I have the SelectIndexChanged event wired to my CheckListBox but it does not fire when the last item is unchecked. Is that a bug or do I have to set some property that would alow the event to be fired.

I have a webform that gives the user the option to submit 5 referrals. Currently I only have 1 checklistbox that gives the user a choice to select products of interest for all the referrals. I would like to add a checklistbox under each referral input field in case there are different product interest for each referral? So when the referral gets a confirmation email it contains the product of interest that is specific to that referral.
I am trying to display all images selected in a checklistbox, but am not sure how to write the c#.

I am returning records from the database and I need to compare those records against my checklist box to determine which ones should be checked.
Query is working properly and returning 3 records.
Vehicle ID = 40, Option ID = 1
VehicleID = 40, Option ID = 36
VehicleID = 40, Option ID = 37

This is not working, can anyone point me in the right direction???
i have a checklistbox that is databound during Page_Init in an
If (!Page.IsPostBack)
block. the user can then check off certain values, and click an asp.net button which posts back the form and renders a crystal report on the same page.
i need to be able to determine which items were checked in the control so that they can be used as parameters in the crystal report. rendering must be done during Page_Init.
the checklistbox object is on the page during design time; only the items are dynamic.
i tried using the Request.Form object during Page_Init to obtain the checkboxlist's items but either i didn't code it correctly or it can't be done that way...
can the checkboxlist items' values be obtained during Page_Init, and if so, how?
I have a checklistbox which contains 5 listitems & i have set repetition as vertical now i want to break verticle list after 3 listitems

i my website i am using Repeater control which further contain checkboxlist control. Now my problem is that i have successfully bind "Parameter Type" in repeater control but when i am binding checkbox values, it does't appears in display
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<h4>
<%#Container.DataItem%></h4>
<asp:CheckBoxList ID="chkParList" runat="server" RepeatDirection="Horizontal"
DataTextField = >
</asp:CheckBoxList>
<br /><br />
</ItemTemplate>
<SeparatorTemplate>
<hr />
</SeparatorTemplate>
</asp:Repeater>
In *.cs file following are my code
IMonitoringDataInfo objMonitoringDataInfo = new ChannelFactory<IMonitoringDataInfo>("MonitoringDataInfo").CreateChannel();
Collection<ParameterDetailDTO> clParameterDetailDTO = objMonitoringDataInfo.GetAllParameters(idList, out errorCode);
var parameters = (from resx in clParameterDetailDTO
select resx.ParameterType).Distinct();
Repeater1.DataSource = parameters.ToList();
Repeater1.DataBind();
counter = Repeater1.Items.Count;
while (i < counter - 1)
{
foreach (var parType in parameters)
{
var items = from resx in clParameterDetailDTO
where resx.ParameterType.ToLower().Contains(parType.ToLower())
select new { resx.ParameterName, resx.ParameterID };
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataSource = items;
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataTextField = "ParameterName";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataValueField = "ParameterID";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataBind();
}
i++;
}
I am using LINQ as datasource.
Just want to know if it is possible to Dynamically Populating a DetailsView with OleDb Data Adapter ? It has to be done on the Page_load because it has to display a users details that i must be able to edit!
View 4 RepliesI have a form that has a textbox, a button and a datagridview. The textbox is a parameter of @subschedule. I'm needing to pass the value of the text box to my sql stored procedure and then fill my datagridview with the results of that query.

I'm populating a grid view with data from an SQL datasource. The database has a a list of performing artists and lots of details. The gridview initially, shows the ArtisID (Primary key) , and artist name and music style. So far this is all simple and easy. This is done.
Now I want to be able to click on the ArtistId (Select Column) and move the customer to another page where I show indepth details about the artist. How do I do this???
In Vb.net I had a 'Celldoubleclick' event, and I redirect the client. But how do I accomplish the same in asp.net? I already have the primary key value
primekey = datagridview.selecteddatakey.value
I have a complicate problem. I'm not sure if I can explain it clearly. I have SQL table with columns: id, PartNo, ManuPartNo, GovtPartNum.
My boss want to do like this with 3 dropdown or 1 Dropdown with 2 listbox: If he select any PartNo, it will pull associated value For ManuPartNo & GovtPartNum
Also, if he select any ManuPartNo, it will populate back to other dropdown
Also, if he select any GovtPartNum, it will populate back to other dropdown
I'm so stuck & I don't know where to start on this.
I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

i am using multiview and in View1, i have a gridview.i want to populate my gridview as

this.Gridview1.Databind();

I am trying to list 3 results per line in a list view. I have done 2 results in 1 line using the itemtemplate and alternatingitemtemplate, but how can I get 3 results to show per line?
View 9 RepliesI need to populate the data in the text box according to the values selected in the drop downs.
If the text box is empty it should show a pop up on hitting the save button.
We are using DTO (Data Transfer Object) to populate the data in the drop down and also text box.
I have the following ListView (extra code removed for clarity) :
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?
I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.
Right now I have a datasource populating the formview via the wizard, not sure what to do next.
On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.
