View 1 RepliesHow do I go about adding a ButtonColumn to a DataTable.
I am basically using a DataTable as the DataSource of a DataGrid and need to add a ButtonColumn to the DataTable so that when I DataBind it to the DataGrid it all works.
Although when I try
dt.Columns.Add(buttonColumn)
This is not allowed. It has to be a basic DataColumn.
i have a dataset and a table into named Students. Students(StudentName, age)
i wanna name colunm to string array. but not use loops (for foreach..). is there any way?
string[] array = this.dataSetZLC.Student.StudentNameColumn..
I would like to copy DataColumn from tableA to table B:
As I think it should be like this:
TableA in perdefined.
DataColumn[] dataColum = new
DataColumn[TableA .Columns.Count];
TableA .Columns.CopyTo(dataColum, 0);
DataTable TableB = new DataTable();
TableB .Columns.AddRange(dataColum);
//
=> but it raised an error at the line error, ID is belong to another table (in tableB)...
As I dont like another way:
DataTable TableB = TableA.Copy(); TableB.Clear(); // => getting structure of table A, not nice this way
I have some code that splits a session into strings by a -
My session looks something like this 123-456-789- and I split it like this
Dim MyString As String() = Session("MySession").Split("-"C)
And i've got a some code like this
Dim x as Integer
For x = 0 to MyString - 1
Response.write("Ref: " & MyString(x) & "<br>")
Next
This writes the code like this
Ref: 123
Ref: 456
Ref: 789
Ref:
So it's adding an extra Ref where it shouldn't be because there is no data after the last -
Is there a way to stop this adding in the extra one?

I am fairly new to ASP.Net and web programming in general and I am having issues trying to add values from a dropdown list in my gridview to another table.
Here is my scenario. I have 2 tables in my SQL Express DB. When editing the values of table2 in a gridview, I would like to show some data from table1 in a dropdown so users can select a value from table 1 and enter that value in table 2.
I have the Gridview setup to show table2 data.
I created a field template and inserted my dropdown list and linked it to my table1 data source.
When I run my web form, I can click to edit one of the fields in the gridview, and my dropdown list correctly displays the data from table 1, but when I try to update the table2 with the dropdown value, it doesn't correctly update. The row in table2 never updates.
posting the dropdown value from table 1 into the appropriate field in table2..
Again, I am new to this and have been following the tutorials etc on this site, but can't find one pertaining to this topic.
I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN
im looking to insert an array of information into a database table
essentially what id like to do is something like this:
objCmd = New OleDb.OleDbCommand("INSERT INTO pluINFO VALUES *", objConn)
For j = 0 To 265
objCmd.Parameters.Add( info(j) )
Next
this code gives me a syntax error for the insert statement
is there anyway i can set the insert statement that would allow me to add each element of the array(looping through rather than hardcoding several hundred entries) into the table?
I used Autocomplete Without using web Method(ajax call). But I want get data for textbox from database. How I can this?
View 1 RepliesI have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
I need to pass many records with number of fields(i.e 5rows and 5 columns) in either array or table form to oracle for processing. Is it possible to pass array/table from asp.net pages? If no, any solutions for this? I have been thinking of passing it as string concatenated with delimiter and split it. Seems like it is not appropriate as i have to pass 5 strings(5rows)
View 2 RepliesI would like to split the string to the string array.
but when the string hasn't has the splite sperator, i can't put the string into string array directly.
how to do?

str_array=Str.Split(',');
}
else
{
str_array=Str; <-- error occurs at this line.
