How can I replace empty space in textbox with a dash (-) before form values are inserted?
[Code]....
I also tried using the datasource's Inserting method but neither works.
I have string. There are no items to show in this view of the "Personal Documents" then assign to string str variable string str ="There are no items to show in this view of the "Personal Documents" library" Now planning to replace "" and make it to actual string to str object. I tried below, but did not worked
str = str.Replace(@"",string.Empty);
I want str value should be string str ="There are no items to show in this view of the "Personal Documents" library" I need to find this string in another string. While searching into that string. I couldn't found because str contains "".
If I have JSON like this and pass it to the engine I am using to create a PDF file, the word "null" appears on the PDF. This isn't really my example, but I googled "json replace null empty string" and this was a hit, which is a good representation of my data, also:
{
"relationship": {
"type": "relationship",
"id": null,
"followed_id": null
}
}
We use a rendering engine that creates a PDF from a fixed template and variable data in the form of a json string. But our customers don't want to read that the id is "null", they want to read that the id is blank. In my C# program, the json is just a string, so I can easily do something like this:
jsonString = jsonString.Replace("null,", ",");but the issue is I can't replace null-comma with a comma, because then it's invalid json.
how to I make the rendering engine *and* my customer both happy?
I have this code, how will I write the code so I can check if a textbox i empty? This way want work. Now it goes in if cellPhone != null all the time.

In FormView (insert) I have a number of textboxes into which number will be inputted. I need all these textboxes to add up and display the total in a Label which I can then insert into the database with all the individual values. I expected this to be a simple thing... Then it appears that the best way to do this is to use javascript, which I have never used! SO this is my attempt which is a combination of things I found on the net, In the head (Clientapp is the name of my form)
<script type="text/javascript" language="javascript">
function Add1(Clientapp) {
var a, b, c;
a = document.Clientapp.BondRepaymentTextBox.Value;
b = document.Clientapp.PropertyRentalTextBox.Value;
c = eval(a) + eval(b);
document.Clientapp.ceTotalTextBox.Value = c;
}
</script>
Code behind on Page Load
PropertyRentalTextBox.Attributes["onchange"] = "javascript: Changed( this );";
I'm using this:

Is there a better way to do it?
This is completely frustrating and probably embarrassing as well. A while back I posted a similar question and resolved the issue. [URL]...scope_identity The program has been working ever since, until yesterday when as it turns out SCOPE_IDENTITY() started returning an empty string even though a record is being inserted. I am not sure what has changed since the fateful day.
[Code]...
I am hoping that there is something I am just not seeing here. A lot of the information I have seen thus far indicates that there are problems with SCOPE_IDENTITY() but most of those are related to inserting multiple records. As you can see this should be fairly straight forward. The thing that really has got my goat is that it used to work and now it doesn't. If someone could take a look at the above code and comment on any anomalies it would be great. Also I have heard suggestions for switching to ADO.NET and it is beginning to look a lot more attractive every day. But I have a ways to go before making the switch so it is SqlDataSources for now

When I click submit I get a message that I cannot insert a Null into the field IntershipNumAvailable. This makes sense since I made this field a required field in the database.
How do I get the form to recognize that the user selected item is the one I want to write to the database?
What changes do I need to make here? Do I need to make changes to my parameter list?
I need to replace <span> entries in a string to legacy html code because it's going to be used in a report for Crystal Reports. <b> works with Crystal, but the<span>'s do not.
Here's the string which I'm trying to replace: <span style="font-weight: bold">%THIS CAN BE ANY TEXT%</span>. I want to replace it to
<b>%THIS CAN BE ANY TEXT%</b>.

I'm stuck getting a value from a textbox in code behind. I have tried
Code:

string s1 = Server.HtmlEncode(txtEmployeeNr.Text);
And just get an empty string.
I have used the last one before with good results.
I am building a Web Content form in which the user enters some data in asp:TextBoxes, and presses submit to store the data in the database.
I am using an Upadate Panel, in which I have put the afore mentioned asp:TextBoxes. Is there a way to set TextBox.Text = string.Empty after the submit?
Note that I have implemented code, which sets my TextBox.Text = string.Empty in my aspx.cs file, which of course does not work since I am using the update panel with an AsyncPostBackTrigger...
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes.

But i want a solution while maintaining the bound fields ,if any.
View 2 RepliesIn my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?

I have a FormView with a byte field. The field is not required and if I don't enter a value, I get an error that the value is not acceptable in a byte field. I can replace the null value with 0 but I would prefer not to.
What is the best way to handle this so that if I do not enter a value in a byte (or int16) field to insert a null value (or whatever they do in the ASP.net).
I am getting taggings like the following in a string
<color> vocation </color>
<color> elation </color>
<color> sage </color>
you can notice that each tagging differs only in the wordings
vocation
elation
sage
But i want to write a code some thing like this
Regex.Replace(userAx, "<color> vocation </color>",
"<color> </color>"
so that the resulting output does not contain words at the centre.In the above code instead of giving the word vocation exclusively, i have to mention some pattern, so that it will replace all the words instead of doing it for first sentence only.How to modify my code?

View 2 RepliesI should probably post this question to a different forum but I've had such good luck on this one, I hate to leave...I have an SQLDataSource which has a concatenated field of FirstName + ' " + LastName AS FullName. That datasource is used to populate a Primary Contact combobox in the GridView based on the dsOrganizations datasource. ComboBox datasource = dsContacts, TextField = FullName, ValueField = ContactID, ValueType = Int32
nfortunately, not all the Organizations have Primary Contacts listed yet so the above substitution breaks and doesn't even show the Primary Contacts when they existWhat I need is someway to either leave the Primary Contact row blank in the DataGrid or replace it with "[none selected]"
