Tab Strip - Validate Multiple Tabs Individually

[Josh Pollard]

I want to be able to validate all of the controls in all of the tabs in one button click event. I have all of the controls broken out into separate validation groups by their tab. The tricky part is that i want to know what tab has the invalid controls.

I tried creating an array of my validation groups in the same order as the tabs and then looping through it like so:

for (int i = 0; i < ValidationGroups.Count - 1; i++)

            {

                Page.Validate(ValidationGroups[i]);

                if (!Page.IsValid)

                    RadTabStrip1.Tabs[i].ImageUrl = iconPath;

            }

The problem is that Page.IsValid will always return false as soon as ANY validation group is false. So if I have invalid controls on the first tab, the Page.IsValid will always return false for every tab after that.

Does anyone have a better solution? Thanks!

Thank you. I also found another way to do it.

I added this function:

        protected bool IsGroupValid(string ValidationGroup)
        {
            foreach (BaseValidator validator in Page.Validators)
            {
                if (validator.ValidationGroup == ValidationGroup)
                {
                    bool fValid = validator.IsValid;
                    if (fValid)
                    {
                        validator.Validate();
                        fValid = validator.IsValid;
                    }
                    if (!fValid)
                        return false;
                }

            }
            return true;
        }

And then changed my earlier code to this:

            for (int i = 0; i < ValidationGroups.Count - 1; i++)
            {
                if (IsGroupValid(ValidationGroups[i]) == false)
                    RadTabStrip1.Tabs[i].ImageUrl = iconPath;
            }

This puts the image stored in the iconPath variable on all of the tabs with invalid controls and fires the validation for each of those controls.
