Hello,
I have to show a ContextMenuStrip in the Header of the DataGridView.
In the event
ColumnHeaderMouseClick do datagridview i catch the coordenates e.X and e.Y of the mouse, but the ContextMenu doesn't appear where the mouse is, i always
appears in the first columns.
look the image
thank you a lot

The e.X and e.Y coordinates are probably local. Convert them to screen coordinates before showing the context menu:
Point localPoint = new Point(e.X, e.Y);
Point screenPoint = dataGridView.PointToScreen(localPoint);
myContextMenu.Show(screenPoint...);

Good luck with that! You won't find one. And noone is going to write the code for you.

just do your work...

It would appear to me that you are the one using profanity (badly spelled profanity at that)

True, you said "provide me code". But "provide" implies that the person you asked must do the work to create the code, or do the work to find the code. Either which way, you are asking others to do your work. Perhaps if you had phrased your question in a less provokative way you would get a better response. e.g. "Help me find the code" that implies to are trying to do the work but need assistance. We like to help people. We especially like to help people that show that they are trying to help themselves.

 I can only imagine that is some idiomatic expression literally, rather than figuratively, translated.

You should know by now that when you post to these forums, the people who want to help you are volunteers and have no obligation to answer your questions or write your code. This subject matter of converting pdf to image is primarily undocumented and is left to expensive third party controls to solve the problem and you will just have to live with it.

Hello,
I have a data grid view, and what I am trying to do is, grab all the column headers and put them into a combo box or list box.
what I have so far is:
foreach (DataColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.ToString());
}
I get an error with this, it is:
"Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.Data.DataColumn'"
Any help would be apreciated.
Thanks
J

you can try:
foreach (DataColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}
|
|
|
|
|
|
Thanks... The end result that I ended up with is:
foreach (DataGridViewColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}
|
|
|
|
|
this.dataGridView1.Columns returns a collection of GridViewColumn, not DataColumn. In this case, the column returned is a specialized version of GridViewColumn which contains a textbox.
<br />
foreach (GridViewColumn in this.dataGridView1.Columns)<br />
{<br />
this.listBox1.Items.Add(column.HeaderText);<br />
}<br />

Thank you for your help, I added a identifyer, and it worked great! Thanks.
Here is the end result.
foreach (DataGridViewColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}

hi all
abstract class c
{
abstract function()
}
class c1:c
{
override fucntion()
{
//
}
void function()
{
}
}
class c2:c1
{
c1 obj=new c1()
obj.//how do i differenciate that i wanna call overrided function and ordinanry function of c1
|
|
|
|
|
c.function will always call the overrided method. You cannot call the base one. If that's what you want, don't use overrides, using hiding:
class Base
{
public void Foo() { ... }
}
class Derived : Base
{
public new void Foo() { ... }
}
Base obj = new Base();
obj.Foo();
Derived derived = new Derived();
derived.Foo();

Hello,
I'm having a problem that I thought would be very easy to fix. It could just be something small I am missing. I am loading a string that contains an XPath query. Inside the string I have a couple variables being loaded from an XML request. My line: XmlNodeList regionList = root.SelectNodes(xpathRegion); is throwing an exception when the variable includes an ' like Amp'd for example. I can check for characters easy enough and remove that character, but I actually need to leave it as the query needs to search based on the exact name.
I am trying the following:
string oldText = catName;
string newText = oldText.Replace("'", "\\'");
I figured this would escape the first slash, and replace the ' with \' but it actually shows up as \\'
if I change the line to string newText = oldText.Replace("'", "\'"); only the ' shows up in the string.
I can't seem to get newText to contain Amp\'d so that when used in the XPath it finally ends up the way it was.
Is there a different method I should use, or am I making some type of beginner error? Thanks,
Forrest

Thanks for the link. This is certainly a great resource to have. It looks like the Xpath string is still blowing up even with a \'
|
|
|
|
|
instead of \', have you tried ' instead?
|
|
|
|
|
Yes, and " Those values are inserted into the string, but I guess it is not read as an xpath query since I still get an invalid token message.
|
|
|
|
|
Try this and see if it works:
string oldText = catName;
string newText = oldText.Replace("'", @"\'");

Thanks Chase. This is exactly what I needed to do to get the string to contain \' BUT it looks like the xpath string is still blowing up when SelectNodes() is called. I don't think it recognizes the escape sequence. I also tried including ' but it didn't recognize that either. I do appreciate the help though.
