Hi,

I am using ListView Control.I created 4 Columns .when i gave a try to run my form,I got an error:
"Cannot implicitly convert type 'string' to 'System.Windows.Forms.ColumnHeader."

The error is in this code snippet of Form.Designer.cs

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(469, 359);
this.Controls.Add(this.listView1);
this.Name = "Form1";  ' --- here i got an error ---
this.Text = "ListView Demo Form";
this.ResumeLayout(false);

Could anyone explain about this error?

Regards,
Chaithu

It sounds like you just need to use the Text property in that Line.

Hope this will solve your problem.

Fine.

Never use IDs named like label1 text3, etc. This actually violates (good) Microsoft naming conventions (FxCop won't pass it). Always give semantic names.

I think he got the idea 2 years ago

Solution 4

PictureBox pictureBox1 = new PictureBox();
public void CreateBitmapAtRuntime()
{
pictureBox1.Size = new Size(210, 110);
this.Controls.Add(pictureBox1);

Bitmap flag = new Bitmap(200, 100);
Graphics flagGraphics = Graphics.FromImage(flag);
int red = 0;
int white = 11;
while (white <= 100) {
flagGraphics.FillRectangle(Brushes.Red, 0, red, 200,10);
flagGraphics.FillRectangle(Brushes.White, 0, white, 200, 10);
red += 20;
white += 20;
}
pictureBox1.Image = flag;

}

Try this,

Its just that its not the same property

after this conversion you should be up and running for sure

The problem was solved 2 and a half years ago and the OP actually confirmed it. This has got nothing to do with the question

Dr Drastic 24-Feb-14 2:07am

I apologize,

I had multiple windows open and pasted into the wrong one.

That's why it has nothing to do with the question.

Solution 5

That should be runtime exception(you make to change the Form name while sometime) ... You Make to delete that code(That No Problem in your output).

Solution 1

Does your listview have a column named "Name" or some other control with the name "Name"? Try changing it and have another go. Have a look at the link to another forum with a similar question.

Good luck!

Text, not Name. Please, don't mislead OP.

M.CHAITHANYA reports that changing the text of columnheader from "Name" to "Name1" did the trick so my answer wasn't misleading at all but actually very helpful.

Sergey Alexandrovich Kryukov 20-May-11 23:42pm

Thanks for this note. I now see where I was wrong, sorry for my mistake. I re-voted by 5.
