I have a simple issue..the user types his/her name in a textbox. Accidentally if a space is entered after a name or before, is it possible for me to trim it while accepting and not raise any error (which actually arises when the textbox is empty)?

View 4 RepliesI'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.
View 8 RepliesI've updated a number of production sites from 3.5 to 4.0 and have found a really annoying problem where it will insert a blank space into Multi-Line text boxes
The tag is entered as....
<asp:TextBox
ID="AdvDayNotesTB"
runat="server"
TextMode="MultiLine"
CssClass="text"
Width="99%"></asp:TextBox>
<asp:TextBox
ID="AdvDayNotesTB"
runat="server"
TextMode="MultiLine"
CssClass="text"
Width="99%"

The HTML is rendered as...
<TEXTAREA style="WIDTH: 99%" id="ctl00_C_FV1_AdvDayNotesTB" rows="1" cols="20">
Is there any built in option to avoid users to register with a username that has blank spaces in it? For example "John Smith". Or I have to check it with a validator?I'm using the createuserwizard.

how do you handle null data on gridview? and also the white spaces, it seems that the white spaces are converting to " "
Note: i can't replace the because i have 1 column thats in html form.
I am doing project in .NET3.5(asp.net with c#.net) and Sqlserver2005.
I want to get Text as it is inputted from textbox with new lines and spaces from DB.
means do i change the datatypes in DB or should i store data in any textfile.
and also if put Richtextbox control as it is text also i should get as output in label.
and how to use rich textbox control.
like our asp.net forum witepost and getting post function.
Whenever I enter data in a text box, such as two words with many spaces in between, on postback .Net appears to automatically replace the many spaces with one space. I want the data to be exactly as it is entered in the text box.
textbox: word1 word2
postback result: word1 word2
desired result: word1 word2
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.

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.
I set my textbox1 to equal a responsetext string and when I click into the textbox and then click the end key there are spaces or blank space at the end. I need to get reid of them. I tried the following, but no luck:
textbox1.text = responseText.TrimEnd(" ")
In my asp web page, there is a multiline textbox. And upon a button click from the same page I need to delete the last row or line from the multiline textbox. How is that possible.

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>

Why this is not working...
In my asp.net+vb web I was using this code to change row colour of gridview
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
If e.Row.DataItem("bloodgp") Is System.DBNull.Value <> True AndAlso e.Row.DataItem("bloodgp") Then
e.Row.BackColor = Drawing.Color.LightGreen
End If
End If
End Sub
Now I want to change the cell backcolour to red for those cells are blank ....
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.
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();
}
}
