWebGrid1_InitializeDataSource” section of the

C# code.

DataTable dt = new DataTable(); dt.Columns.Add("Name"); dt.Columns.Add("Country"); dt.Columns.Add("Age"); dt.Rows.Add(new object[ { "Sam", "USA", 23 }); dt.Rows.Add(new object[ { "Marry", "Australia", 26 }); dt.Rows.Add(new object[ { "Sachin", "India", 32 }); dt.Rows.Add(new object[ { "Peter", "UK", 45 }); dt.Rows.Add(new object[ { "Cathy", "Australia", 12 }); dt.Rows.Add(new object[ { "Drew", "USA", 23 }); UltraWebGrid1.DataSource = dt; (Note: This obviously just adds some Test data) 8. Continued c. Add the following code to the “UltraWebGrid1_DblClick” section of the C# code. try { string cellVal = e.Cell.Value.ToString(); int rowNumber = e.Cell.Row.Index; Boolean chkSelect = e.Cell.Row.Selected; //Response.Write("Clicked Cell Value is " + cellVal); //Response.Write("Cell is in the Row Number " + rowNumber); //Response.Write("Is current Row is Selected " + chkSelect); ListBox1.Items.Add("Clicked cell is: " + cellVal); ListBox1.Items.Add("The row is: " + rowNumber); ListBox1.Items.Add("Is current row selected? " + chkSelect); } catch { Label1.Text = "You must click within a cell for this to work."; } (Note: The “try/catch” routine was added to handle the case where the user, DID NOT, click in a cell, but clicked on some other part of the grid.)
