Conditional Formatting

[Kristof]

Hi,

I have a gridview with data, similar to your example gridview on conditional formatting. I copy / pasted the example code for conditional formatting but I don't get it to work properly.
The problem is that there is no initial formatting. The gridview has it's standard look. Only after clicking on a cell that contains the formatting-conditional text, the row gets the correct color. Your example seems to work fine, but I see no differences between that code and mine.

 

radGridView1.CellFormatting += new CellFormattingEventHandler(radGridView1_CellFormatting);
radGridView1.DataSource = meterObjectValueList;
radGridView1.Refresh();

GridViewColumn col = radGridView1.MasterGridViewTemplate.Columns.FindByDataField("State");
ConditionalFormattingObject c1 = new ConditionalFormattingObject("ValueRead", ConditionTypes.Equal, "read", "", true);
c1.RowBackColor = Color.Green;
c1.RowForeColor = Color.Black;
col.ConditionalFormattingObjectList.Add(c1);
ConditionalFormattingObject c2 = new ConditionalFormattingObject("ValueInit", ConditionTypes.Equal, "init", "", true);
c2.RowBackColor = Color.Blue;
col.ConditionalFormattingObjectList.Add(c2);
radGridView1.MasterGridViewInfo.UpdateView();
radGridView1.Refresh();

 
Am I missing something?

Ben.

Hi Kristof,

Thank you for bringing this issue to our attention.

I copy-pasted your code into a sample project and ran it, but I could not reproduce the problem. I think the problem might be coming from the handler of the CellFormatting event, but I do not have this piece of the puzzle.

Could you send me a sample project which reproduces the problem you're experiencing, or alternatively, the code in the CellFormatting handler? You can do so in a support ticket.

Thanks in advance.
 

Kind regards,

Thanks for thinking with me!

I found the cause of the problem: the column I use for formatting is displaying enum values. If I use a different column with real string values bound to it, then it actually works.

So, to reproduce the problem, simply add an enum to the datasource and bind it to a column and then try conditional formatting.

Probably the check "IsEqual" doesn't return a match when checking against enums. This could be solved by checking against the enum.ToString();

Cheers,

Ben

p.s. happy holidays

Hi, Looks like this problem still exist in 2008.1.619 version of RadControls for winforms.

I'm applying conditional formatiiing on enum column and it does not work.

Hi Leadeng Leadeng,

Thank you for writing.

I could not reproduce the issue you are describing. I created a DataTable with two columns, one of them of type int, and the other one of type MyFlag, defined as follows:

    public enum MyFlag
    {
        On = 0,
        Off = 1,
        Indeterminate = 2
    }

This table was then bound to the grid.

Immediately after the databinding, two conditional formatting objects were created and added to the grid as shown in the code below:

            ConditionalFormattingObject c1 = new ConditionalFormattingObject();
            c1.CellBackColor = Color.Red;
            c1.ApplyToRow = true;
            c1.ConditionType = ConditionTypes.Equal;
            c1.TValue1 = "1";
            c1.Name = "red";

            ConditionalFormattingObject c2 = new ConditionalFormattingObject();
            c2.CellBackColor = Color.Blue;
            c2.ApplyToRow = true;
            c2.ConditionType = ConditionTypes.Equal;
            c2.TValue1 = "2";
            c2.Name = "blue";

            radGridView1.MasterGridViewTemplate.Columns[1].ConditionalFormattingObjectList.Add(c1);
            radGridView1.MasterGridViewTemplate.Columns[1].ConditionalFormattingObjectList.Add(c2);

Please replicate the scenario that I tested, and let me know if you experience any issues. Furthermore, do not hesitate to contact us with any other questions you have.

All the best,
