Custom Validation inside Repeater

RaviKalyanK

I have to validate SSN which will be entered in 3 different textboxes (txtSSN1, txtSSN2, txtSSN3). 1. If SSN1 is entered and other TWO textboxes are left blank, then CustomValidater should raise an error. 2. If all 3 textboxes are blank, then is a valid scenario. return true and save. 3. If all 3 textboxes are entered with values, return true. As I have these controls in a Repeater, I cann't able to find the controls from clientside. Need help

You can validate on OnItemDataBound event of repeater.

What is the problem with that. Repeater actually places the same html that you define in ItemTemplate and AlternateItemTemplate. You can easily use OnItemDataBound event to find the controls. Inside it write like this: if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternateItem) { TextBox tb = e.Item.FindControl("yourserversideiD"); tb.Attributes.Add("onblur", yourjavascript); } Like this way you can easily find any serverside control inside Repeater and apply your javascript. so try this out.. :rose:

Guys, Thanks for the reply. All I need is a client side validation. Server side is just a matter of 20min for me... I'm looking for a client side validation. Thanks

Hey Ravi... Believe me.. I was really talking about client side validation in the code above. onblur is a client side event, I think. Just place your javascript there. Call the validation javascript from there. if you pass like this : txt.Attributes.Add("onblur", "javascript:func(this)") you will get the txtbox on the function. Also you might use txt.ClientId to pass the id. :)

My requirement is to validate the SSN in Save_Click event. NOT in "Onblur" event. I also have "Add Child" button using which I'm adding new Repeater.. So I can add N number of children before clicking on save button. And each repeater is having SSN1, SSN2 and SSN3 textboxes that I need to validate. Thanks for the replies. Ravi

Ok.. so for each SSN1, SSN2 and SSN3 you will be having one button.. So do like this :

Button btn = e.Item.FindControl("yourbuttonid");
TextBox SSN1 = e.Item.FindControl("SSN1ID");
TextBox SSN2 = e.Item.FindControl("SSN2ID");
TextBox SSN3 = e.Item.FindControl("SSN3ID");
string script = "javascript:validate('" + SSN1.ClientId + "','" + SSN2.ClientId + "','" + SSN3.ClientId + "');";
btn.Attributes.Add("onclick", script);

Now in the page designer, place a script tag and add a function validate:

function validate(ssn1id, ssn2id, ssn3id){
var ssn1 = document.getElementById(ssn1id);
var ssn2 = document.getElementById(ssn2id);
var ssn3 = document.getElementById(ssn3id);

// do the logic here.

}

I home this is what you wanted. :thumbsup:
