Gridview - Passing Multiple Argument Through CommandArgument Of Button?
Mar 5, 2010
I have a gridview with multiple rows, each has a Update button and I need to pass 2 values when someone clicks on Update button. Aside from packing the arguments inside CommandArgument separated by commas (archaic and not elegant), how would I pass more than one argument?
<asp:LinkButton ID="UpdateButton" runat="server" CommandName="UpdateRow" CommandArgument="arg_value" Text="Update and Insert" OnCommand="CommandButton_Click" ></asp:LinkButton>
As a note, the values can't be retrieved from any controls on the page, so don't offer any design solutions. Please concentrate on the question asked.

I have a TemplateField column in a gridview with a button inside of it.There is NO key value (surely that was not designed by me) , but in the other hand there aren't redundancies when comparing each single column, because they are events, and there is "starting date" and "ending date" of something that could not happen twice at the same time.I've already figured selecting with these values and all, but I just want the button to pass about five arguments to a given function.I've tested:
<asp:Button CommandArgument='<%# Eval("day")%>' ID="Button2" runat="server" Text="Button" />
And it works properly, the day of the clicked row is passed, and could be retrieved through:
e.CommandArgument.ToString();
in the GridView_RowCommand handler. How do I pass more than one argument? I've thought about concatenating with a separating character (wouldn't be that bad) but besides not knowing how to do it yet (didn't want to invest in a poor solution) I want a smarter one.

I'm using the commandArgument property of the LinkButton ( Which is wrapped inside a repeater ) to pass two values -as one string- to a second repeater then I try to split them into two values, So I could use them as parameters in my ADO.NET Code (SqlCommand Parameters)....after testing my queries don't return any results but If I passed fixed values for the parameter or change the source of the parameter (just for test from a textbox or querystring or something) I get my results, so I think the problem is in splitting.
I Conduct some arugment values from the ArgumentCommand property of the LinkButton -which is wrapped inside a repeater:
<ItemTemplate>
<asp:LinkButton id="sort_lnkbtn" Text='<%# Eval("value")%>'
CommandArgument='<%#string.Format("{0}|{1}",Eval("arrange_by_id"),Eval("value"))%>' runat="server">
</asp:LinkButton>
</ItemTemplate>
Then I receive these values and cut them into two pieces of information:
string sortByAndArrangeBy = (e.CommandArgument).ToString();
char[] separator = { '|' };
string[] sortByAndArrangeByArray = sortByAndArrangeBy.Split(separator);
Now the ado.net code uses this values as a
using (SqlConnection cn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
{
using (SqlCommand cm1 = new SqlCommand("SELECT [name] FROM brands WHERE (name like @SearchString + '%' )", cn1))
{
cm1.Parameters.Add("@SearchString", System.Data.SqlDbType.Char);
cm1.Parameters["@SearchString"].Value = sortByAndArrangeByArray[1];
cn1.Open();
using (SqlDataReader dr1 = cm1.ExecuteReader())
{
List_rpt.DataSource = dr1;
List_rpt.DataBind();
}
}
}

For a given MS SQL Database table of staff members, I'm using ASP to display each record line by line as follows:
So I've added 2 ImageButtons in an extra column and the problem I have is passing the record id as a CommandArgument to redirect to a secure page where the record can be edited or deleted.
Here's some code:
[Code]....
[Code]....
ctdRdr(0) evaluates to the ID value for the the record. )
When I click on the 'Delete' ImageButton the URL in the Response.Redirect becomes:
ctdirectory_secure/deletemember.aspx?id=<%@%20ctdRdr(0)%>
instead of, say:
ctdirectory_secure/deletemember.aspx?id=435
I'm assuming that a <%= expression %> cannot be used to set a control parameter, but how else can I do it?

I'm wondering how is CommandArgument of a button passed to handler at low level.For example if I need to pass few values in CommandArgument what is better - to make it like 134_3554_345 and then parse or to pass an instanse of class like new MyClass(135,3554,345) ?

I'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 need some high-level advice on how to deal with this issue. I want to have dynamically created buttons, each with a different CommandArgument, that call an OnCommand event when clicked. Given that these are dynamic buttons, I have to re-create them in Page_Load after the postback. However, when I re-create the buttons, the orginal command arguments are lost, and the arguments generated after the postback are only valid.As you'd expect, if I don't recreate the buttons, the event handler is never called because the buttons don't exist.My question is, how can I retrieve those original commandarguments, without the use of sessions.

