In Silverlight how do you set the HeaderStyle of a dynamic DataGridColumn -

-

I have a data grid and I'm dynamically adding this grid to my ViewModel column. The user has a setting dialog, where they can show which columns in this data grid. The problem I am running is that I do not know how to set the header style on one of these datagrid columns created in my ViewModel.

The most basic version of this will be to add tooltips to these dynamic columns on the DataGridColumnHeader. Note that these columns are not defined in XAML due to their dynamic nature, most columns are data-driven and thus are not known at the time of compilation.

Bonus points How to add a button to this style and how to set it up or command property, so that I can remove the column from the grid (x image on one button in the column header) Imagine, when I click it, I want to remove the column.)

You Specify the header style in the code like this: - 

  style header style = new style (TypeGridColumnHeader); HeaderStyle.Setters.Add (New Setter (ToolTipService.ToolTipProperty, "Hello World")); YourDynamicColumn.HeaderStyle = headerStyle;

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.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
