Asp.net - Javascript Validation - Comparing 2 Text Box Values

Jun 11, 2010

I have a table with 5 rows and 2 columns. Each cell contains a text box. I want to show error if one of the text boxes in each column is empty. I want both text boxes in a row shld be filled or both shld empty. How can i do this via Asp.net validation controls? I want to extend CompareValidator so that it will validate only if the controlToValidate and controlToCompare both have some text in it or both are empty.

Forms Data Controls :: Row Data Bound Method That Inserts A Row When Comparing Values On A Particular Field

Jan 22, 2010

I have a gridview, which on the row data bound method that inserts a row when comparing values on a particular field. If the two values are different, a new row is inserted, if not no row is inserted. This coding is working as a grouping gridview, and is working correctly. However, I have problem, and problem is counting the rows between each group, which I want to display in my blank row between each group, the value of which I am holding in a hiddenfield.

When I try to do it, the first group doesn't show the result, but is displayed on the next group. I am pretty sure that I am doing something wrong. My approach is that if the value between the last row and the existing row are different, then the value is one, on the next row data bound event, if the values are the same then the value is increased by one, else the value is one because it is a new group. Here is my code:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Table tbl = e.Row.Parent as Table;
TableCell cell = new TableCell();
CheckBox chk = new CheckBox();
Label lbl2 = new Label();
HiddenField rowValue = new HiddenField();
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Visible = false;
}
else
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Session["count"] = 1;
Label lbl = (Label)e.Row.FindControl("lblValue");
string str1 = ((Label)(lbl)).Text;
string prevStr= (string)Session["previousStr"];
if (prevStr== str1)
{
lbl.Visible = false;...................

Regex Validation On A Text Box Locks-up Text Box On Postback?

Nov 10, 2010

I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I'm trying to use required validation controls on two text boxes and tried using the following code:

<asp:TextBox ID="starttimeInput" runat="server" Width="130px" Height="23px"></asp:TextBox>
<span class="style1">*</span> Start Time <asp:RequiredFieldValidator ValidationExpression="^([1-9]|1[0-2]|0[1-9]){1}(:[0-5][0-9][aApP][mM]){1}$"
ID="StartTimeValidator" runat="server"
ErrorMessage="You Must Supply Both a Start and an End Time"
ControlToValidate="starttimeInput"></asp:RequiredFieldValidator>

but I can still enter whatever I want into the text box. What I'm trying to check for is that users are entering a time in a valid format.
