I am a new ASP.NET developer and trying to use a GridView control as a way for managing the employees in each division. This GridView will show all the employees in the employee table in the database. Now, I am facing the following problem:
FYI, I have the following database design:
Employee Table: Username, Name, JobTitle, BadgeNo, IsActive, DivisionCode
Divisions Table: SapCode, DivisionShortcut
(IsActive is like a flag (bit datatype) to indicate if the employee is in an assignment or not)
IsActive will be displayed in the GridView as a Checkbox. If it is checked, it means true and the employee is existed in his division. if it is not checked, it means the employee is not with the division, and it should be hidden from the GridView. So how to do that? Also, I want to hide (True) text that appears besides the checkbox in the Edit mode. How to do that, too?
ASP.NET code:
<asp:TemplateField HeaderText="Is Active?">
<ItemTemplate>
<%# Eval("IsActive")%>
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="isActive" runat="server" Text='<%# Bind("IsActive")%>' />
</EditItemTemplate>
</asp:TemplateField>
UPDATE:
I want the employee with all of his information to hidden from the GridView since he is inactive.
Try this
<asp:CheckBox ID="isActive" runat="server" Visible='<%# Bind("IsActive")%>' Text='<%# Bind("IsActive")%>' />
Use this instead.
Have removed the text property, so that IsActive would not be visible. Visiblity is controled by IsActive Flag
<asp:TemplateField HeaderText="Is Active?">
<ItemTemplate>
<%# Eval("IsActive")%>
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="isActive" runat="server" Checked='<%# Eval("IsActive").ToString().Equals("True") %> />
</EditItemTemplate>
</asp:TemplateField>
EDIT
If you want entire row to be hidden for inactive user, you could best to do is filter the inactive user from dataset, before you do a databind() operation. You could even filter it at database end also, but since I do not know the entire scenario, I am suggesting you this.
DataSet filter = ds.Tables[0].Select("IsActive == 'True'");
gridUser.DataSource = filter;
gridUser.DataBind();

I'm wondering if it is possible to format a Grid View like the pattern below
Usual Grid View:
Name Address Age Gender <--- Fields Name
Example Example Example Example <--- Values
What I want to look like
"Fields" "Values"
Name Example
Address Example
Age Example
Gender Example
Any thought will be highly appreciated
you should look into using a repeater.
I think that GridView was simply not meant to be used that way. Usually, you will display several items in it and if those items are too many you will end up with the horizontal scrolling mistake (also, some nice arguments here).
If you are showing only one record, you should use a DetailsView control, which:
Displays the values of a single record from a data source in a table,
where each data row represents a field of the record. The DetailsView
control allows you to edit, delete, and insert records.
I got an Answer using this Codes:
<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="False" >
<Columns>
<asp:TemplateField HeaderText="">
<ItemTemplate>
Name: <asp:Label ID="Label1" runat="server" Text='<%# Eval("Name") %>'></asp:Label><br />
Address: <asp:Label ID="Label2" runat="server" Text='<%# Eval("Address") %>'></asp:Label><br />
Postcode: <asp:Label ID="Label3" runat="server" Text='<%# Eval("Postcode") %>'></asp:Label><br />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I have created a dropdown list in a DetailsView control
I want to make that dropdown have multiple columns. Is that possible? If So how?
I've done a lot of searching and cant seem to find the solution.
Below is the code for my dropdown template:
<asp:TemplateField HeaderText="Division" SortExpression="fDivisionID">
<EditItemTemplate>
<asp:DropDownList
ID="DivisionDropDownList"
runat="server"
DataSourceID="DivisionSqlDataSource"
DataTextField="DivisionName"
DataValueField="DivisionID"
Text='<%# Bind("fDivisionID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("DivisionName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
How do I add another column to that.. such as "Location"..
Thanks in advance
There are I think three ways actually.
Add two columns in your Select statement when fetching from database like below. or from here
Select Column1 + ' ' + Column2 From Yourtable
You can use third party controls.
Jquery Also supports this feature Here
I have a student enrollment gridview populated with Enrollment objects. The Enrollment object has student Id. With that Id, I am populating 2 columns (from 3 properties of Student object) of enrollment gridview.
Right now, I am doing it with below code. This means 3 round trips to database for the same object, which is so very bad. How can I use the same object to get the 3 properties?
<asp:TemplateField HeaderText="Student Name">
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%# string.Format("{0} - {1}", StudentProfile.GetStudentProfileById(Convert.ToInt32(Eval("StudentId"))).FirstName, StudentProfile.GetStudentProfileById(Convert.ToInt32(Eval("StudentId"))).Surname) %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Student DOB">
<ItemTemplate>
<asp:Label ID="lblDOB" runat="server" Text='<%# StudentProfile.GetStudentProfileById(Convert.ToInt32(Eval("StudentId"))).DateOfBirth %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Edit: FYI, I have to deal with updating the gridview rows which will involve adding textboxes and so to each row. Can you please keep the answers apt to this point?
Thank you very much!
The way you are binding data to the gridview is wrong. You need to get the Data in an Object/Collection and then bind that data as a DataSource to your GridView.
Take a look here Displaying Data With the ObjectDataSource and look at this as well Querying Data with the SqlDataSource Control
i think this maybe an easy one...
I have a Gridview, bound to a dataSource with this query:
select userid, name, phone from users
I need to change the content of the Name cell to a link, like so:
User's Name
so OnRowDataBound i'm doing this:
e.Row.Cells[1].Text = "" + e.Row.Cells[1].Text + "";
It all works fine this way. My problem is that i don't want to display the UserId column in the Gridview, but when i attribute it (asp attribute or server-side) Visible="false" to the BoundField UserId, i can't capture it's value to build the Name Cell.
Thanx for your help
Make your gridView to use template items instead of simple grivdiew column.
<asp:TemplateField HeaderText="FirstName" SortExpression="FirstName">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("FirstName")%>'>
</asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("FirstName") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
You can find a nice intro Here
Agree with Jani, this should be done with a template field. If you really need to do it the other way, see Can data be kept in a dynamically bound GridView's invisible fields?.
you can set the visibility on the onrowdatabound event
Ok, this should be really easy, but I just don't have enough experience.
I need to throw a GridView on a WebForm and populate with a List, where Template is my class that has ID, Name, CreatedOn, etc... properties.
The GridView needs to display each Template Name as a link. The link should point to TemplateEdit.aspx page, with the following URL: TemplateEdit.aspx?ID={ID of Template}.
I also need a Delete link (preferably an image link), that should popup a Yes/No delete confirmation dialog.
I've actually done this before in 2005 or so, but I simply can't remember anymore.
Here's how you do it (borrowed the code from here to save some typing)
<asp:TemplateField HeaderText="Statement" SortExpression="Statement">
<ItemTemplate>
<asp:HyperLink ID="Link1" runat="server" NavigateUrl='<%# Bind("ID", "~/TemplateEdit.aspx?ID={0}") %>' Text="The Best Link"></asp:HyperLink >
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="DeleteButton" Runat="server" ImageUrl="~/images/delete.gif" OnClientClick="return confirm('Are you sure you want to delete this?');" ToolTip="Delete" CommandName="Delete" />
</ItemTemplate>
</asp:TemplateField>
didn't actually test it, but looks like it should work.
