Web Forms :: Blank Spaces After Zip And Why Do They Causes?

May 3, 2010

I've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.

SQL Reporting :: Adding White Spaces To A TextBox In A Rdlc?

Jan 28, 2011

I am attempting to concatenate white spaces to a field value in a rdlc report.

I am using the following formula in the TextBox but it does not work as I'd like it to.

[Code]....

I have a feeling it's because it generates HTML, but I can not figure out any other way to do this. I have also attempted to simply enter an empty string (" " & field) as well as chr(10) (empty character), but these were also failures.

Also, I tested the comparisons, by manually entering fake data if the condition is met and this worked fine, so it is not the comparisons.

C# - MVC - Blank Model Not Returning Blank Data

Jun 2, 2010

I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.

[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}

So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.

Blank Gridview Cell Populates "&nbsp" Into Textbox?

Nov 6, 2010

I've noticed that when i populate textboxes from a selected row in a gridview that if the field is blank it displays " " in the textbox.

Here is the solution I came up with. I check each cell before adding it to the textbox.

I get the feeling that I'm either doing something wrong to have this problem in the first place or that there is a better way to handle this.

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
//// Get the currently selected row using the SelectedRow property.
GridViewRow row = GridView1.SelectedRow;
// Load data from selected row into textboxes
if (row.Cells[1].Text.Trim() != " ")
{
txtEditCust_ID.Text = row.Cells[1].Text.Trim();
}
}

Web Forms :: Password And Confirm Password Validation - Simple Alert Of Blank Textbox Is Not Working

May 7, 2015

I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:

Javascript code:- 

<script type="text/javascript">
function ltrim(str) {
var reg
reg = /^s+/g
return str.replace(reg, "")
}
function rtrim(str) {

[Code] .....

aspx code:-

<tr>
<td class="auto-style1">Old Password</td>
<td class="auto-style2">
<asp:TextBox ID="txtOldPassword" runat="server" TextMode="Password" class="txtcareer"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqtxtOldPassword" ControlToValidate="txtOldPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

[Code] ...

Why this is not working...
