I've added an Unbound column to grid for adding combo control in it. I tried to add UltraDropDown/UltraCombo both through code and at design time but it doesn't show in grid. I tried both with EditorComponent and ValueList properties. Although it's not giving any error but it doesn't show up in grid.If I replace this UltraCombo with check box it works perfect both at design and run time.
Hi,
What's the DataType of the unbound column? If you did not set it, it will be string by default.
How are you populating your DropDown/Combo? Are you setting the ValueMember and/or DisplayMember?
When you say "it doesn't show in grid" do you mean that you do not even see a dropdown arrow in the grid cell when you click on the cell? Or do you see the dropdown arrow but are unable to drop it down?
Are you setting any other properties on the unbound column, such as the Style property?
Are you loading a Layout or a Preset or do you have code in the InitializeLayout event or some other event that might be overriding the settings you are applying to the unbound column?
Mike the only mistake was the event.
Actually my task is to show different type of input controls in single column in each row depending on the value of data.
e.g. in bound dataset I have a field named "type" that defines the type of some info and depending on value of type I've to show DatePickers, Checkbox, combo, textbox in single column of grid in each row.
I hope you may have understood my requirement, I don't know is it possible by any solution or by some tweak.
Please suggest me some solution and event that I should use to do this.
Thanks alot for your assistance.
Hi, I am having the exact same issue with my ultra combo control as explained here. I am using ultra combo to populate a data table values from database in the dropdown in a grid. The package is returning only one column from one of the table in the database. I can get the dropdown button in the cell as expected, when I click that button, I find no values but a scroller in the dropdown.
Can somebody please let me know how do I parent my control?
If you are experiencing the same issue, then presumably the same fix which is already described here should apply. Is the UltraCombo control you are using on the form?
BTW... UltraDropDown is generally a better choice than UltraCombo for a dropdown list in a grid cell - although both will work.
This is a windows application I am working on and it has been developed in MVP pattern. The control is used in the view.cs. I am not sure what do you mean by "parent the control by adding it into the form control collection". Sorry, but I am really new to infragistics.
Are you using Windows Forms? If so, then presumably the controls like the grid are on a form. If not, then what platform are you using?
Windows Forms isn't really designed for the MVP pattern. So I really don't know what your application is doing or what your view.cs class is.
Hi Sir,
Ok, please answer this question - What if I select a dataTable as the data source of an UltraDropDown and I am fetching a single column (of a certain table) from the database to this dataTable.
I have seen that we fill values into a dropdown list in the terms of key-value pairs i.e. each value in my list must have an index. Then how do I assign indexes to the values I am fetching from database as explained above?
Thanks a lot,Harshit
The values are coming up in dropdownlist now and when I am saving the record after selecting a certain value, it does get saved in database but doesn't stay in UI dropdown textbox. Also, This grid is getting loaded with certain values as well, but no value get selected by default in the dropdown textbox, although there is a value present in database.
Could you please help me out?
Thanks,Harshit
Yes, this was the issue. Now the values have been populated. I know this was a sill one but thanks a lot.
Now, in this form, I have a UltraTextEditor, whose value is getting populated from a previous page. This value is present in the dropdown, that we have implemented. I need the default selected value of this dropdown to be the same value that is present there in this ultratexteditor. Is it possible?
Note: since my datatable(that contains the VALUELIST getting populated in the dropdown) has only one column, I don't have a n Index for the dropdownitems.
Hi Harshit,
Well.. it's hard to tell from just a code snippet, but it looks like you said your data source has only one column and you are hiding that column.
uddClini_bud_id.DisplayLayout.Bands[0].Columns["BUD_ID"].Hidden = true;
So that would certainly explain all of the behavior you are describing. You are hiding the only column in the dropdown, so there's nothing to display.
This is my current code in View.cs
BindingContext bc = new System.Windows.Forms.BindingContext();
uddClini_bud_id.BindingContext = bc;
//e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].DefaultCellValue.Equals(uteBindBudId.Text);
uddClini_bud_id.DataSource = Lookup.ClinicalBudIdMapping.ClinicalBudIdMappingDt;
uddClini_bud_id.ValueMember = "BUD_ID";
uddClini_bud_id.DisplayMember = "BUD_ID";
uddClini_bud_id.DropDownWidth = 250;
//uddClini_bud_id.DisplayMember.StartsWith("BUD_ID", true, null);
uddClini_bud_id.DisplayLayout.Bands[0].Columns["BUD_ID"].Width = e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].Width;
e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].ValueList = uddClini_bud_id;
e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].ValueList.ShouldDisplayText.Equals(true);
//e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].DataType.ToString();
//e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList;
e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].FilterEvaluationTrigger = FilterEvaluationTrigger.OnEnterKeyOrLeaveCell;
e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].FilterOperandStyle = FilterOperandStyle.DropDownList;
e.Layout.Bands[1].Columns["CLIN_BUDGET_ID"].FilterOperandStyle = FilterOperandStyle.Edit;
And this is there in the designer.cs of this form. Some of it (the last 5 lines) got created by itself and the rest of it has been added by me.

I think the image has been attached now.
Also, I was talking about FilterOperandStyle.
Though, you got it right sir, this is exactly the issue I have. However, I have checked for appearance and creationFilter/draw filter. These have not been applied in my code. I don't know where to find StyleManager.Load. I understand that this is something done inside my code only, something is sort of setting the visibility of these values to false. but I am unable to find that thing.
Do you think I should start over by using UltracomboEditor? or anything else?
