funtion definition should be same when ever you override any function.
number of arguments are different. it should be like
protected override void OnMouseDown(object sender,System.Windows.Forms.MouseEventArgs e) <br />
{ <br />
}

|

I have tried this also.I got error
'DTable.MyDataGrid.OnMouseMove(object, System.Windows.Forms.MouseEventArgs)': no suitable method found to override
'DTable.MyDataGrid.OnMouseDown(object, System.Windows.Forms.MouseEventArgs)': no suitable method found to override

do one thing see the definition of default MouseMove event then try your self

Hi,
there are basically two ways to set an event handler:
1) create a handler, name it whatever you want, and give it an argument list
consisting of an "object sender", and a "SomeEventArgs e".
AND add it to the event using "SomeEvent+=new SomeEventHandler(yourHandlersName);"
This way is always available.
2) If you are creating a derived class, and the base class already has a method
OnEvent(SomeEventArgs e), you can override it with yours in your derived class.
You must use the name as is, and must provide only one argument. And the event
wiring has already been taken care of in the base class.
Normally your OnEvent(e) method should also call base.OnEvent(e)
Now choose either one of these methods, but dont try to combine them for a single
event !

I want to set the width of the column by hardcoding it and don't want to allow it to resize at runtime.
i.e. don't allow user to resize the column width.
How can i do this?
I have tried this code
public void SetColWidth(DataGridTableStyle ts1,int colNum,int width)
// {
// try
// {
// ts1.GridColumnStyles[colNum].Width = width;
//
// ts1.DataGrid.Refresh();
// }
// catch{}
//
// }
private void button1_Click(object sender, System.EventArgs e)
{
// DataGridTableStyle ts1 = dataGrid1.TableStyles["dtTest"];
//
// SetColWidth(ts1, 1,10);
}
but its not working !Can anybody have any idea!
I have to do this in:
language-C# Windows application
version-.net 1.1 or 2003

Hi Bhavana,
It is very simple.
Right click the data grid. go to properties.
Go to the last selection criteria --->Misc-> Columns.
you must have added your columns and column headers over here.
If not then you can add them over here.
For every column, for resizable criteria choose false. It is true by default.
I hope it works

Well, I am working on 2005 version.
Still, try to choose the property of the data grid which allows you to add columns.
There should be a property called as columns, where you can add the collections.
If you find it, then for every column that you add, you can set resizable to false.
Please see if you can do it.

if u are working i will let u know my problem !
may it will make a bit easier!
see in the second URL there is a class MyDataGrid which is inherited from DataGrid
which have two protected override funtions OnMouseMove and OnMouseDown which were not working then i realize that may the events should be registered and i tried this syntax to register
this.dataGrid1.MouseMove += new System.Windows.Forms.MouseEventHandler(this.OnMouseMove);
this.dataGrid1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.OnMouseDown);
where i got errors like
Method 'System.Windows.Forms.Control.OnMouseDown(System.Windows.Forms.MouseEventArgs)' does not match delegate 'void System.Windows.Forms.MouseEventHandler(object, System.Windows.Forms.MouseEventArgs )'
Method 'System.Windows.Forms.Control.OnMouseMove(System.Windows.Forms.MouseEventArgs)' does not match delegate 'void System.Windows.Forms.MouseEventHandler(object, System.Windows.Forms.MouseEventArgs )'

something like this should work while initializing the component
this.dataGridView1.Columns[0].Resizable.Equals(false);
However, I dont know how far this will work in 2003.

create an event handler for every DataGrid Column and its default width there
myDataGridColumn.WidthChanged+=new EventHandler(myDataGridColumn_WidthChanged);<br />
<br />
private void myDataGridColumn_WidthChanged(object sender, EventArgs e)<br />
{<br />
myDataGridColumn.Width=50;<br />
}
|
|
|
|
|
error
'System.Windows.Forms.DataGrid' does not contain a definition for 'WidthChanged'
|
|
|
|
|
event is not present for data grid its for the DataGride Columns(Which are present in GridColumnStyle)
|
|
|
|
|
ya !
i know !
so do u have any idea what should i have to do?
|
|
|
|
|
go in Property od data grid and then click in TableStyle Then Go to GridColumnStyle. There see the name of your Columns and create event for every Columns as I said
|
|
|
|
|
i have done like this earlier!
but after setting the width when we run the program initially the widht is same as we coded but when mouse moves to the column header it allows user to cahnge the widht and i want to disallow this for user!
i.e. to fix the column width at coding time and disable resizable functioanlity for user.

Hello Bhavana,
perhaps this should work.
Search for, where the controls are being initialized. Below the initialization of the datagrid control, each column is being initialized.
for each column, or the column that you require, paste this code
this.Column1.Resizable = System.Windows.Forms.DataGridViewTriState.False;
Please tell me if it works. hopefully, it should.
