View 2 RepliesI 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 also tried using the datasource's Inserting method but neither works.
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 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]"
I have...a dynamic populated select box several input boxes a submit button form fields are loaded initially using cookies several dynamic populated divs
I want... start loading the content of my DIVs after all FORM elements have been loaded completely (= filled with data, select boxes are populated)

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 have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.

I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
View 2 RepliesI am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.

I was trying to set the alignment of elements within my web page that has some ASP.NET controls. Inside, the div tag, I need to set the alignment of Label control so that it is always right aligned in div. How can I set this?
Edit: Here's the HTML code:
<div id="UserLoggedinMessage" style="float:right; width:280px">
<div style="float:right;width:350px">
<asp:Label ID="Label3" runat="server"></asp:Label>
<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">Login now</asp:LinkButton>
<!-- Serch Box -->
<div id="WLSearchBoxDiv" style="float:right">
</div>
<!-- Seach Box -->
</div>
</div>
So, this gives me my search box and Login Button in the same line. But the Login button is left aligned. I have correct this.
I'm working with an aspx page, where once I click on a button, some calls are executed in the background and I display the returned information on the webpage. I do this by adding this information to a panel:
panel.controls.add(label)
panel.controls.add(anotherpanel)
eb user control that basically lets the user choose whether she is a registered member or unregistered member, and to fill fields accordingly, i.e., if the user is member she is asked to provide her username and password and the sign up field are being disabled. if the user is not registred then she is asked to provide registration information and the login fields are being disabled. A very common practice, I assume.
each option has its own 'ValidationGroup' on the fields. i.e. the login fields have ValidationGroup="Login", the registration fields have ValidationGroup="SignUp"
So I am new to ASP.NET MVC and I would like to create a view with a text box for each item in a collection. How do I do this, and how do I capture the information when it POSTs back?

Eventually, our team would like to move away from tables, but it seems like div tags are so much harder to use. In the above image, the layout was created using a table, but I cant figure out how to get a basic column structure working using div tags. How can I get those buttons on the same line?

View 3 RepliesCurrently, I have a list of PhoneNumber objects that I display. Here's an example of the output of the view:
[Code]....
Notice the naming of these elements: name="existing_phone[labels][6]", name="existing_phone[numbers][6], name="new_phone[labels][]", name="new_phone[numbers][].Back in the Classic ASP days, I recall being able to do something along the lines of:
[Code]....
And that would give me a 2d array of phone numbers to work with. This doesn't seem to work in .NET. Has anyone tried to do something similar that can point me in the right direction?For new phones, I should simply be able to iterate through each item and insert into the database. For existing phones, I should be able to update (or delete if the label or number are blank) records based off of the id number supplied in the array.OR..if anyone has a better, alternate solution, I'm open to something else.
