{
string s1 = "Need the first value from Command argument here";
string s2 = "Need the second value from Command argument here";
}

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);
this is how i did it....but it is not working......
$(".lbtnaddtocart", row).eq(j).attr("CommandArgument", customer.find("ProductId").text());

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 if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
View 2 RepliesI'm looking for the best design solution in relation to the following scenario:
<form>
<repeater>
<itemtemplate>
<usercontrol>
</itemtemplate>
</repeater>
submit button
</form>
The user control is a series of 5 buttons (similar to a radio button list) where only the latest button is recorded. I.e. if you click button 3 and then button 5, button 5's value is stored. The repeater can have a number of usercontrols, varying in numbers. The typical number if 5/6. When the submit button is pressed, the form needs to collect information from all user comtrols I.e. the database id of the control and the final value. The values will be processed later. At this point i'm looking at the best way of validating values, ensuring that all controls have a value and passing them onto the buttons command argument.
I have a button inside a table in gridview templatefield and i want to access its row index value in row_command event
i used this line.
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
but got error .Input string was not in a correct format.
However i am able to fetch the row index value in button _click event using this line.
Dim index As Integer = (CType(CType(sender, Control).Parent.Parent, GridViewRow)).RowIndex
i'm tryng to pass a parameter with command argument with a link button but the result i get is always "".
this is in my aspx page:
<%
LinkButton1.CommandArgument = "abcdef";
%>
<asp:LinkButton ID="LinkButton1" runat="server" OnCommand= "LinkButton1_Click">
and in my aspx.cs i have:
protected void LinkButton1_Click(object sender,CommandEventArgs ee)
{
String id = ee.CommandName.ToString();
}
the id is always "" after i press the linkbutton.
I am using ListView to display the Data.
I am getting some text or empty string from backend for a particular column.
If i got empty string i need to bind with an imageButton in that row.
and if i got a text i need to replace the imagebutton with text.

I'm trying to duplicate this link button in code behind, but I'm having problem with command & commandArgument
[code]...
First of all I don't see onclick in above code (not code behind) after rendering.
I probably have to do something different with""" linkbtn.Attributes.Add("onClick", "Imageswap")""""
What am I missing?
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)

I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

why i am getting a empty string for "GridView1.Rows[rowIndex].Cells[2].Text"?
we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?

how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...

I have a datalist which will display a list of groups from the database. In every group record, i have a button binding to it, and i give it a commandName call "joingroup" . When a user actaully clicks on the button(btnJoinGroup), the commandName fires. The problem i am facing now is, whenever i click on the button, i get this error below:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
