Hello,

I have a grid with columns grouping, being created dynamically:

public static GridColumn AddColumn(this RadGrid grid, string column, int width, string headerText = null, string sortExpr = null, string colGroupName = null)
{
if (string.IsNullOrEmpty(headerText))
headerText = column;


var boundColumn = new GridBoundColumn();
grid.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = column;
boundColumn.HeaderText = headerText;
boundColumn.UniqueName = column;
if (colGroupName != null)
{
boundColumn.ColumnGroupName = colGroupName;
boundColumn.AllowSorting = false;
}
else
{
if (string.IsNullOrEmpty(sortExpr))
sortExpr = column;
boundColumn.AllowSorting = false;
boundColumn.SortExpression = sortExpr;
}


return boundColumn;
}


public static GridColumnGroup AddColumnGroup(this RadGrid grid, string name, int width, string headerText, string parent = null)
{
var colGroup = new GridColumnGroup();
grid.MasterTableView.ColumnGroups.Add(colGroup);
colGroup.Name = name;
colGroup.HeaderText = headerText;
if (parent != null)
colGroup.ParentGroupName = parent;
return colGroup;
}
and in ascx.cs:
foreach (var indicator in ListIndicatori)
{
if (....)
{
List.AddColumn("Field_" + indicator.Id, 100, indicator.Denumire + "(" + indicator.UnitateMasura + ")");
DataTableSource.Columns.Add("Field_" + indicator.Id);
}
else
{
var groupName = "Group" + indicator.Id;
List.AddColumnGroup(groupName, 120, indicator.Denumire + "(" + indicator.UnitateMasura + ")");
List.AddColumn("Field_" + indicator.Id + "_LD", 40, "LD", colGroupName: groupName);
List.AddColumn("Field_" + indicator.Id + "_LQ", 40, "LQ", colGroupName: groupName);
List.AddColumn("Field_" + indicator.Id + "_VF", 40, "VF", colGroupName: groupName);


DataTableSource.Columns.Add("Field_" + indicator.Id + "_LD");
DataTableSource.Columns.Add("Field_" + indicator.Id + "_LQ");
DataTableSource.Columns.Add("Field_" + indicator.Id + "_VF");
}
}

where List is RadGrid declared in ascx file
I receive the error:
Invalid column group configuration! Column "Field_10_LQ" cannot be after column "Field_5"
The columns are not always the same (i.e Column "Field_53_LQ" cannot be after column "Field_7") and does not appears all the time, but I was not able to discover why and when (in which cases) it appears.
Any help will be appreciated!

Thanks,
Antonio

please check below steps:
1. we have removed edit/delete controls for some rows in ItemDatabouind event of the grid at the time of grid load.
2. when we click on a add record button on Grid.

3. popup window shows.

4. that popup contains a dropdown box which postback to server.

5. These removed controls still appearing in background when the pop-up comes up on front

Hi ,

I have a grid panel with  form template editor. In which i kept two cascading combo boxes and used ajaxpanel for avoiding  postback . The problem here is that i need a client side row add function in grid too ..... where as Ajax panel inside form doesn't allow automatic rowinsert or update. Hence i cant add the row to grid using POPUP form editor..


Any suggestions to overcome this ....?

Could someone help me with a CSS question for the RadMenu?

I have RadMenu with several root items.  The menu is rendered horizontally.  When you hover over one of the root items so the sub menu items are displayed, the left edge of the slider panel that contains these items starts directly beneath the root item.

I would like to change that so when you hover over a root item, the slider panel that drops down always is the same width, and the left edge of it is always in the same position, while the height auto-adjusts based on content.

I am currently using a custom skin to style my menu.  Can someone tell me what classes I need to modify, and what properties I need in order to achieve this?  Below is a link to a drawing that illustrates the current behavior, and the behavior that I want.

Thank you for your time,

Hi,

I am thinking to have editable RAD grid in one of upcoming application -  All fields in all rows of RAD Grid has Text boxes/dropdown. There is no Edit button in individual rows as all fields in all rowshave has text box in them.

Is it possible to have filter in Rad grid when all fields in al lrows have text boxes/dropdowns in them ?

If yes then can you please send me demo for this ? 

Please note that editable RAD Grid in following link (Demo at the bottom of this link) is different then what I am talking here.

Does that mean I have to reinstall radcontrol AJAX in order for it to work? Could I do a repair on the rad controls? What is the recommended solution to my situation? Anyone have any experience with this?

Hi,

I am facing an issue on undocking sliding pane as left side bar. The right side having a menu panel. On hovering sliding pane does not cover (overlapp) the menu panel. Rest of the pane covers the right hand side but only the menu panel. 

This is happening while we are upgrading the telerik controls from 2008 version to 2012 version. All the issues of have been resolved but this.

The z-index of the menu penal is getting applied though new telerik DLL and the value is 7000, while the sliding pane is having 2000 z-index. Again getting applied through new telerik DLL. We tried to override the z-index but it doesn't get overridden. Any help is much appreciated.
