c# - Context menu items and subitems -

-

I have a context menu inside the form.

For some reason, I wrote context menu together so I wrote this peace code: 

  int a = 0; Leading (Menstep 1. Items with Toolstriptyme in reference) {cum. Text = "menu" + A. Toasting (); One ++; }   
 But the main items change successfully, but if subitems do not change then how can I access those subitems too?  
 PS: I can not add one image because I am new to this forum, what I am saying, I hope you will get this idea.  
 Thank you!   
 
 
 You need to enter  ToolStripDropDownItem  and  DropDownItems  property. And, of course, update it again  
 Here's the sample:  
  Public Zero ChangeMenu Name (ToolStripTime Collection Archive) {foreach (Toolstrip in the collectionMost item item) {item .Name = "new name"; If (item is toolstrip dropdown item) {ToolStripDropDownItem dropdown = (ToolStripDropDownItem) item; If (dropdowndown.downupdotts.count> gt; 0) {this.ChangeMenuItemsNames (dropDownItem.DropDownItems); }}}}   
 How to use:  
  this.ChangeMenuItemsNames (this.contextMenuStrip1.Items);

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...
