<cmp:MenuItemInfo Text="Delete" onclick="javascript:deleteRow('## DataItem.ClientId ##')" />
In Javascript
function deleteRow(rowId)
{
Projectgrid.deleteItem(Projectgrid.getItemFromClientId(rowId));
}
but the arument is coming as a string '## DataItem.ClientId ##' instead of correct clientID.
I need to be able to evaluate the text value of the template button or pass date from the dbDateOpened colum when the button is pressed. Either direct I have tried gives me an compile error. With the current configuration I get this error. "Object reference not set to an instance of an object."

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" DataKeyNames="ID,dbDateOpened"

I have a datalist control that is querying a accessdatasource for information that populates the results based on w/e is typed in a textbox. I can't figure out how to pass the information that is populated in the datalist to another page when a button is clicked (inside the datalist item template).
I was able to peform this in Detailsview with a hyperlink using the following arguments:
DataNavigateUrlFieldsDataNavigateUrlFormatStringBut this seems not to exist in Detailsview. Could someone point me in a direction on how to acomplish this?
I am trying to figure this up

So, as it may look i want to call MyFunction defined by me with the Id parameter of current object that repeater displays. This is obviously not working.
I have a page that uses a master page. The following code only shows the bare minimum of the page:

My guess is that it may releated to the ID's that are recreated.
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.
Here is my ASP code:
<asp:GridView ID="WagerTable" runat="server" AutoGenerateColumns="False" CssClass="basix" >
<columns>
<asp:BoundField DataField="GameName" HeaderText="Game Name" />
<asp:BoundField DataField="Amount" HeaderText="Amount" />
<asp:BoundField DataField="Comment" HeaderText="Comment" />
<asp:BoundField DataField="CreateTime" HeaderText="Create Time" />
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" Text="Accept" OnClick="AcceptWager" ID="AcceptButton" />
</ItemTemplate>
</asp:TemplateField>
</columns>
</asp:GridView>
This is my code behind:
protected void Page_Load(object sender, EventArgs e)
{
AccountManager accManager = new AccountManager();
MembershipUser newUser = Membership.GetUser(HttpContext.Current.User.Identity.Name);
Guid UserId = (Guid)newUser.ProviderUserKey;
String myConnectionString = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
SqlDataReader reader;
using (SqlConnection myConnection = new SqlConnection(myConnectionString))
{
myConnection.Open();
String selectSql = "SELECT * FROM aspnet_Wagers INNER JOIN aspnet_Games ON aspnet_Wagers.GameId = aspnet_Games.GameId";
SqlCommand myCommand = new SqlCommand(selectSql, myConnection);
myCommand.Parameters.AddWithValue("@UserId", UserId);
reader = myCommand.ExecuteReader();
WagerTable.DataSource = reader;
WagerTable.DataBind();
myConnection.Close();
}
}
protected void AcceptWager()
{
}
I want to be able to have it so that each LinkButton can pass through an ID from the database as an parameter into the AcceptWager function and then I will do with it from there. The sql column for the ID is WagerId. It is returned in that query that i execute, so it is already in the reader.
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?
I have a GridView with an image button in a TemplateField in the last column.
I would like to pass the GridView row values (Bound Field Values - a record) to a JavaScript function to create another html table of selected records in ClientSide (like jCart-A shopping cart).
I would like to know how to pass all GridView column values to the javascript when the image at the end of the respective row is clicked.
I have been stuck on how to pass multiple to a JavaScript function in a item template of a list view. Below is my code. Does anyone know the process?

I can't call javascript function with 1 argument from C# as the code below:
Page.ClientScript.RegisterStartupScript(this.GetType(), "openpopup"
, "<script language="javascript">openUp(index.text);</script>");
in aspx:
function checkFunction(no,name){
}
in cs:
string test_name ="hello";
StringBuilder Strname=new StringBuilder();
Strname.AppendLine("<td ><input type=checkbox onclick='checkFunction("+no+","+test_name+");' runat='server' name='checkbox_name' value='XX'</td>");
when i call the checkFunction(), i can't pass the 2 argument as there is error.

I get an error with the using the <% %> within the onclick.
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 wrote a function in code behind of the aspx file to get from an SQL database the imageurl and assign it to that image's URL. This works fine so I decided to move it to a class but now the imageurl does not exist because the passed image control is now refering to system.drawing.image not the web image.
Code:
Public Sub ShowCodeImages(sProdCode As String, ByRef imgCode As Control, sConnectionString As String)
Dim sSQL As String
Dim sqlDCStock As New SqlConnection
Dim sqlDAStock As SqlDataAdapter
Dim sqlDTStock As DataTable

I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
I need to pass DBNull to a table adapter expecting int, the solution listed below does not work,
int NetID = DBNull.Value;
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 want to pass some argument to javascript function from code behind. My Javascript function as follow. how to send arg to this func. from server side code.
function addTab(tabid,tablist) {
//to Find the Panel
var Panel = $find("<%=RadPanelBar2.ClientID %>");
//To find the Tab Strip
var tabStrip = Panel._findItemByValue("QueueGridPanel").findControl("RadTabStrip2")
tabStrip.get_tabs().clear();
var newTabNames = "MyTab1,MyTab2,MyTab3";
//var newTabNames = document.getElementById("ctl00_GridContentPlaceHolder_hfTabs").value;
var TabsNames = newTabNames.split(',');
var i = 0;
while (i < TabsNames.length) {
var ntab = new Telerik.Web.UI.RadTab();
tabStrip.get_tabs().add(ntab);
ntab.set_text(TabsNames[i]);
i++;
}
return false;
}
I have tried almost evrything and nothing seems to work,,, I dont see errors but the code is not firing when I bind in the properties of the button control ,,nor the code behind.

In my asp.net web page i have a dropdown box. Say like i have to bind EmployeeName to this dropdown box to show up as items.
I am using a dataTable to bind to this grid by having two columns in DataTable (EmployeeId and EmployeeName). But i am only binding the EmployeeName to the dropdown list box.
In the UI, after the user selects an Employee, I need to pass that employee's id to a function. Is there any way, i can directly pass the underlying data (EmployeeID in the DataTable attached to this dropdown), when the user selects the EmployeeName from the dropdown. Or i will have to make a roundtrip to the database and get the selected Employee's Id and then pass it to the function.
In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.
I have a Datalist Which is Bind with Database..Datalist Displays Image And their Image Name.. Now i Want Details of Selected Image from Database in Next View (View 2).
Also Want to know which control should i use for click event on Image??ImageButton or <a Href="">?My Code is --
<asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0" >
<asp:View ID="View1" runat="server">
<asp:DataList ID="DataList1" runat="server" CellPadding="2" CellSpacing="2"
Font-Bold="False" Font-Italic="False" Font-Overline="False"
