Hi there.
I generate a GridView from a DataSet that contains two related tables. The relation between the two is intepreted by
GridView.AutoGenerateHierarchy = true;
All of this works like a charm. The only issue is that I don´t know how to make the hierarchical child stretch columns to full width. Although the Grid itself stretches to full width, the child relation does not inherit this and the colums are too narrow.
Put simple - How to stretch child colums to the full width? Everything is generated programmatically from DataSets.
Please also the screenshot in the thread below...
Thanks!

Hi!
I'm writing an app that uses a RadGridView for massive data input. Some of the values are chosen from combo box columns.
I've tried using a cast to (RadComboBoxItem) of the default editor of the columns to set the DropDownSizingMode, but to no avail...
This would be great for me as the user sometimes can not see the fullness of the descriptions in the dropdown...
Is this possible to be achieved?
Thanks!!

I have following suggestions regarding multicolumn combo. I'm sure you're already in process of implementing some of them.
- auto-complete functionality is vital for this control
- when user selects value (or writes down value, which is in the list), when dropdown is opened, displayed list (grid) should have row with that value selected. This behavior is in RadComboBox and it's very important in multi column combo too.
- there is BestFitColumns() function which adjusts width of columns but something that would adjust dropdown width according to width of columns is lacking and would help.
- there is one annoying thing - when you click on dropdown button of combo (that arrow which displays dropdown) when you are in process of validation of some control (you didn't validate control in Validating event handler by setting e.Cancel = true), multicolumn combo dropdown is still displayed. I'll submit this as a bug too, because it is causing me problems and is not expected behavior (nor standard .NET combobox control behaves this way).
I hope my input will help something and I'm looking forward to seeing this new control evolve.
Best regards,
Daniel

I construct the list of 3 my objects and attach it to the GridView. As a result all 3 lines shows the first item: "aa". DataBound of all 3 lines is OK but display does not work OK. Here is my code below:
eeList =
new List<MedCheckEntry>();
MedCheckEntry i1 = new MedCheckEntry();
i1.ReferenceNo =
"aa";
eeList.Add(i1);
MedCheckEntry i2 = new MedCheckEntry();
i2.ReferenceNo =
"bbb";
eeList.Add(i2);
MedCheckEntry i3 = new MedCheckEntry();
i3.ReferenceNo =
"ccc";
eeList.Add(i3);
gridView.MasterGridViewTemplate.DataSource = eeList;

Hi,
Christian
I would like to look in a complex treeview for a node with a certain name. How can I go through all nodes independently of the level?
For a reference I would be grateful.

Hi,
I'm using the default context menu for the RadGrid in our application. It has all teh features the customer needs but there are 2 little issues:
- The menu item "edit" still appears in the default menu even when Editing is disabled. Shouldn't that be removed automatically?
- The only item(s) I want to remove from the context menu are copy and paste. The user doesn't need to do that and it produces an error when he copies a text or a number into a DateField. Sure I can validate that in the code but I would rather remove the two items.
Is ist possible to remove the items and keep the default menu or do I have to create a custom only because of that?
Thanks

I posted this last week and it seems it dissappeared for some reason.
So I have a GridView for Winforms control on a form that refreshes the dataset every 3 minutes. Randomly during the day my users are reporting that the entire GridView control turns white and there is a red X in the control. This is the entire GridView control's canvas. Very wierd. This is the error that the user's receive:
(There is a checkbox column in the Master template, this is not a hierarchical dataset. It is flat.)

Is it possible to create the x-axis labels from a date column in my dataset? I have a date set where I want to return a series of dates, and some associated values, i.e.a structure such as;
Selecteddate (date)
Somevalue1 (int)
Somevalue2 (int)
What I'd like to show is the series of dates along the x-axis, and my values plotted above those. Although I can sort them, I won't know how many value sets (rows) I will have in advance, or if the dates are evenly spaced (i.e. there might be gaps in dates).
Is this possible? Thanks in advance for any assistance.
