Can anyone please help.. I have create multiple child hierarchical grid but i cant seem to see the fourth level and fifth level. I dont know if its the size of the child template is the problem or something else. Isn't the child template autoresized?
Here is a copy of my code, if the problem is not what i stated please tell me what i'm missing thanks!
if (list.Keys.Count > 0)
{
//Child Template
GridViewTemplate template = new GridViewTemplate();
template.AllowAddNewRow = false;
template.Columns.Add(new GridViewTextBoxColumn("ParentID"));
template.Columns.Add(new GridViewTextBoxColumn("ID"));
template.Columns.Add(new GridViewTextBoxColumn("Key"));
template.Columns.Add(new GridViewTextBoxColumn("Value"));
parentTemplate.ChildGridViewTemplates.Add(template);
//Relation
GridViewRelation relation = new GridViewRelation(parentTemplate);
relation.ChildTemplate = template;
relation.ParentColumnNames.Add("ID");
relation.ChildColumnNames.Add("ParentID");
radGridView1.Relations.Add(relation);
//Get Key and Value
foreach (string str in list.Keys)
{
GridViewTemplate newTemplate = parentTemplate.ChildGridViewTemplates[0];
newTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
childCtr = childCtr + 1;
string strCtr = parentID.ToString() + childCtr.ToString();
if (list.ValueIsList(str))
{
LogEntryPropertyList listChild = list.GetList(str);
newTemplate.Rows.Add(parentID, strCtr, str, null);
newTemplate.Columns[0].IsVisible = false;
newTemplate.Columns[1].IsVisible = false;
parseLogEntryList(listChild, newTemplate, ulong.Parse(strCtr));
}
if (list.ValueIsString(str))
{
newTemplate.Rows.Add(parentID, strCtr, str, list.GetString(str));
newTemplate.Columns[0].IsVisible = false;
newTemplate.Columns[1].IsVisible = false;
}
}
}

I checked your examples and the same problem is in there in the Hierarchy section of the gridview. When you expand all the levels sometimes you can only see half row and cant read the content. Can you do something about this? We need this in our project because where creating multilevel hierarchy that can go more than 5 levels. Thanks in advance.

Hello Paul,
You are correct. We have an issue with the child templates which prevents you from seeing their content properly in some scenarios. This issue will be addressed in one of our next releases. Unfortunately, I cannot provide you with a workaround for the time being. Please excuse us for the inconvenience.
If you have additional questions, feel free to contact me.
Best wishes,

Does anyone know if this has been addressed? -or- when it may be updated? I know a lot of changes were made to the gridView recently, but my app still exhibits this behavior. So I am hoping that maybe I missed a property or a new "trick/work around" that will allow my application to function. Thanks in advance!

Hi Alon,
Although the logic for calculating the height of the child grid views is not changed, you can easily resize them by a mouse drag-and-drop operation. Alternatively, you can set a custom height programmatically. Both approaches are documented in this help article.
You can also refer to this forum post regarding the topic of resizing a child grid view programmatically.

I just created a grid with 5 levels and can only display the first 3. When I click on the + of the fourth level, nothing happens. It's over a year since this problem was identified and I have the latest updates. Has anything been done? Under which scenarios does this happen? Maybe I can change some of the settings. In my grid, the first four levels are display only (no add, edit or delete) and the fifth one can be updated. Is this causing the problem? I'm also not displaying all the columns on each level. Otherwise, there is nothing special about it.

Hello Ruth Goldberg,
The layout calculations of hierarchical RadGridView have been improved during the last year. However, recently we discovered that there are still some issues with the layout. There are no specific circumstances under which this happens, the height of the child GridViewInfos is just not calculated property when there are four or more levels of hierarchy. We will do our best to address this issue in the first service pack of Q1 2010.

Thank you for writing us back.
It seems that we have missed a case. Could you send us your application, so that I can research the issue in detail and try to find a proper solution? You can do so in a new support ticket.
I am looking forward to your project.
