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.
im rather new to this and unsure of how to complete the task in the title. I currently have a text box called txtmodule, i want to restict the user from entering any number except 20 or 40. How can i do this using a RegularExpressionValidator or is there a better way?
I have records that have an initial value of 'blue' and stay 'blue' until after 2 days then they turn to 'green', Turn 'orange' after 15 days and then after 20 days turn 'red'.The results will be pulled into a gridview.What I'm having difficulty is; what's the best way of calculating the days, in sql server or in c#?Trying to get construct date examples is proving to be a bit of a pain:

has anyone done something similar and found a good way of doing this?
I would like to multiply the values from two text boxes (txtBox1 should contain an Integer value, txtBox2 should contain a Float value) and place the result in a third text box. My code is below, but it doesn't work. The javascript function is called, otherwise it fails.
I have a problem that I have to enter float values in my database from a textbox. The problem is I want to enter only float values upto two decimal places(like 12.34, 56.78, etc). How do I do this.? Do I need to first convert the values from my textbox (string values) to Int64 before submitting?
My second problem is that I have to compare that float value in my database to a value in another text box. I am using this sort of code:
I'm pretty sure this is in the wrong forum category, but I couldn't find a relevant category, so here goes!'m looking for a way of highlighting text changes between two sets of content, very similar to how this website's wiki works:For example, if I go to an edit page on the wiki, I can compare two versions and see the difference:[URL]
I am trying to compare a login textbox password and username with a custom validator using linq to get information from the database it always returns false though on the validator where my code below is going wrong.
protected void LoginValidate(object source, ServerValidateEventArgs args) { TiamoDataContext context = new TiamoDataContext(); var UsernameCheck = from User in context.Users where User.Username == TextBoxLoginUsername.Text && User.Password ==

I dont know where I am going wrong I know its most probably some sort of silly mistake and me being inexperienced at this...
I am using one datalist control for uploading multiple images.I hv used one Asp:FileUplaod Control and one button in one itemtemplate.I am using reqired field validator and regular expression validator for file upload cntrl I am assigning validation group for both of them on ItemDataBound event of my datalist so that each upload cntrl hv same validaton group as required field and regular expression validator.Now what i want to do is - i want to show my error message in validation summary which is right at the top of the page.I want one know how to write javascript that will assign validation group of my control in datalist on which i click ?
I have a stored procedure, which I'm calling from ASP.Net application. I'm facing a problem in stored procedure when comparing values.Please check code below to get further details.
Stored Procedure: ALTER PROCEDURE [dbo].[MyStoredProcedure] (@ItemID nvarchar(50), @Weight1 float, @Weight2 float) -- check remaining/available weight in items table DECLARE @RemainingWeight float SET @RemainingWeight = (SELECT RemainingWeight FROM items WHERE ItemID = @ItemID) [code]...
I am dealing with dynamic fields in a for loop and now I need to retrieve the values that are being typed in the dynamic fields, any idea how can I do that? 2)also when I click the submit button, upon postback, the dynamic fields have gone missing, have been trying to slove that, but i did not, anyone knows how to deal with this? kinda urgent :x
3) and How do you compare the 2 dynamic fields? For eg: Im comparing the tbSch[i] to tbSch[i], so that the dates cannot be the same, am using a compare validator, but it throws me error that im comparing the same fields :) even though i change to ("tbSch" + i) for both, sorry Will provide my code snippet as follow :D tbNum is a textbox where user enter numbers and click generate
protected void btnGen_Click(object sender, EventArgs e) { for (int i = 0; i < Convert.ToInt32(tbNum.Text); i++) { // label and textbox needed Label lblSch = new Label(); TextBox tbSch = new TextBox(); Label lblWsGrp = new Label(); DropDownList ddlWsGrp = new DropDownList(); CompareValidator cvSame = new CompareValidator(); cvSame.ID = "cvSame" + i; cvSame.ErrorMessage = "Date cannot be the same"; cvSame.Operator = ValidationCompareOperator.NotEqual; cvSame.Type = ValidationDataType.Date; cvSame.Display = ValidatorDisplay.Dynamic; cvSame.EnableViewState = true; cvSame.ControlToValidate = (tbSch.ID);<<<<< what should be the value in here? cvSame.ControlToCompare = (tbSch.ID);<<<<<<<<<< and here? //schdule date lblSch.ID = "lblSch" + i; lblSch.Text = "Session Date : "; lblSch.EnableViewState = true; tbSch.ID = "tbSch" + i; tbSch.Width = 210; tbSch.Height = 27; tbSch.EnableViewState = true; //workshop grp lblWsGrp.ID = "lblwsgrp" + i; lblWsGrp.Text = "Workshop Group : "; lblWsGrp.EnableViewState = true; ddlWsGrp.ID = "ddlWsGrp" + i; ddlWsGrp.Height = 27; ddlWsGrp.Width = 210; ddlWsGrp.EnableViewState = true; ddlWsGrp.Items.Add("1"); ddlWsGrp.Items.Add("2"); //table to store data TableRow trow = new TableRow(); TableRow trow2 = new TableRow(); //row1 TableCell tc1 = new TableCell(); TableCell tc2 = new TableCell(); TableCell tc3 = new TableCell(); TableCell tc4 = new TableCell(); //row2 TableCell tc5 = new TableCell(); TableCell tc6 = new TableCell(); TableCell tc7 = new TableCell(); TableCell tc8 = new TableCell(); TableCelltc9 = new TableCell(); tc1.Controls.Add(lblSch); tc2.Controls.Add(tbSch); tc3.Controls.Add(lblWsGrp); tc4.Controls.Add(ddlWsGrp); tc5.Controls.Add(space); tc6.Controls.Add(CeSess); tc7.Controls.Add(space); tc8.Controls.Add(space); tc9.Controls.Add(cvSame) trow.Cells.Add(tc1); trow.Cells.Add(tc2); trow.Cells.Add(tc3); trow.Cells.Add(tc4); trow2.Cells.Add(tc5); trow2.Cells.Add(tc6); trow2.Cells.Add(tc7); trow2.Cells.Add(tc8); trow2.Cells.Add(t9); this.table3.Rows.Add(trow); this.table3.Rows.Add(trow2); } }
I have a form that contains a text box called "MyDate" in which the user enters a date. I have a table that contains records of which one of the fields in the record is a date field named "DateAvailable" (type is "datetime"). I want to compare the data in the text box to the "DateAvailable" field in record. How do I define my text box as a "datetime" field.
I am getting int values from the stored procedure. But when i bind this datasource with the gridview i am seeing the values being converted into float. i am using Text='<% # Bind("Quantity") %' I wanna that to be displayed as int, with out zero'seg: let the value be 233, when i bind that its getting displayed as 233.00
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;...................
How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.
i've currently got a registration form that works fully however i've run into a problem getting the validation text to appear. basically i want the form to present the following message "Congrats you are now registered and can login using the login page" only if all the fields in it are filled in. However with what i have coded below it always presents the message, i am using asp.net 2.0 with webmatrix.
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?
Is there a way in .net to display the text automatically when i type the first letter or word in a text box? I am looking for something like MS-Excel.. In MS-Excel, if the first word is given, automatically it displays the remaining texts, only if values are given previously.
want to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
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.
