Pete, thanks for the great recommendations. What they offer is fastastic!

I would suggest since they are coming out of your personal funds you go with the DevExpress components. I know every once in a while they offer some of the components free, like their editor controls. DevExpress

does C# have any function or method that I can call to get the lon and lat from some reference I have with regards to the pic and a mouse position. Hope the questions is clear...
Thanks

No, how could it ? It would need to know the starting position and the scale of the image. Even then, not all map images will have steady change of lat/lng.
You need to write your own code, based on what you know about the image you're displaying.

man...that is what I thought, its tough

Yeah, it's always nicer to find stuff is supported for you, but in this case, I don't see any way it could take a bitmap and give lat/lng, and it should be pretty easy to work out, just find out the co-ords for the corners of your bitmap and do the math to track the rate of change to the mouse.

Dear all,
I am making a window form and using 1 datagridview control on it. The datagridview itself supports auto sort, but it is only valid with all column type except image column.
Please give me your all solutions on this issue.
Thanks.

from where you are retriving image name.Regardless of any source(s).Just do one thing might it work.Take all the image name(hope all r unique) and store them in array list.Now sort the list and store all column base on image name.

Thanks Chintan.Desai for your reply.
My problem is really that when my datagridview load all data completely, click on each column, except image column, and every things are ok. But when i click on image column, it is not active.
If I put all my data in array list and each column use 1 array list, we will have many array lists. This is quite difficult for managing code.
Please send me your all other suggestions
Thanks for all help.

No buddy,Arraylist is one type of container,so store every image name in that arraylist and then use Sort function from array list class and sort them.

I solved my problem by using IComparer interface. I have a object and image is one of its many properties, I wrote a lass for compare to object, and property used for compare is the image type (each product have 1 image type).And the last, I create an array list and sort all this array follows my new class which implements from IComparer.
<br />
public enum SortDirection<br />
{<br />
Ascending,<br />
Descending<br />
}<br />
class ElementSorting : IComparer<br />
{<br />
<br />
private SortDirection m_direction = SortDirection.Ascending;<br />
<br />
public ElementSorting() : base() { }<br />
<br />
public ElementSorting(SortDirection direction)<br />
{<br />
this.m_direction = direction;<br />
}<br />
<br />
int IComparer.Compare(object x, object y)<br />
{<br />
<br />
ABCElement elementX = (ABCElement)x;<br />
ABCElement elementY = (ABCElement)y;<br />
<br />
if (elementX == null && elementY == null)<br />
{<br />
return 0;<br />
}<br />
else if (elementX == null && elementY != null)<br />
{<br />
return (this.m_direction == SortDirection.Ascending) ? -1 : 1;<br />
}<br />
else if (elementX != null && elementY == null)<br />
{<br />
return (this.m_direction == SortDirection.Ascending) ? 1 : -1;<br />
}<br />
else<br />
{<br />
return (this.m_direction == SortDirection.Ascending) ?<br />
elementX.Type.CompareTo(elementY.Type) :<br />
elementY.Type.CompareTo(elementX.Type);<br />
}<br />
}<br />
}<br />
Thanks

I generated columns and rows in a datagrid. when I click a button while the radiobutton is checked i was able to convert the cell backcolor.
My requirement is when i clicked the cell its rowindex, columnindex will get added to a listbox. which later will stored. My code snippet looks like this
private void dgv1_CellClick(object sender, DataGridViewCellEventArgs e)
{
foreach (DataGridViewRow row in dgv1.Rows)
{
if (radioButton1.Checked == true)
{
row.DataGridView.CurrentCell.Style.BackColor = Color.Black;
//Try to add the cell index to listbox collection item
//listBox1.Items.Add(row.DataGridView.CurrentCell.RowIndex);//it stores the index total row no. times
//listBox1.Items.Add(row.DataGridView.CurrentCellAddress);//need to reduce it to only one
}
help me.

hi,
I have two forms Form1 and Form2. On Form1 i have a data grid that has a data in 3 columns, now on button click i want to send data of first row to Form2 that has 3 textboxes, so that the text boxes have the corresponding values (for eg Name,City,Country). I tried to make 3 public properties and assign the values of the grid cells to them and then tried to call these properties on FOrm2 to populate the text boxes, but they show up empty, because to be able to access Form1's property, i need to declare and initialise Form1's instance, so each time a new instance is created, the property would contain null values.Please help

u can pass the instance of first form to second form in second forms constructor.

Except that would be nasty...

public partial class Form2 : Form<br />
{<br />
Form1 frm1;<br />
public Form2()<br />
{<br />
InitializeComponent();<br />
frm1 = new Form1();<br />
}<br />
Is that what u wan to say ?

No, that is an utter disaster, it cannot work. The Form1 inside form2 is completely irrelevant to the Form1 that you are working with.

I assume they are not called that....
If you want to pass data from form1 to form2, pass it through the constructor or through properties, if you want to pass data from the child to the parent, set up delegate methods to do so. Whatever you do, set up the smallest scope properties you can, i.e. set up a string property to set the text of a textbox, rather than making the textbox itself public.

Hi Chris....thts what I precisely did....i created 3 public properties on Form1 each to capture cell values of the grid data and then in Form2 I created an instance of Form1 and using it i accessed those properties, but since each time the Form2 loads, it would create a new instance which wud be null, the text boxes are empty. Now, do we have a way to modify this to work

Yep - that's the issue. A new instance of Form1 has nothing to do with the instance in use in your program. I recommend reading a book on OO.

Going from form2 to form1, you should use delegates.

Hey Chris and Rahul.....thannx a lot ..constructor technique worked .....but is there any other way to do it?
|
|
|
|
|

obviously when you create any object instance, it allocate new empty memory. So just do one thing in form1 click event.create form2 instance, after then assign grid cell in form1 to form2 public property.Now in form2 load event assign that property to each textbox of form2.Now show form2.
