I have a dgv with a column type = DataGridViewAutoFilterCheckBoxColumn. I want to know if there's a way to I can get that entire column to become disabled (or Enabled = False) so it won't let the user click on the checkboxes.
I tried looking in the "Bound Column Properties" but there isn't an option to disable the entire column.
I really hope I'm missing something, but I cannot for the life of me figure out a simple way to do the following: I have a database with a list of Ids, Names, and a bit field representing a boolean. Example:
Id | Name | Active
21 BoB 1
43 Ron 0
23 Tom 1
All I want is to list the names on my webpage, with check boxes beside them, and when I click the checkbox the database automatically changes the status... that's it. A checkedlistbox control would be amazing, but it doesn't seem to exist in web form. The problem with checkboxes is asp:checkbox doesn't have a "value" field anymore. So when I'm handling CheckedChanged event, I have no way of knowing what the Id of the changed entry is. I have seen a couple things online that require searching through control hierarchies to find some Id somewhere in your dataset, but that does not make sense.There MUST be a way to do something like this:
[Code]....
At this point I think it's easier to use 2 list boxes, 1 that lists people where Active=0 and one that lists people where Active=1 and then an OnSelect event that moves them between each other. That's how easy checkboxes SHOULD be.
For example, let's say I have a HyperLink:
<asp:HyperLink runat="server" Text="Foo" NavigateUrl="foo.aspx" />
How can I set the NavigateUrl on the server side, without having to go the code-behind?
This doesn't work of course:
<asp:HyperLink runat="server" Text="Foo" NavigateUrl="<%= urlString %>" />
(where urlString might be a string I created earlier in the page)And this doesn't work because the HyperLink is not within a data bound control:
<asp:HyperLink runat="server" Text="Foo" NavigateUrl='<%# urlString %>' />
I guess I could just use a standard anchor element:
<a href="<%= urlString %>">Foo</a>
But I'd rather not mix up HTML and ASP.NET controls, and it would be handy to be able to do this for other controls.
eI am using themes to set the Gridview font size and font name. I need to set the boundfield to the same font and size as I want it to be application to all the columns in gridview. How can I specify the boundfield properties in the themes.
View 8 RepliesI have added a partial class to one generated by the Entity Framework. I wanted to add a calculated field that I could bind to my GridView. However, when I try to access the new property, I get an error message that this is a limitation to Entity Framework.Are there any work arounds to accomplish this?
View 1 RepliesIs it possible to put a column of checkboxes in the ReportViewer so that a user can select multiple records and then click a button to have those records processed as a group?
View 1 RepliesI have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
I have a gridview and now I need to add a column with checkboxes.
The checkboxes need to be checked or unchecked depending on the data retrieved.
I have a DataGrid with a TemplateColumn containing an asp:DropDownList and a BoundColumn. I'd like to have a VB.NET handler for when the selected item in the DropDownList changes. I'd like this handler to also update the value in the BoundColumn with the value of the newly selected item in the DropDownList.
Can someone point me to some resources I can examine to learn how to do this?
If the handler for the selection changing can give me the value of the NEWLY selected item, it should just be a matter of accessing the cell for my BoundColumn in the same row and writing to it. I do not know the syntax to achieve this.
I have a TextBox bound to a decimal column and want to drop any zeros to right of decimal point. So 8.0000 shows as 8 and 7.6000 shows as 7.6.Currently the Text property is #Bind("Units", "{0:n2}")
View 1 RepliesI've got a typed dataset that populates programmatically based upon dropdown selections from the user, and then is bound to a datagrid. One of the cols is a bit type (indicating whether or not that record is "active"). I would like that datagrid col to be exposed to the user as a bunch of checkboxes, which the user could turn on and off as needed, and then update the entire recordset according upon clicking Submit.
Is converting a dg column into checkboxes a straightforward thing to do?
I'm trying to populate a date from a bound text field in a DetailsView. I keep getting a error when a DBNull is in the column. How do I avoid the DBNull when populating the text field.My code is as follows:

<EditItemTemplate>
<asp:TextBox ID="CBYDExpDate" runat="server" ReadOnly="true" Text='<%# IIf(Eval("CBYDDate") is DBNull.Value,"", String.Format("{0:MM/dd/yyyy}", Eval("CBYDDate").AddDays(30)))%>' />

View 1 RepliesI have a gridview with checkbox. I have this code on a RowDataBound Event
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString)) [code]....
But the problem now is everytime I click the checkboxes I am redirected to a page because I have a Response.Redirect in SelectedIndexChanged event. How can I be able select a checkboxes and redicrect only when I click in a certain column.

I have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.
I am having trouble with displaying double data in gridview bound coulumn. I want it to display as it is... But it gets rounded off when displayed.
Like my 1.34 displays 1.00

Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)
