I have a table in the db with one column containing a URL like http://site.com/users/*/profile.I am given a URL (like http://site.com/users/234/profile) and want to select all the rows in the db that match the url (in this case * is a wildcard).
I was thinking of using Regex to do this, by replacing the * with regex for any character. But am unsure as to what the SQL or LINQ code should be for the selection.
I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system.I'm using the following Regex:
"([0-9]{1,3}\.|\*\.){3}([0-9]{1,3}|\*){1}"
Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator.Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ?
Is there a way to do a
"select * as"
and rename all columns with some prefix, rather than having to name columns individually? Or better yet, when doing a join and getting all columns from both tables, how do you identify them uniquely in the VB where some columns have the same name?
I have a Dropdownlist filled from database. Its datavaluefield has a combination of 2 values from database as :
Select (convert(varchar,DoctorID)+'*'+Ltrim(RTrim(DoctorAddress))) as DoctorIDAddress
ddlDoctorName.DataValueField = "DoctorIDAddress"
now while updating the form i want to select value in dropdown list with a combination of two values from database table.
ddlDoctorName.SelectedValue = Securities.HTMLEncode(dr("ReferredByDoctorID").ToString()) + "*" + Securities.HTMLEncode(dr("RefAddress").ToString.Trim)
but when i HTMLCode my Address field and it has '&' saved in it, then it encodes it as '&' and ddl don't have selected value.
so , is there any way to select an item value from ddl using like operator or other :
ddlDoctorName.SelectedValue = Securities.HTMLEncode(dr("ReferredByDoctorID").ToString()) + "*" +"%"
I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)
View 1 RepliesI have a gridview which right now is getting loaded with four pages of data. There are 50 rows per page. My problem is I need the "select all" button on my page to select 180 rows, not just the 50 on the page. This is my javascript:
Code:
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
for (var i = 0; i < frm.elements.length; i++) {
var e = frm.elements[i];
if (e.type == 'checkbox' && e.name.indexOf("ckSelected") > -1)
e.checked = isSelected;
}
}
I am more a C# person than javascript, but I am deducing that I need something other than document.forms[0] to represent the entire gridview. Or perhaps, I can't do this in javascript at all. Do I need server code to run and set a session variable, then when the user clicks the button to do something with all his selected rows (it goes to a detail page), query that session variable to see if it's all rows instead of iterating through each gridview row individually to see if the checkbox is checked?
