The <code>SaveFileDialog</code> has a property intended for this purpose: <a href="http://msdn.microsoft.com/en-us/library/system.windows.controls.savefiledialog.defaultfilename%28v=vs.95%29.aspx" rel="noreferrer"><code>DefaultFileName</code></a> using Silverlight or <a href="https://msdn.microsoft.com/en-us/library/system.windows.forms.filedialog.filename(v=vs.110).aspx" rel="noreferrer"><code>FileName</code></a> using .NET 

Your (uncompilable) code from the question would become:

<pre><code> private void buttonSave_Click(object sender, EventArgs e) 
 {
 SaveFileDialog mySaveFileDialog = new SaveFileDialog();
 //Silverlight
 mySaveFileDialog.DefaultFileName = myDataGridView.SelectedCells[2].Value.ToString();
 //.NET
 mySaveFileDialog.FileName = myDataGridView.SelectedCells[2].Value.ToString();
 }
</code></pre>

The problem is that you need to use:

<pre><code>myDataGridView.SelectedCells[0].Value.ToString();
</code></pre>

instead of

<pre><code>myDataGridView.SelectedCells[2].Value.ToString();
</code></pre>

Until you don't select 3 or more cells with mouse or whatsoever. You can index like <code>[2]</code>

<pre><code>private void buttonSave_Click(object sender, EventArgs e) 
{
 SaveFileDialog saveFile = new SaveFileDialog();
 saveFile.FileName = myDataGridView.SelectedCells[0].Value.ToString();
 saveFile.ShowDialog();
}
</code></pre>

Does this work for you?

Your code should look the following way:

<pre><code>private void buttonSave_Click(object sender, EventArgs e) 
{
 SaveFileDialog saveFile = new SaveFileDialog();
 saveFile.FileName = myDataGridView.SelectedCells[2].Value.ToString();
 saveFile.ShowDialog();
}
</code></pre>

Use <a href="https://msdn.microsoft.com/en-us/library/system.windows.forms.filedialog.filename(v=vs.110).aspx" rel="nofollow">FileName</a> but set the filename before showing the dialog.

I would like to create <code>SaveFileDialog</code> with <code>default file name</code> from value <code>DataGridViewCells</code>

So far I tried

<pre><code>private void buttonSave_Click(object sender, EventArgs e) 
{
 //first
 //mySaveFileDialog.FileName = myDataGridView.SelectedCells[2].Value.ToString();
 //second
 SaveFileDialog saveFile = new SaveFileDialog();
 saveFile.FileName = myDataGridView.SelectedCells[2].Value.ToString();
 saveFile.ShowDialog();
}
</code></pre>

Can anyone help me solve this?
