Hello Jukka,

I tried this and it always works fine for me so I attached my sample to this post for you. Please review it and feel free to let me know if I
misunderstood you or if you have any other questions.

Thank you Boris!

That solution worked for me. I will try now to apply that for my solution.

Hello Jukka,

Did you have the time to look at this? Please let me know if you face any issues, I will be happy to assist you further on the matter!

Hi Boris,

I tried to add it in the code I am maintaining what you proposed like below. (The data set is chosen in a later phase of the code.)

But there is probably something missing because this has no affect.

Jukka

private void grdStandards_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
grdStandards.DisplayLayout.Bands[0].Columns[0].Header.Caption = Texts.resCalibratorCol1;
grdStandards.DisplayLayout.Bands[0].Columns[1].Header.Caption = Texts.resCalibCalibrator;
grdStandards.DisplayLayout.Bands[0].Columns[2].Header.Caption = Texts.resCalibCurrentLot;
grdStandards.DisplayLayout.Bands[0].Columns[3].Header.Caption = Texts.resCalibConcentration;
grdStandards.DisplayLayout.Bands[0].Columns[4].Header.Caption = Texts.resCalibDilution;

grdStandards.DisplayLayout.Bands[0].Columns[0].Width = 45;
grdStandards.DisplayLayout.Bands[0].Columns[1].Width = 115;
grdStandards.DisplayLayout.Bands[0].Columns[2].Width = 115;
grdStandards.DisplayLayout.Bands[0].Columns[3].Width = 120;
grdStandards.DisplayLayout.Bands[0].Columns[4].Width = 90;

// Input masks
grdStandards.DisplayLayout.Bands[0].Columns[0].CellActivation = Activation.NoEdit;
grdStandards.DisplayLayout.Bands[0].Columns[0].TabStop = false;
grdStandards.DisplayLayout.Bands[0].Columns[2].CellActivation = Activation.NoEdit;
grdStandards.DisplayLayout.Bands[0].Columns[2].TabStop = false;
grdStandards.DisplayLayout.Bands[0].Columns[3].CellActivation = Activation.NoEdit;
grdStandards.DisplayLayout.Bands[0].Columns[3].TabStop = false;
grdStandards.DisplayLayout.Bands[0].Columns[4].CellActivation = Activation.NoEdit;
grdStandards.DisplayLayout.Bands[0].Columns[4].TabStop = false;

//set min and max values to Dilution 1+ column.
this.grdStandards.DisplayLayout.Bands[0].Columns[4].MinValue = NumberFormat.GetIntegerMinValue(ViewAssayStdData.pxNumberFormats, "sDilRatio");
this.grdStandards.DisplayLayout.Bands[0].Columns[4].MaxValue = NumberFormat.GetIntegerMaxValue(ViewAssayStdData.pxNumberFormats, "sDilRatio");

<-- new code starts here

const string sDilutionValueList = @"DilutionValueList";

if (!e.Layout.ValueLists.Exists(sDilutionValueList))
{
ValueList svl = e.Layout.ValueLists.Add(sDilutionValueList);
svl.ValueListItems.Add(1, "1");
svl.ValueListItems.Add(2, "2");
svl.ValueListItems.Add(3, "3");
}
this.grdStandards.DisplayLayout.Bands[0].Columns[4].ValueList = e.Layout.ValueLists[sDilutionValueList]; 

<-- new code stops here

cmbCalCalibrators.EditModeOverride = false;
e.Layout.Bands[0].Columns[1].EditorControl = cmbCalCalibrators;

e.Layout.Bands[0].Columns[0].SortIndicator = SortIndicator.Ascending;
}

Thank you for checking,

We decided to do the list based on an editor control / combo box instead.

Thank you very much, Boris, for your help !!

Hello Jukka,

I am checking about the progress of this issue. Please let me know If you need any further assistance on this.

Hello Jukka,

Earlier, you responded to Mike that the cell is editable, but it seems that right before assigning the 'ValueList' to the column, you are setting its cells' activation to 'NoEdit'. This makes it impossible to drop down the 'ValueList', since you are not able to enter into edit mode, i.e. you have a 'ValueList' assigned, but you are not able to "access" it.
