Can anyone write me a code where I can create a hierarchical grid programmatically by adding each row separately? I know data binding is a nice cute feature but our software design doesn't permit us using the binding directly. So I need to add data one by one in the grid, that too in hierarchical fashion.
The concept of bands is kinda confusing.
Can anyone please just write a small like of code where I create a grid, add couple of columns and a couple of rows to it. And for each row I need to two columns and 1 row each.
Thanks. I just need an idea of the thing.
You can create a DataSet with related tables, then fill it with your data. Then set your grid's DataSource to the DataSet and DataBind it. Everything will then fall into place.
Think of bands as related tables. If you are doing an invoicing system, you might have your customer list in band 0, your order list in band 1, and your order detail list in band 2. Once you bind such a dataset to a grid, the orders will be displayed under their respective customer, etc.
I posted an example here: http://forums.infragistics.com/forums/p/3298/17902.aspx#17902
Hmm. Thanx a lot. I find no issues with the above apart from the extra over head of creating a data set row by row and then binding it rather than simply adding the rows directly.
Though through trail and error I have been able to create it. Following is the code for that (firstEverGrid is a grid already declared at design time)
UltraGridBand firstBand = new UltraGridBand(true);
firstBand.Columns.Add("column2", "doosra column");
secondBand.Columns.Add("column3", "teesra column");
firstEverGrid.Bands.Add(firstBand);
UltraGridCell cell3 = new UltraGridCell("hello baby3");
UltraGridCell cell5 = new UltraGridCell("hello baby5");
UltraGridCell cell7 = new UltraGridCell("hello baby7");
Row1.Cells.Add(cell1);
Row1.Cells.Add(cell2);
Row2.Cells.Add(cell3);
Row2.Cells.Add(cell4);
Row3.Cells.Add(cell5);
Row3.Cells.Add(cell6);
Row4.Cells.Add(cell7);
Row4.Cells.Add(cell8);
Row1.Rows.Add(Row3);
Row2.Rows.Add(Row4);
firstEverGrid.Rows.Add(Row1);
firstEverGrid.Rows.Add(Row2);

This create twos rows each containing one row inside.
Now can anyone tell me how to add another column in each row containing a simple checkbox ?
Thanx
I am struggling to fire Any event from my grid. None of the events are working. Is it because I am creating the grid without binding any data to it? What could be the possible reasons?
neebz said:None of the events are working. Is it because I am creating the grid without binding any data to it?
I would expect so. Most of the events I use are part of the basic binding sequence.
What events do you expect to fire without any binding?
(And, out of curiosity, what data do you expect you grid to display without any binding? Are you creating rows at design time?)
Hello everyone,
I got around creating the Hierarchical Grid in 2 levels (level1 and level2), but how do you bind to a grid with N-Level (Level3....and so on). Please advise!
Thanks
You could save youself (and us) a bit if time if you read the entire thread before you post a question that has already been answered.
*grin*
See my post, above, that provides a link to an example. If that turns out not to be what you're looking for, then explain why it doesn't work for you.
Good luck.
anup84,
I don't myself know of a certain way to accomplish this result using our ASP.NET controls.
As a thought, you might be able to handle this using our new WebDataTree control, using a table row in the template of each node. Doing so is beyond my own personal knowledge; if you want to investigate this and find you need assistance, I suggest you post in the WebDataTree forum.
Hi MacDonald
Thank you for ur support....can we have any other control thru wich i achive this functionality.
If I'm correctly reading the code where you're creating your DataRelation objects, you have three tables: Table, Table1, and Table2. The relations you're creating mean that Table1 is a child of Table, and Table2 is also a child of Table.
WebGrid isn't capable of showing multiple sets of child tables in this fashion. You can only have one child band (roughly analagous to a single DataTable) for any one parent band.
Hi ,
I m also suffering from same problem ....can you help me. I have code snippest which is bind DataSet .
DataSet dsSearch = new DataSet();
{
new DataColumn[ { dsSearch.Tables["Table1"].Columns[0], dsSearch.Tables["Table1"].Columns[2] }, false);
new DataColumn[ { dsSearch.Tables["Table2"].Columns[7] }, false);
}
this.UG1.DataSource = dsSearch;
Problem is ....It is not display third level data. Its only display 2 level data.
I want to display
1.Comapnay
2.Contact Name 3.Matter Name
2.Contact Name
3.Matter Name
Is it possible with Hierarchical grid.
