OnClientClick breaks button postback behavior

[pmourfield]

I have a RadGrid Insert/Edit Form template in which I have a Submit/Update button. This button's submit behavior works perfectly if I do not reference any JavaScript calls in it. However, upon inserting an OnClientClick, it breaks the button. Here is the ASP

<asp:Button ID="btnUpdate" Text='<%# (Container is GridEditFormInsertItem) ? "Save" : "Update" %>' runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' OnClientClick="return CheckWeight()" />

Here is the JavaScript

function CheckWeight() {
                var currentGoalWeightTotal = $("[id$='CurrentGoalWeightTotal']").val();
                var weightInput = $("[name$='AG_Weight']").val();

                if (parseInt(weightInput) + parseInt(currentGoalWeightTotal) > 100) {
                    alert("Please make sure that your goal weight total does not exceed 100.");
                    return false;
                }
            }

Eyup,

Thank you for putting this together for me. I will definitely check it out.

I was able to get my code working by making the following changes:

I changed my ASP to this:

<asp:Button ID="btnUpdate" Text='<%# (Container is GridEditFormInsertItem) ? "Save" : "Update" %>' runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' OnClientClick="if (!CheckWeight()) { return false;}" UseSubmitBehavior="false" />

And changed my JavaScript to this:

function CheckWeight() {
                var currentGoalWeightTotal = $("[id$='CurrentGoalWeightTotal']").val();
                var weightInput = $("[name$='AG_Weight']").val();

                if (parseInt(weightInput) + parseInt(currentGoalWeightTotal) > 100) {
                    alert("Please make sure that your goal weight total does not exceed 100.");
                    return false;
                } else {
                    return true;
                }
            }
