I was trying to move the NewRow to the bottom of the RadVirtualGrid. This is also supported by its big brother RadGridView. I have now learned that this is not supported by RadVirtualGrid.
Hereby my request: Please support this!
I've created a Harmony patch (which works for me); it might help you if you decide to support it:
static class MoveNewRowToBottom
{
[HarmonyPatch(typeof(VirtualGridTableElement), "InvalidatePinnedRows")]
static class VirtualGridTableElement_InvalidatePinnedRows
{
static private bool _isInvalidating;
static private bool Prefix(VirtualGridTableElement __instance)
{
if (_isInvalidating)
return false;
_isInvalidating = true;
__instance.ViewElement.TopPinnedRows.DisposeChildren();
__instance.ViewElement.BottomPinnedRows.DisposeChildren();
var viewInfo = __instance.ViewInfo;
var rowsViewState = __instance.RowsViewState;
var topPinnedItems = rowsViewState.TopPinnedItems;
var bottomPinnedItems = rowsViewState.BottomPinnedItems;
if (viewInfo.ShowFilterRow)
if (!topPinnedItems.Contains(RadVirtualGrid.FilterRowIndex) && !bottomPinnedItems.Contains(RadVirtualGrid.FilterRowIndex))
rowsViewState.SetPinPosition(RadVirtualGrid.FilterRowIndex, PinnedRowPosition.Top);
if (viewInfo.ShowNewRow)
if (!topPinnedItems.Contains(RadVirtualGrid.NewRowIndex) && !bottomPinnedItems.Contains(RadVirtualGrid.NewRowIndex))
rowsViewState.SetPinPosition(RadVirtualGrid.NewRowIndex, PinnedRowPosition.Top);
if (viewInfo.ShowHeaderRow)
if (!topPinnedItems.Contains(RadVirtualGrid.HeaderRowIndex) && !bottomPinnedItems.Contains(RadVirtualGrid.HeaderRowIndex))
rowsViewState.SetPinPosition(RadVirtualGrid.HeaderRowIndex, PinnedRowPosition.Top);
var elementProvider = __instance.RowScroller.ElementProvider;
var topPinnedRows = __instance.ViewElement.TopPinnedRows;
foreach (int topPinnedRow in topPinnedItems.SortTopRowIndexes())
{
VirtualGridRowElement pinnedRow = (VirtualGridRowElement)elementProvider.GetElement(topPinnedRow, null);
topPinnedRows.Children.Add(pinnedRow);
pinnedRow.Attach(topPinnedRow, null);
}
var bottomPinnedRows = __instance.ViewElement.BottomPinnedRows;
foreach (int bottomPinnedRow in bottomPinnedItems.SortBottomRowIndexes())
{
VirtualGridRowElement pinnedRow = (VirtualGridRowElement)elementProvider.GetElement(bottomPinnedRow, null);
bottomPinnedRows.Children.Add(pinnedRow);
pinnedRow.Attach(bottomPinnedRow, null);
}
_isInvalidating = false;
return false;
}
}
static private IEnumerable<int> SortTopRowIndexes(this ReadOnlyCollection<int> topRowIndexes)
{
var specialRowIndex = topRowIndexes.Where(index => index < 0).ToList();
if (specialRowIndex.Contains(RadVirtualGrid.HeaderRowIndex))
yield return RadVirtualGrid.HeaderRowIndex;
if (specialRowIndex.Contains(RadVirtualGrid.NewRowIndex))
yield return RadVirtualGrid.NewRowIndex;
if (specialRowIndex.Contains(RadVirtualGrid.FilterRowIndex))
yield return RadVirtualGrid.FilterRowIndex;
foreach (var index in topRowIndexes.Where(index => index >= 0))
yield return index;
}
static private IEnumerable<int> SortBottomRowIndexes(this ReadOnlyCollection<int> bottomRowIndexes)
{
foreach (var index in bottomRowIndexes.Where(index => index >= 0))
yield return index;
var specialRowIndex = bottomRowIndexes.Where(index => index < 0).ToList();
if (specialRowIndex.Contains(RadVirtualGrid.FilterRowIndex))
yield return RadVirtualGrid.FilterRowIndex;
if (specialRowIndex.Contains(RadVirtualGrid.NewRowIndex))
yield return RadVirtualGrid.NewRowIndex;
if (specialRowIndex.Contains(RadVirtualGrid.HeaderRowIndex))
yield return RadVirtualGrid.HeaderRowIndex;
}
}
This width is 6px by default and it doesn't offer convenient API for customizing it:
Implement support for UI Automation. When the control is focused, Windows Narrator will read the AccessibleName property if set.
We could improve the existing logic by raising it indifferently.
For example:
I want to choose columns by checkboxes, something like this:
I might be missing something, but I have Hyperlinks in a column in my RadDatGridView.
I tried searching for a Support document explaining this, but didn't find any.
When the grid is exported to excel all data is coming across, but the column with hyperlink is not
a hyperlink in Excel.
Below is sample of the code used to make the "HyperLink" column in my grid.
radGridView1.DataSource = dtResults;
radGridView1.Columns.Remove("Path");
GridViewHyperlinkColumn col = new GridViewHyperlinkColumn();
radGridView1.Columns.Insert(5, col);
col.Width = 200;
col.FieldName = "Path";
col.HeaderText = "Path";
col.Name = "Path";
Coded used to do the Export....
GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
spreadExporter.ExportVisualSettings = true;
SpreadExportRenderer exportRenderer = new SpreadExportRenderer();
spreadExporter.RunExport(filename, exportRenderer);
Thanks.
