Hello D@Nish, thank you very much for your response. Is there a way to open the file systematically as soon as the save is complete? Thanks again for your help.

Use Process.Start method once the save is complete. It will open the file in the associated program.

Any alternate or suggestion

The application is halted when it hits a breakpoint. Hence, it will not paint the form.
You can add a "watch" in order to inspect the value though
|

|
Yes you are right but any other way instead of adding watch window because my scenario involves so many controls and grids any how thanks for Helping

Call Application.DoEvents() after setting the textbox value.
while (e) { Coyote(); }

Hello All,
I have list that is globally declared and i have add button which will add one object to the list once it clicked .
I am binding this list to grid .
for the first time when i click add button item is added to the list and binded to grid too.
when i again click the same then it added the item to the list but still not reflected to grid and then i have done some modifictions and get the result.
please find the code
private void btnAdd_Click(object sender, EventArgs e)
{
objSapient.Add(new SapientDetails(txtName.Text,txtSapientID.Text,txtProjectName.Text,txtPhoneNumber.Text,txtExpr.Text));
if (objSapient.Count != 0)
{
grvDetails.DataSource = null;
}
grvDetails.DataSource = objSapient;
}
why do i need to set as datasource to null ?
why just grvDetails.DataSource = objSapient; is not sufficeint .
Please tell the reason for the same

Not sure about this behaviour.
But to avoid setting the datasource to null, use a BindingSource object to set the datasource of the DataGridView. Set the DataSource of the object as your list. And on button click, just add the item to the BindingSource object. This will add item to both the List and the DataGridView.

When I code a Setter for a property, I usually do it like this
public int SomeProperty
{
get
{
return this.someField;
}
set
{
if (this.someField != value)
{
this.someField = value;
this.Invalidate();
}
}
}
and this is probably what is happening in your case. Setting a field to the value that it already holds, results in nothing actually happening.
To solve your problem you really need to use the more complex version of DataBinding which includes change management. So that changes you make to objSapient are automatically reflected by the binding.
Take a look at the documentation for BindingSource, or Google for complex databinding to objects (or similar)

Your explanation made absolutely no sense what-so-ever.
|

Hi Vinay,
With this minimum explanation, it seems that you are using data binding. Also, you have some ListControl in your form as well which is related to the same datasource (i.e. same datatable might be used for Grid and that control). This list control does not have blank value in its master data.
Verify this one otherwise try to debug (setting break points whereever ValueMember is set) your code to find out where you are getting the error.

I am having two comboboxcontrol on Winform2008, whenever I am selecting value from one combo , then same text is coming in second combo, but just I want to separation in both ..
Vinay

Use different datasource for each combobox, even if the data are the same.
|
|
|
|
|
|
So are you saying that each combo should point to a different copy of the save data? Isn't that a little inefficient??
|
|
|
|
|
All you need to do is create two BindingSource objects and put them between the Combo's and the data. Each Combo will have its DataSource property set to one of the BindingSource objects. Then each BindingSource will have it's DataSource property point to the same data object. Something like this:
ComboBox1.DataSource ------> BindingSource1 -----\
\
+----> Data
/
ComboBox2.DataSource ------> BindingSource2 -----/
|
|
|
|
|
See that's why I skulk around here, I have used the table.copy method to achieve this in the past as I have never used a bindingsource as a datasource for a combo.
Thanks Dave

Set/check the text of the button in the onclick event.

Not enough information to answer your question. The biggest problem with this design is how is the button click handler going to know the difference in the users intent when the button is clicked??
