i can add a BooleanRender to a column to get checkboxes to appear but how do you actually control it's value or react to someone clicking on the data?
the data is connected to a StringsData object
examples for the grid control are very limited so far. I'm trying to migrate a datagrid control assing the TeeGrid would be faster to render but so far I've spent multiple hours and not got very far with porting the functionality I use on the datagrid at the moment

Hello,
I'm afraid this is a bug which I have added to our issue tracker with
id=2109 but which we have already fixed. This fix will become available very shortly.
The issue can best be seen with reference to the example under:
https://github.com/Steema/TeeGrid-for-. ... %20Heights
and with the following modifications:
Code: Select all
//tmp[0, 3] = "Sample";
//tmp[0, 5] = "Hello" + Environment.NewLine + "World";
//tmp[0, 10] = "This is a long line" + Environment.NewLine + "of text with multiple" + Environment.NewLine + "lines";
tmp[0, 3] = "True";
tmp[0, 5] = "True";
tmp[0, 10] = "True";
tmp[1, 1] = "Several lines" + Environment.NewLine + "of text";
tmp[1, 6] = "More sample" + Environment.NewLine + "text";
tmp[1, 10] = "Another long line" + Environment.NewLine + "of text with multiple" + Environment.NewLine + "lines";
Steema.TeeGrid.Renders.BooleanRender bRender = new Steema.TeeGrid.Renders.BooleanRender(tTeeGrid1.Columns[0].Changed);
bRender.Changed += BRender_Changed;
tTeeGrid1.Columns[0].Render = bRender;
tTeeGrid1.Columns[1].ParentFormat = false;
tTeeGrid1.Columns[1].Format.Font.Size = 16;
tTeeGrid1.Columns[1].TextAlignment = ColumnTextAlign.Custom;
tTeeGrid1.Columns[1].TextAlign.Horizontal = HorizontalAlign.Right;
CbMultiLine_CheckedChanged(cbMultiLine, EventArgs.Empty);
//tTeeGrid1.Editing.Text.Selected = false;
}
private void button3_Click(object sender, EventArgs e)
{
MessageBox.Show(tTeeGrid1.Data.AsString(tTeeGrid1.Columns[0], 3));
}
private void BRender_Changed(object sender, EventArgs e)
{
throw new NotImplementedException();
}
note that when tTeeGrid1.Columns[0].ReadOnly is set to true the unlying data will be changed when clicking on the checkbox - you can see this by the test in button3. What will now also work is the firing of the BRender_Changed event.
