Problem getting Image-UDF onto mainform

Fabian Krull

Hy all,



i just tried to get a UDF-PictureBox onto the mainform (Articles) with only partial success.



What i want:

in simple words, a copy of some picture-UDFs on the main form _with_ the option to change images.



How far i got:

Adding the new picturebox was no problem - as well as diplaying the actual picture - all works.

The problems start when i try to implement the change-picture function. I tried several approaches - sadly none of them work.



i appended a simple test-code to demonstrate the issues. this code is not exactly the one i tried, it implements all the different tries i did.



[CODE]

try

{

SwissAddonFramework.UI.EventHandling.ItemEvents.ClickEventHandler clickEvent =

delegate(SwissAddonFramework.UI.EventHandling.ItemEvents.Click cl)

{

try

{

//the two ways i tried to reference the UDF. Same results for both ways

PictureBox pb = pVal.Form.UDFForm.Items["U_cpBildOrder1"] as PictureBox;

//i think this is the "best-practice" way, is it?

PictureBox pb = PictureBox.GetFromUID(pVal.Form.UDFForm, "U_cpBildOrder1");



//tried to simulate a click on the UDF - no result, not even an Exception

pb.Click(SwissAddonFramework.UI.Components.Item.ClickType.Double);

//directly set the image - no result, also no exception

//(BUT: if i do not load item-data before clicking my dummy, it works)

pb.Picture = @"00.jpg"; //also tried an absolute path - same result

//check: setting a text-udf

//this works, even if the code above has failed to set the image

TextEdit te = TextEdit.GetFromUID(pVal.Form.UDFForm, "U_cpZusText");

te.Value = "asdasddasdasd";

//some things i also tried - most of it makes no sense, but i'm despaired, so i tried anyway...

pb.Refresh();

pb.Update();

pVal.Form.Update();

pVal.Form.UDFForm.Update();

}

catch(Exception exx)

{

System.Windows.Forms.MessageBox.Show(exx.Message, "Error");

}

};

//this is my testbox on the mainform, in final this one shall display the image, wich i already accomplished within another testcase.

//in this case it is mainly a PictureBox-Button-Perversion

PictureBox test = PictureBox.CreateNew("testPic");

test.Left = 0;

test.Top = 0;

test.Width = 100;

test.Height = 100;

test.Visible = true;

pVal.Form.AddItem(test);

pVal.Form.Update();

test.AddHandler_Click(ModeComponent.FormModes.ALL, null, clickEvent);

}

catch(Exception ex)

{

System.Windows.Forms.MessageBox.Show(ex.Message, "Error");

}

return true;

[/CODE]





Hopefully, anybody can halp - this functionality is kind of critical to the imminent switch to SAP.



Thanks in advance,

Hi Fabian,



I tried your code and got the same result.



When using the UI API PictureBox object directly (without coresuite framework) the result is the same:



SAPbouiCOM.Form sapForm = SwissAddonFramework.B1Connector.GetB1Connector().Application.Forms.Item(pVal.Form.UDFForm.UniqueID);

SAPbouiCOM.PictureBox pb = (SAPbouiCOM.PictureBox)sapForm.Items.Item("U_Picture").Specific;

pb.Picture = "newpicture.jpg";



-> The PictureBox.Picture property still has the original value.



It seems that once it has been set it cannot be changed.



Here is a workaround you can try - update the image file through the DI and reload the form:





SAPbobsCOM.Company company = SwissAddonFramework.B1Connector.GetB1Connector().Company;

SAPbobsCOM.Items item = (SAPbobsCOM.Items)company.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oItems);

item.GetByKey(pVal.BusinessObjectKeyString);

item.UserFields.Fields.Item("U_Picture").Value = "newpicture.jpg";

int err = item.Update();

if (err != 0)

{

string errMsg = company.GetLastErrorDescription();

throw new Exception(string.Format("{0}: {1}", err.ToString(), errMsg));

}



pVal.Form.Close();

Form.OpenFormByKey("4", pVal.BusinessObjectKeyString);

Hello Anders,



thanks for your reply but i _just_ figured out how to do this and implementing it into our production system..

the solution to this was much simpler than i thought, i just went down the wrong path



for all of you who seek knowledge this is the path of enlightment:^^



[CODE]

PictureBox test = PictureBox.CreateNew("testPic");



test.Left = 0;

test.Top = 0;

test.Width = 100;

test.Height = 100;

test.Visible = true;



//now here's the magic^^

test.DataBind = DataBind.CreateNew();

test.DataBind.SetBind(true, "U_cpBildOrder1", "OITM");



pVal.Form.AddItem(test);

pVal.Form.Update();

[/CODE]



using this approach right away gives the picturebox the full functionality, including doubleclick and ctrl+doubleclick etc...
