hi
i added a combobox and dateTimePicker in datagrid columns.These controls are working properly.But whenever any value is selected from these controls, the datagrid is not get edited.i mean that no new row is added to datagrid,hence the datagrid is appearing with one row only.There are 3 columns in datagrid two with comboboxes and one DateTimePicker.
how to solve this problem?
here is the code i had written
sFromCb=new ComboBox();<br />
sFromCb.Cursor = System.Windows.Forms.Cursors.Arrow;<br />
sFromCb.DropDownStyle = ComboBoxStyle.DropDownList;<br />
sFromCb.Width = 100;<br />
sFromCb.SelectionChangeCommitted +=new EventHandler(sFromCb_SelectionChangeCommitted);<br />
<br />
DataGridTextBoxColumn fromcol=new DataGridTextBoxColumn();<br />
fromcol.MappingName = dtCore.Columns[i].ColumnName; <br />
fromcol.HeaderText = fromcol.MappingName;<br />
fromcol.Width=100;<br />
fromcol.ReadOnly=true;<br />
fromcol.TextBox.Enter +=new EventHandler(fromcolTextBox_Enter);<br />
fromcol.TextBox.Leave +=new EventHandler(fromcolTextBox_Leave);<br />
fromcol.TextBox.Controls.Add(sFromCb);<br />
tableStyle.GridColumnStyles.Add(fromcol);<br />
<br />
private void sFromCb_SelectionChangeCommitted(object sender, EventArgs e)<br />
{<br />
dataGrid1[dataGrid1.CurrentCell] = ((ComboBox)sender).SelectedItem.ToString(); }<br />
<br />
private void fromcolTextBox_Enter(object sender, EventArgs e)<br />
{<br />
((TextBox)sender).Visible=true;<br />
sFromCb.SelectedItem=((TextBox)sender).Text;<br />
sFromCb.Focus();<br />
}<br />
private void fromcolTextBox_Leave(object sender, EventArgs e)<br />
{<br />
((TextBox)sender).Text=dataGrid1[dataGrid1.CurrentCell].ToString();<br />
((TextBox)sender).Visible=false;<br />
}The items in combobox is coming from a dataset.
Thanks in advance for help

Submit to where?
Changes are always written to the DataSource, but that doesn't mean that they are written to the database or file that the data comes from. That you have to write code for. If this is what you want to do you must be more specific on what the source is. There is also a lot of examples on how to do this on MSDN and internet.

easy, switch off the computer, unplug it, pack it back into the box it came in, take it back to the store and tell them you're not allowed to own a computer.
Or, read this[^] and pay attention to the section on error messages.

Hi all,
I have a form and there is a combobox on it. I pass some values to a function in another class for example:
...
public void ODBCBindControls(Control.ControlCollection collection, BindingSource source)
...
I then want to set the DataSource and the DisplayMember of the combobox in the function mentioned above collection[x]. But I cannot get hold of the two properties. Why is this? Is there a way around it, or am I trying something that is desirable?
Many thanks in advance

Well this works ...
...
ComboBox box = (ComboBox)collection[c];
box.DataSource = source;
box.DisplayMember = "COID";

You always need to cast the object to the correct type to be able to access specific properties. So this way is the only way.
|
|

|

Thanks for the advice Christian.
I do something like this:
...
Type controlType = collection[c].GetType();
switch (controlType.FullName)
{
case "System.Windows.Forms.ComboBox":
...
}
...
Thanks

Or...
if (collection[c] is System.Windows.Forms.ComboBox)
{

In C# , I have upload data from CSv file to SQL Table without using CsvDataReader. is there a way to do this?
|
|
|
|
|
Why can't you use CsvDataReader? One alternative would be a combination of StreamReader and the String.Split method.

hi
What is the way to check for empty arraylist?..any one can help me ?
|
|
|
|
|
Check the .Count property.
|
|
|
|
|
yaa...i tried...but it is throwing an exception....
|
|
|
|
|
Probably your ArrayList is not created yet. Check if it's null first. Not created is not the same as empty.
|
|
|
|
|
In that case show your code and tell us what the exception says.

I am developing an windows application where i have an MDI parent form that has menu strip i want that what ever option i have select from menu strip that may effect on MDI child form.
Suppose that
I have a label control on the child form i what to change the text color of that label then i have selected the option from menustrip that is in MDIparent so how can i show color dialog from MDI parent that can work for MDI Child form...
|
|
|
|
|
I would accomplish this with events. Create events for all toolbar buttons on the MDI parent and have the child forms listen to the events that they can make something out of. That way you do not need to check if the currently active child form can handle the function that the user is clicking.

1 - everyone wants help, 'help' is not an intelligent subject
2 - yes, we can help. What's the problem ? Oh, the problem is that you have a bunch of blank methods and hope we'll do your homework for you ? In that case, no.
