Drag drop to item in ListView

Hi,

I have a solution where a user drags data into my application, onto a RadListView. The user drops the data on top of a RadListViewItem representing the subject to added the data to. I have added code for detecting which item that was dropped on (from Telerik documentation), but it always returns null from GetElementAtPoint. I have tried other Points (screen, control, client), but it's allways null.

The RadListView is unbound, in DetailView mode and have an icon and two columns. I don't know if that makes any difference in how this is handled.

private void radListView1_DragDrop(object sender, DragEventArgs e)

{

Point point = radListView1.PointToClient(new Point(e.X, e.Y));

BaseListViewVisualItem droppedItem = radListView1.ElementTree.GetElementAtPoint(point) as BaseListViewVisualItem;

if (droppedItem != null)

{

ListViewDataItem item = droppedItem.Data;

// handle dropped data here

}

I am using Telerik version 2014.1.226.40.

Best regards

Thomas

DateTime Value in gridview to String not in correct format

Hi,

I'm having a hard time trying to get a datetime value from my gridview to string in the correct format that I have set to display on the gridview.

I want: yyyy/MM/dd HH:ss ex. 2020/01/30 14:15

But the result keeps giving me 1/23/2020 2:05:08 PM

Then to string with all the non-alphanumeric removed it gives me: 1232020258PM (noticed it removed any 0s in front of the mins and secs...

I have already formatted the datetime on the gridview to display the correct format. But the value to string still gives me the other format.

I've also tried to grab the data from Sql database instead of gridview, however I still get the same result.

Ultimately, I need the correct format in the string so that I can eventually take it apart again to put in a different table. And why it will be in string is because i need to grab this info to include in the name of the PDF file. Then I'll make a table using info from the name breakdown to pull the PDF to put info a table to select it.

Help? Thank you!!!

My code:

private void radGridView1_CommandCellClick(object sender, GridViewCellEventArgs e)

{

plantCode = radGridView1.CurrentRow.Cells["plantCode"].Value.ToString();

machine = radGridView1.CurrentRow.Cells["machine"].Value.ToString();

ordNum = radGridView1.CurrentRow.Cells["productionOrderNum"].Value.ToString().Substring(0, 7);

ordItem = radGridView1.CurrentRow.Cells["productionOrderNum"].Value.ToString().Substring(8, 3);

apprStatus = radGridView1.CurrentRow.Cells["approvalList"].Value.ToString();

custName = radGridView1.CurrentRow.Cells["addrName"].Value.ToString();

process = radGridView1.CurrentRow.Cells["process"].Value.ToString();

prodCode = radGridView1.CurrentRow.Cells["prodCode"].Value.ToString();

custId = radGridView1.CurrentRow.Cells["custId"].Value.ToString();

approvalTime = Regex.Replace(radGridView1.CurrentRow.Cells["approvalTime"].Value.ToString(), "[^a-zA-Z0-9]", "");

See I already formatted it on the datetime column in the gridview and this works fine displaying in the gridview:

gridViewTextBoxColumn16.DataType = typeof(System.DateTime);

gridViewTextBoxColumn16.FieldName = "approvalTime";

gridViewTextBoxColumn16.FormatString = "{0:yyyy/MM/dd HH:mm}";

gridViewTextBoxColumn16.HeaderText = "approvalTime";

gridViewTextBoxColumn16.IsVisible = false;

gridViewTextBoxColumn16.Name = "approvalTime";

gridViewTextBoxColumn16.ReadOnly = true;
