I want to customize a SharePoint EntityEditorWithPicker so that I can open the picker dialog through a linkbutton. When the user closes the dialog, I want to update the page with the selected values (the results go in rows of custom controls)
This would be the current state of the picker control, with a textbox and the "adressbook" button to open the picker dialog. The resolved result ends up in the textbox
But I want the dialog to open from the linkbutton called "Add Multiple Records". Afterwards I want to handle the results in some sort of callback function.
The above picture represents a custom class derived from EntityEditorWithPicker that I use to let users pick custom data.
The linkbutton is added to a custom control from code behind, there's no aspx or CAML involved. I thought i might add the results to the hidden field I insert together with the button, here's the part of the control that outputs that area.
HiddenField hiddenElement = new HiddenField();
hiddenElement.ID = "hiddenResultElement";
container.Controls.Add(hiddenElement);
LinkButton button = new LinkButton();
button.Text = "Add multiple records";
button.CommandName = "InsertMultiple";
table.Rows[0].Cells[0].Controls.Add(image); // plus sign
table.Rows[0].Cells[1].Controls.Add(button);
I would like to be able to use the linkbutton to open the browse-dialog of the entitypicker, and handle the results using a callback function
I'm currently trying to make the control invisible, and use javascript to click the browse button. But now I'm stuck with how to get to the browse button. Any suggestions?