I have a repeater. This gets bound to a data set which contains (amongst others) a field called EntityType and a field called ID. An Entity Type might be "Person" and there might be several categories of "Person". The ID field identifies that category. So there might be a "Person" type 1, a "Person" type 2 and so on. The Entity Type and ID therefore make up a compound primary key.
Nested in each row of the repeater I have a grid view which get populated as a result of clicking an "expand" button in the repeater row. Each row in the GridView represents an "Entity". So "Peter" who's own ID might be, say 59 might be a "Person" of Type 1. So Peter really has a three column primary key consisting of the EntityType and ID field's from the repeater's dataset and the ID from gridview's dataset.
So in order to query the database and fully retrieve Peter, I need that whole primary key. I know how to get the ID from the GridView's dataset, I set Eval("ID") as the CommandArgument for the gridview's button and then consume it in the event. But I don't know how to get at the EntityType or the ID from the Repeater's dataset. How can I do that?
Here's my code at the moment:-
asp Code:
<asp:Repeater ID="ChildClassesRepeater" runat="server" OnItemCommand="ChildClassesRepeater_ItemCommand" Visible ="false" >
<ItemTemplate> <tr> <td> <%# DataBinder.Eval(Container.DataItem, "EntityType")%> </td> <td>
<%# DataBinder.Eval(Container.DataItem, "Class")%> </td> <td>
[Code] ....
I'm thinking the easiest thing to do is put the EntityType and parent ID on the Command Argument where it currently reads IDontKnowWhatGoesHere but I can't work out how to get at them.
Alternatively, is there a way I can get at them in the event handler? I think not but I'm not sure.
I could have the query for the grid view return the parent columns, that would allow me to eval them in the same way as I am the entity ID. That feels like I'm reading redundant data, though, as it's already there in the client - if I could just get at it.

I have added a gridview in my aspx web page. I have added a hyperlink field, to navigate to another page from the gridview. I am getting the error as:
"There was an error rendering the control.
Index(zero based) must be greater than or equal to zero and less than the size of the argument list. "
This is the code i have used:
[Code]....
[Code]....
When i remove the hyperlink, the grid is getting displayed. I know, there is something wrong i have coded in the DataNavigateURLformatstring, but not sure what is wrong.
I want to pass the StudentID,CourseID,ChildImageID with the link as the querystring.

I Have a gridview where I have a link to a details page and I need to pass multiple parameters. I currently have the following:
<Columns>
<asp:BoundField DataField="AssocID" HeaderText="AssocID" InsertVisible="False"
ReadOnly="True" SortExpression="AssocID" />
<asp:BoundField DataField="FirstName" HeaderText="First Name"
SortExpression="FirstName" />
<asp:BoundField DataField="MiddleInitial" HeaderText="M. I."
SortExpression="MiddleInitial" />
<asp:BoundField DataField="LastName" HeaderText="Last Name"
SortExpression="LastName" />
<asp:BoundField DataField="State" HeaderText="State" SortExpression="State" />
<asp:BoundField DataField="EMail1" HeaderText="EMail 1"
SortExpression="EMail1" />
<asp:BoundField DataField="AddrType" HeaderText="Addr Type"
SortExpression="AddrType" />
<asp:HyperLinkField DataNavigateUrlFields="AddrID,AssocID"
DataNavigateUrlFormatString="Details.aspx?AddrID={0}&AssocID={1}" HeaderText="Details"
Text="Details" />
<asp:BoundField DataField="AddrID" HeaderText="AddrID" InsertVisible="False"
ReadOnly="True" SortExpression="AddrID" Visible="False" />
</Columns>
According to all I have read my DataNavagateUrlFields string should work but it isn't. The deal is that any one (AssocID) can have multiple AddrID's associated with it. Regardless of which I choose I only get back the first AddrID for that AssocId.

I have a gridview set up as follows:
[Code]....
Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..

I have a web page with various controls. Two of them are dropdownlists. The first dropdownlist gets populated from an xml file on the page_load event. This works fine. To the first dropdownlist a cascadingdropdownlist extender is attached which calls a webservice each time the selection in the first dropdownlist is changed. This works fine too. Underneath my two dropdownlists I have a button which posts the page back. However, when I have made a selection in the second dropdownlist and click the button I get the following error:
