C# Winforms DatagridviewCombobox exception String cannot be converted to class -

-

I am experiencing an exception Detagrivid scene (dropdown menu) and choose a new value from the control embedded in Detagrid Views is done. Combobox is populated by a binding source, which is populated with examples of my class. I can display options in the menu properly, and select one, but changing the focus to change a new control (I think to change that) causes an exception to appear: the system Invalid cast from String stack trace myclass (if I'm correct use of the word) source shows

System.Windows.Forms.DataGridView.PushFormattedValue cascading down System.Convert.DefaultToType < p> another obvious explanation below (the long regret, but I wanted to reproduce it):

I also have an empty class called Apupent, no properties ( The problem occurs when migrant is also a string name property, this New is not it). I have a binding source that is called occupateness source, pointing to people living with its datasource.

I am also called a car, which has a migrant property named Driver.

I do in my Form_lod (), I call Okyupantssors.adanu () to extend the call twice, once CarSource.AddNew ().

I have a Datagreed visual control, which Detasors is CarSource (binding source consisting of the cars) is a column near Dijivi, which displays driver estate cars Karrsor. This is a datagridclobbox column, in which a driver named Dataproopernet is set up.

So what I want is to show the rows of cars Detagrid Vijhuars, a column I could drop down with a Kangiboksi can choose drivers from the current drivers have occupied but I Exceptions get.

Is this something wrong? Can not you use a class examples to populate a Data Grid Vib ComboBex?

My head was scratching, trying to solve it using my google-fu For hours. This link ultimately gave me a good explanation.

The way I decide it, it was to change DisplayMember. I knew about 'Self' who had returned 'this' - I was using it for both DisplayMember and ValueMember, thinking it would only doostring the property from the performer.

Reading your explanation, maybe you do not have DisplayMember and ValueMember set? If this is the case, then try to set them up properly (and do not use the 'this' reference for the display member!) And it can fix it.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.
