ListView to GridView: It is dragged, deleted, but not in the grid.

GridView to ListView: error image

Hello,

I created a CustomSummaryItem and it work correctly when I add it to summary row with code, but if I save GridView layout and load it the custom summary wont function 

 

this is my CustomSummaryItem: 

public class CustomSummaryItem : GridViewSummaryItem
    {
        public CustomSummaryItem(string name,string sourceColumn)
            : base(name, "{0}",GridAggregateFunction.Sum)
        {
            SourceColumn = sourceColumn;
        }
        public string SourceColumn { get; set; }
        public override object Evaluate(IHierarchicalRow row)
        {
           
            var sum = row.ChildRows.Sum(childRow => (childRow.Cells[this.SourceColumn]?.Value).ToDouble());
            var time = TimeSpan.FromMilliseconds(sum).ToString();
            return time;
        }
    }

 

I would like the ability to either shrink the to fit the number of rows it has (thereby showing the background color below it) or to control the color of the dead space separately from the background color or alternating row color.

Could I change the background color of the  itself and then set each row's  individually perhaps to achieve this?

 

I just can't seem to get my PDF to load. I amcreating a RadFixedDocument.

If I export it to a file, and load it to the viewer, it works just fine:

 

Seems like this should work, what am I missing??

Hello,

After having Designer issues (i hacked the designer)  i removed my UserControl who was the problem; i created a new one wich is the exact (mostly) same UserControl.  But when i  want to create a new RadGridView i'm getting this error:

Unable to create component 'RadGridView'. 

'System.Runtime.InteropServices.COMException (0x8004D45); A reference of 'Telerik.WinControls.GridView already existe in the project.

I am using Visual Studio 2013. All my references are present. I tried to create a new Project Telerik ; i'm able to use a RadgridView in the new one.

GridView to ListView: error image

Dear, I need to load 03 listview simultaneously and these same handle many records in the iconview, what would be the best way to load and streamline this task by saving the path of the image and then assigning it by using the itemdatabound property or saving the image in arraybyte and then assigning it in the customvisualitem creation.

Thank you for your attention.

Hi,

I found the was to left-align the name of the column using the following code :

        private void radGrid_ColumnChooserItemElementCreating(object sender, ColumnChooserItemElementCreatingEventArgs e)
        {
            e.ItemElement.TextAlignment = ContentAlignment.MiddleLeft;
        }

 

But I did found how to set the height of the elements in the list of columns (see screenshot attached).

Is there any way to do it ?

 

Thank you.

 

 

Hi. I am trying to remove rows and I get "formatException".

I've try to remove the rows like that:

grid.GridElement.BeginUpdate();

foreach (GridViewDataRowInfo row in grid.Rows)
{
      if (row.Cells[1].Value.ToString() == "False")
      {
            grid.Rows.Remove(row);
      }
}

grid.GridElement.EndUpdate();

AND like that:

grid.GridElement.BeginUpdate();

IEnumerable<GridViewDataRowInfo> uncheckedRows = grid.Rows.Where<GridViewDataRowInfo>(row => row.Cells[1].Value.ToString() == "False");

foreach (GridViewDataRowInfo uncheckedRow in uncheckedRows)
       grid.Rows.Remove(uncheckedRow);

grid.GridElement.EndUpdate();

BOTH WAYS DON'T  WORK... 

Hi,

 

Any reason for the ListElement of RadDropDownList showing the ToolTip when we have the RadDropDownList.ShowItemToolTips = False?

 

Another thing how we can access to the RadDropDownList control from the ListElement control? Imagine we catch the MouseHover event from ListElement and want to access to the parent control (the RadDropDownList control)?

 

Thank You
