celltype = "image" not working after upgrading to 3.0.1.0

[Administrator]

hi,

i have a column in a ggc, not mapped to any column in the datasource, with celltype = "image".

previously i am able to display an image by assigning an imagelist control, and an imageindex. however, after the upgrade i did, the column is no longer showing up.

i tried mapping the column in tabledescriptor to one of the columns specified (type = varchar) in the datasource. now i am able to see the column, but the image is still not showing up.

is there a change in behaviour for celltype = "image"?

need help urgently.

thanks!

Did you add this unbound column to the TableDescriptor.UnboundFields collection?

grid.TableDescriptor.UnboundFields.Add("unbound");
grid.TableDescriptor.Columns["unbound"].Appearance.AnyRecordFieldCell.ImageIndex = 0;
grid.TableDescriptor.Columns["unbound"].Appearance.AnyRecordFieldCell.ImageList = imageList1;
grid.TableDescriptor.Columns["unbound"].Appearance.AnyRecordFieldCell.CellType = "Image";

it did not work. i tried using codes to create a datatable and populate it using a loop.

assigning it as the datasource for the ggc, and i am able to get the image to show up.

however, when i load the datatable from database and assign it to the ggc, i am able to get all columns up. the image column just wont show up.

Here is a little sample showing it working.

If you cannot spot something, if you upload a sample showing the problem, we can try to spot it here.

i am still in the midst of trying to understand the behaviour of ggc in 3010. i have a few findings and they are as follows:

scenarios:
1.
- columns are defined in tabledescriptor of the ggc''s properties in design time, including the 2 columns (no mapping name defined) that the icon will be showing on. setting for the 2 columns:
celltype = image
imagelist = img16x16
imageindex = 0
- assign datatable to the ggc''s datasource
- all columns shows up, except the 2 columns (doesn''t appear on screen at all)

2.
- columns are defined in tabledescriptor of the ggc''s properties in design time, including the 2 columns (no mapping name defined) that the icon will be showing on. setting for the 2 columns:
celltype = image
imagelist = img16x16
imageindex = 0
- define the 2 columns again in unboundfields properties in tabledescriptor.
- assign datatable to the ggc''s datasource
- all columns shows up, including the 2 image columns.

3.
- columns are defined in tabledescriptor of the ggc''s properties in design time, including the 2 columns (no mapping name defined) that the icon will be showing on. setting for the 2 columns:
celltype = image
imagelist = img16x16
imageindex = 0
- define the 2 columns again in unboundfields properties in tabledescriptor.
- assign datatable to the ggc''s datasource
- all columns shows up, except the 2 columns (doesn''t appear on screen at all)

4.
- do not define any columns in tabledescriptor of ggc.
- assign datatable to the ggc''s datasource
- apply following codes:

GridGroupingControl1.TableDescriptor.UnboundFields.Add("Gender")

GridGroupingControl1.TableDescriptor.Columns("Gender").Appearance.AnyRecordFieldCell.ImageIndex = 0

GridGroupingControl1.TableDescriptor.Columns("Gender").Appearance.AnyRecordFieldCell.ImageList = Me.ImageList

GridGroupingControl1.TableDescriptor.Columns("Gender").Appearance.AnyRecordFieldCell.CellType = "Image"

- all columns show up, including the unbounded field "Gender". do note that this Gender does not exist in the datasource.

with the above findings, i am trying to apply scenario 2 into my apps. as it seem for now, it don''t look good.

correction for scenario 2.
- columns are defined in tabledescriptor of the ggc''''s properties in design time, including the 2 columns (MAPPING NAME DEFINED) that the icon will be showing on. setting for the 2 columns:
celltype = image
imagelist = img16x16
imageindex = 0
- define the 2 columns again in unboundfields properties in tabledescriptor.
- assign datatable to the ggc''''s datasource
- all columns shows up, including the 2 image columns.

Do you have a sample project that you can upload where this is not working for you?

[Administrator]

i have attached a sample project. custdb is an mssql 2000 db backup file that the project uses. WindowsApplication1_4180.zip

[Administrator]

Exactly what is custdb, and how do I use it?

It does not appear to be an mdf that I can attach, is it?

[Administrator]

I changed your sample to create a DataTable form code. The only strange thing I noticed was a null reference exception being thrown in the QueryCellStyoeInfo code. I added a check to avoid this so the exception is no longer raised. Exactly what behavior in the sample is not as you expected.

i tried running the changes you made. basically its the same result i got from running through the db as the datasource.

i am trying to get my codes to work and function in the same way as datagrid2 but was not successful.

i dont think i am able to attach actual codes from my project over here. for now, i will try to download 3.2.0.0 and see if i can get it to work in that version.
