delete dataGridView row [modified]

[jashimu]

Hi everyone, I am having some deficulty delete dataGridView rows From My DataGridView. I tried following:

for(int j =0;j<this->s_dataGridView->Rows->Count;j++)
{
this->s_dataGridView->Rows->RemoveAt(j);
}

and

int j = this->s_dataGridView->RowCount;
while(j<=0)
{
this->s_dataGridView->Rows->RemoveAt(j);
rowCount --;
}

it seems like not working. Yes I found My own Solution this is how it works when the entire row collection is needed to delete;

for each (System::Windows::Forms::DataGridViewRow^ row in this->securityCodedataGridView->Rows)
{
this->securityCodedataGridView->Rows->Remove(row);
}

Explanation:

//wrong code
for(int j =0;j<this->s_dataGridView->Rows->Count;j++)
{
    this->s_dataGridView->Rows->RemoveAt(j);
}

//right code
// the rows goes from 0 to count-1
for(int j =0;j<this->s_dataGridView->Rows->Count-1;j++)
{
    this->s_dataGridView->Rows->RemoveAt(j);
}

and again

//wrong code
int j = this->s_dataGridView->RowCount;
while(j<=0)
{
   this->s_dataGridView->Rows->RemoveAt(j);
   rowCount --;
}
// right code
int j = this->s_dataGridView->RowCount-1;
while(j>=0)
{
   this->s_dataGridView->Rows->RemoveAt(j);
   j--;
}

Hi barbetto80, Thanks so much for your help. Sometimes little mistake can go very wrong. Now it is working. thanks again

the logical approach:

while(RowCount!=0) Rows.RemoveAt(0);

the smart approach:

Rows.Clear();
