Hi Mike,

Thank you for your response. I thought for sure this example code was going to fix my problem. I did not create the grid through the designer and Im finding out now that Im running into a few places where the normal defaults are not being set. I did add this code below in the designer.cs file but it still didnt allow the cell in column 1 of band one to edit the text.

Im not sure if there is another property that is preventing this that didnt get set because I hand coded the whole thing? Any help is much appreciated.

//Code added to the grid (didnt enable the editing of the cell text)

this.ultraGrid1.DisplayLayout.Override.AllowUpdate = Infragistics.Win.DefaultableBoolean.True; this.ultraGrid1.DisplayLayout.Bands[0].Override.AllowUpdate = Infragistics.Win.DefaultableBoolean.True;

Hi,

There's no property you have to set to enable editing. Editing is enabled by default, without setting anything. So if you are unable to edit, it's because something in your application is explicitly disabling editing.

The KB article gives you a fairly complete list of all the ways in which you might have disabled editing. So if you have searched your code for all of those possible ways and you can't find anything, then there are only a few other possibilities.

• You are loading a Layout which is setting one of those properties.
• Your DataSource does not allow editing on that field.

Hi Mike,

Again thanks for all your help. I dont know why setting these to allowEdit/true...ect wouldnt work. Im at a real loss as to why this isnt working. : /  Listed below are all the methods I have tried congruently. You mentioned that possibly the datasource might not allow editing. Is there any code for this you might be able to direct me to? Thank you so much for your time!

            this.ultraGrid1.DisplayLayout.Override.AllowUpdate = Infragistics.Win.DefaultableBoolean.True;
            this.ultraGrid1.DisplayLayout.Bands[0].Override.AllowUpdate = Infragistics.Win.DefaultableBoolean.True;
            this.ultraGrid1.DisplayLayout.Bands[0].Columns[0].CellActivation = Infragistics.Win.UltraWinGrid.Activation.AllowEdit;

            ultraGridColumn1.CellActivation = Infragistics.Win.UltraWinGrid.Activation.AllowEdit;
            ultraDataColumn1.ReadOnly = Infragistics.Win.DefaultableBoolean.False;
            ultraDataBand1.ReadOnly = Infragistics.Win.DefaultableBoolean.False;

            ultraGridBand1.Override.CellClickAction = Infragistics.Win.UltraWinGrid.CellClickAction.EditAndSelectText;

Didn't you say it was column 1 that wasn't allowing you to edit?You are specifying Column 0 here, so you might have the wrong index. I recommend using the column's Key rather than the index to avoid any possible confusion.

Is it only the one column having a problem? Can you edit other columns?

Have you tried reading out the property settings you have set here to make sure they are all still set to what you set them to at run-time? Put a button on the form and Debug.Writeline all of these property values to make sure they are not getting overwritten.

What kind of data source are you binding to? It looks like it's probably an UltraDataSource, so that should be all right.

Try putting a new grid control on the form and bind it to the same DataSource you are using for the real grid and see if the new grid allows editing.

If you want to post a small sample project demonstrating the issue, I would be happy to take a look at it and tell you exactly why you cannot edit the column.

I am unable to edit a cell after locking the row.

this is to lock entire row

Me.ultraGrid1.Rows(10).Activation = Activation.NoEdit

and i need to unlock only one cell

Me.ultraGrid1. Rows(10).Cells("Select”).Activation = Activation.NoEdit

but unable to edit the select column which style is check box.

please help to lock entrie row but allow check box column to edit.

My second thought was that Im using the Creation Filter. Do you think this could possibly be any kind of a problem by it not allowing me to edit a cell. As far as I know this code cycles through all the elements in the grid and does things as you need them to. I compared lines in the designer code with my hand code and I couldnt see anything different that we didnt try to enable the cell editing.

It depends on what your CreationFilter is doing. If you are preventing the cell from creating it's editor UIElements (perhaps because you replacing those elements with your own elements) then that could stop the cell from entering edit mode. But this is very simple to test. Comments out the CreationFilter and see if the problem still occurs.

I guess my last question is about alternative help. Is there any kind of video tutorials or one on one sessions that can help me work with the grid designer?

I'm not aware of any, but I will forward this over to Infragistics Developer Support and see if they can help you there.

Hi Mike,

So I was able to come back to this code today and try out some things. I ended up making a whole new UltraGrid in the designer. When I had just the minimal things in the grid I was able to go and edit the cells. I proceeded to copy over as much code as possible and when I ran im still getting a run time error about the band not having all the columns I thought I added to it through the designer. These were the kind of problems I had at first that made me end up hand coding the whole grid.
