I have a datagridview with 10 columns. One of the columns is partially visible when i moved the horizontal scroll bar. I want to make the column fully visible when I clicked one of the cells in it.

Is there any way for doing this?

Hi Manu,

You can use the GetColumnDisplayRectangle method of the DataGridView and the column width to determine wether the clicked cell is partially displayed. If so, use the HorizontalScrollingOffSet property to scroll the DataGridView. The following is a sample:

dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

Rectangle entireRect = this.dataGridView1.GetColumnDisplayRectangle(e.ColumnIndex,false);

Rectangle visiblePart = this.dataGridView1.GetColumnDisplayRectangle(e.ColumnIndex, true);

if (visiblePart.Width < entireRect.Width)

this.dataGridView1.HorizontalScrollingOffset += entireRect.Width - visiblePart.Width;

else if(visiblePart.Width < this.dataGridView1.Columns[e.ColumnIndex].Width)

this.dataGridView1.HorizontalScrollingOffset -= this.dataGridView1.Columns[e.ColumnIndex].Width - visiblePart.Width;

Hello Manulji,
You can change autosizemode of datagriviewcolumns in cell_click event. try like,

Hi Naresh,

Thanks For the response.

We have fixed width columns. The solution that you specified will not work in that case. Is there any other solution?

Hello manuliji,
If you want to keep,fixed width of columns, then what do you mean by "make column fully visible" ?

Hi Naresh,

My grid can only show 5 columns within the gridview area. I have then added two more columns. As a result the horizontal scroll bar appeared. When I moved the horizontal scroll bar the last column is partially appeared in the visible area.

Now what I want is if i click on a cell on the last column, it should be displayed fully in the visible area.

I want the same behavior with the tab and arrow key. IF i press the tab key or right arrow key from a cell left of the partially visible column, the column becomes fully visible.


I am not able to attach a screen shot..
