Asp.net datagri Copy to clipboard method

Asp tutorial. net datagridview Copy to clipboard method

Copy mode settings

 

Maid copymode = maid copymode. enablewithoutheadertext // sets the replicable mode

 

The datagridview. clipboardcopymode attribute gets or sets a value, which indicates whether the user can copy the text value of the cell to the clipboard, and whether the row title and column title text are included.

 

Namespace: system. windows. forms

Assembly: system. windows. forms (in system. windows. forms. dll)

 

Selected copy

 

Clipboard. setdataobject (datagridview1.getclipboardcontent () // place the data selected by the control to the system clipboard.

 

Datagridview paste

 

Code

If (MAID. value = null)

{

Return;

}

Int insertrowindex = maid. rowindex;

String pastetext = clipboard. gettext (); // obtain data from the system clipboard

If (string. isnullorempty (pastetext ))

{

Return;

}

String [] lines = pastetext. split ('r'); // group by row

Bool isheader = true;

Foreach (string line in lines)

{   

If (isheader)

    {

Isheader = false; // filter operations when the title is included in the replicable mode

    }

Else

    {

String [] vals = line. split ('t'); // grouping by tab space

If (vals. length-1! = Maid)

        {

Throw new applicationexception ("column number error ");

        }

Maid row = maid [insertrowindex];

Row. headercell. value = vals [0];

For (int I = 0; I <row. cells. count-1; I ++)

        {

Row. cells [I]. value = vals [(I + 1)];

        }

Insertrowindex + = 1;

    }

}

 

 

IX. Automatic ID of the datagridview

 

Code

 

Private void maid (object sender, maid e)

        {

// The automatic number is irrelevant to the database tutorial.

Rectangle = new rectangle (e. rowbounds. location. x, e. rowbounds. location. y

, Maid-4, e. rowbounds. height );

 

Textrenderer. drawtext (e. graphics, (e. rowindex + 1). tostring (), datagridview1.

Rowheadersdefaultcellstyle. font, rectangle,

Datagridview1.rowheadersdefaultcellstyle. forecolor, textformatflags. verticalcenter | textformatflags. right );

        }
