Forms Data Controls :: Code And Run It, It Show Nothing?
Oct 22, 2010
I'm doing chart running in application using C# VS2010 to make my Chart Xaxis move.when i place my code and run it, it show nothing. so i created another program using vb.net using the same code as C# yet my vb.net code allow me to make my Chart Xaxis moving.moving mean from 1pm to 1.10pm and so on.which mean my minimum of the chart and maximum will keep moving.
I am creating a gridview that inherits from a webpart. Code runs with out the error but just shows a blank page. I am looking for an example of the page directive, register and user control tags. I am not sure what other steps I need to take to show the gridview on the aspx page. Here is the code:
Protected Sub GridView2_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) If GridView2.Rows.Count > 0 Then Button1.Visible = True [code]...
I SIMPLY want to show a line of text on the page: "This zip code is not in our database..." in addition to the "Else" statement of "Button1.Visible = False"
I cannot get my controls to show in the code-behind page. There are several errors showing that they are not defined...but when I run the project, everything is fine.I just have no intellisense and have to write all of my events out.
I have web form in c# asp.net. I have an textbox where the user can enter some part number. When he click on the search button I would like to do some validation of the search text. It is not possible to use the following charachters (- _ / . spaces). When the custom validation found one of these characters I would like to show some error message (It is not possible to use one of these special characters: -, _, /, , . and spaces.). And than I would like to remove the special characters from the search text and execute a method to search.Can I do it with a custom validation like:
<asp:textbox id="TextBox1" runat="server"></asp:textbox><asp:CustomValidator id="CustomValidator1" runat="server" OnServerValidate="TextValidate" ControlToValidate="TextBox1" ErrorMessage="It is not possible to use one of these special characters: -, _, /, , . and spaces."></asp:CustomValidator> protected void TextValidate(object source, ServerValidateEventArgs args){ args.IsValid = (args.Value.Contains(""); string newSearchValue = // remove the special characters -, _, /, , . and spaces. // Run the search method without the special character, but show a error message search(newSearchValue);}
I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.
I have an example here of what I am trying to accomplish:
I want to show video in my page but i don't know how to do it? i want to save embed code of video from you tube in my access DB , and show the video on btn_click.
I am looking for a way to display an iframe code part in my website. Also, I am looking for a component to make it easy to copy/paste this iframe code part.
I am using an ADO Entity Model for my ms-sql database.
My database has a Resellers table which has ResellerID (primary key, int) and Name columns along with other data.
I also have an Orders table which contains OrderID (primary key, int), OrderDate, ResellerID (foreign key to Resellers.ReselerID).
If I just do a query like:
[Code]....
I am able to reference order.Reseller.Name just fine with no problems.
However I have an EntityDataSource on my page as follows:
[Code]....
Notice the Include="Reseller" attribute in the datasource... I also have a GridView tied to that datasource as follows: I cut some of it off for breavity:
[Code]....
Now what I have listed above will run with no errors, but what I want to do is replace the column that displays "ResellerID" with the equivilant to order.Reseller.Name. In other words I want my grid to display the reseller's name rather than the numeric ID.
I have tried to change the DataField to "Reseller.Name" but that will generate the following error:
A field or property with the name 'Reseller.Name' was not found on the selected data source.
Is there anyway to do this without me writing a custom select statement in my code behind?
What I want to do is to replace number with a name. So if in the Month Column it receives five "1" it changes those 5 "1" to JANUARY.
Is it possible? This is because unfortunately I can only arrange my months by number and not by their name, this because of my queries and tables format, so, I thought maybe I can tell the gridview to change the month number to their relative month name.
I m Using DataList Controll for the time being. But i wana use DridView Controll that should display Data Horizontally. Is it Possible? if Yes then How?
I am using gridview for my application, in the grid i am using dropdown list for two columns ,It's working when i run my application but when i am edit application ddl can't show the editable data ( it show only select).And one more thing that two columns are interrelated , one ddl(Itemgroup) is connected with(ItemName).
I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):
[Code]....
But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work
I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.
In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.
It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.
Im not sure what control to use, I want to show a list of results in teh following format
Car Name Ford Fiat Opel Car Accessory Leather Yes No Yes Power Steering Yes Yes Yes Electric Windows No Yes Yes
Should I use a repeater, gridview or listview. The bit I cant get my head round is how I get the 1st column to show Leather, Power Steering, Electric Windows etc....
