C# - How To Set A Custom Id For Listitems In BulletedList Control While Binding
Mar 8, 2010
I am binding a BulletedList control in page load to a datasource, what i want to do is to set custom IDs for this BulletedList's ListItems while binding This custom ID will be in my current case "li_"+ItemId.ToString()
Sample Code i used to fill the bulletedList:
bulletedList.DataSource = MyDataCollection;
bulletedList.DataTextField = "Name";
bulletedList.DataValueField = "Id";
bulletedList.DataBind();

The following code always comes out with the error:
"The server tag 'asp:BulletedList' is is ambiguous. Please modify the associated registration that is causing ambiguity and pick a new tag prefix".

I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.
I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.
If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.
However I'd rather not have to do this, instead the control should bind itself.
I gather it's something to do with the order of events but I'm not sure what to do about it.
I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data
Sample code (some code removed for clarity)

I've different buttons like this
<asp:Button ID="button1" runat="server" Text="single" title="single" EnableViewState="false" />
When this button is clicked I want that the text in a list like this changes
<asp:BulletedList ID="list1" runat="server" EnableViewState="false">
<asp:ListItem>Item1</asp:ListItem>
<asp:ListItem>Item2</asp:ListItem>
<asp:ListItem>Item3</asp:ListItem>
<asp:ListItem>Item4</asp:ListItem>
</asp:BulletedList>
How in C# can I select the first, the second or the third element of the list?
protected button_Click(object sender, EventArgs e)
{
list1. ...;
}

I'm trying to use a BulletedList to output some links. When the list renders, all the link tags are encoded, so they are displayed to the user instead of being rendered as links.
Is there a way to make the BulletedList not do this? I'm doing a foreach over a custom object collection where each object has a string representing a link as a property. I just want to build a list of links and I thought a BulletedList was a good way to do it. Is there a better way or a way that doesn't encode the output?

I have a BulletedList in ASP.NET
<asp:BulletedList ID="lstItems" OnClick="Item_OnClick" DisplayMode="LinkButton" runat="server" />
On the server I handle the list item's link button click event.
When this occurs I want to apply a CSS class to the selected item on the client-side to show that it is the selected item.
Since ListItem does not support any sort of CSS properties directly, but does support Selected, I assume the best way to do this would be to get the selected item from control on the page load and apply the styling then.
Does anyone know how to access this property in JavaScript or any other options to achieve this affect?

let me say i am an amateur in c# and asp.net so i would like to say sorry in advance if i am asking something obvious for the rest of you. :) I have this code that i use to populate a BulletedList in my page with the current roles in the site + some extra information.o far, since all these are text related, no problem.Now i would like to have a LinkButton control at the end of the role string which if pressed it will delete the role (and repopulate the list) (like the functionality that the admin tool in visual studio has)My question(s) is: Is there a way to do that in a bulleted list or should i use another control (like a gridview, although my experience with this is limited)
private void BindRolesToList()
{
string[] roles = Roles.GetAllRoles();

I have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.
I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".
I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:
protected override void OnPreRender(EventArgs e)
{
// Do as usual
base.OnPreRender(e);
// Adjust each data row
foreach (GridViewRow r in Rows)
{
// Get the appropriate style object for the row
TableItemStyle style = GetRowStyleFromState(r.RowState);
// Retrieve the reference to the checkbox
CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID);
// Build the ID of the checkbox in the header
string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID);
// Add script code to enable selection
cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')",
SelectedRowStyle.CssClass,
style.CssClass,
headerCheckBoxID);
// Update the style of the checkbox if checked
if (cb.Checked)
{
r.BackColor = SelectedRowStyle.BackColor;
r.ForeColor = SelectedRowStyle.ForeColor;
r.Font.Bold = SelectedRowStyle.Font.Bold;
}
else
{
r.BackColor = style.BackColor;
r.ForeColor = style.ForeColor;
r.Font.Bold = style.Font.Bold;
}
}
}

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

here's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.
My Server Control Code is as follows:

I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.
What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.
However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.

I have a Gridview that displays paged results from a search query. The problem I am having is that the gridview is not displaying all the results returned from the query. For example, I can step through the code and see 6 items returned by the call to GetList(), but only 2 rows get rendered by the gridview after binding.
I am using an ObjectDataSource created in code:
ObjectDataSource ods = new ObjectDataSource();
ods.EnablePaging = true;
ods.TypeName = "Bll.InvestmentProductSvc";
ods.DataObjectTypeName = "Bll.InvestmentProduct";
ods.SelectMethod = "GetList";
ods.SelectCountMethod = "GetListCount";
ods.StartRowIndexParameterName = "PageIndex";
ods.MaximumRowsParameterName = "PageSize";
ods.EnableViewState = false;
ods.SelectParameters.Add (new Parameter("SearchString",TypeCode.String, SearchString));
ods.SelectParameters.Add(new Parameter("PageIndex", TypeCode.Int32));
ods.SelectParameters.Add(new Parameter("PageSize", TypeCode.Int32, gvSearchResults.PageSize.ToString()));
gvSearchResults.DataSource = ods;
gvSearchResults.DataBind();
The Gridview declaration:
<asp:GridView ID="gvSearchResults" runat="server" AutoGenerateColumns="False" AllowPaging="true" PageIndex="0" PageSize="50" OnPageIndexChanging="gvSearchResults_PageIndexChanging" PagerSettings-Position="TopAndBottom">
</asp:GridView>
Are there any reasons for the Gridview not to render a row and not to report an error? I have examined the data returned for the 6 items and cannot find any distinctive differences between the 2 rows displayed and the 4 rows not displayed.

I'll use Customer and Addresses as an example rather than explain my real objects. Say I have a repeater bound to a collection of Customers and one of the properties of Customer is an array of addresses. How do I bind to the addresses property? I don't even need to display this information I just want to use it in the Repeaters ItemDataBound event. So I tried to bind a hiddenField to the addresses property but all I get for every customer in the hiddenfields value is an empty array of addresses.

I have a question about model binding. Imagine you have an existing database entity displayed in a form and you'd like to edit some details, some properties eg createddate etc are not bound to the form, during model binding, these properties are not assigned to the model as they are not on the http post data or querystrong etc, hence their properties are null. In my controller method for update , Id just like to do
public ActionResult Update( Entity ent)
{
//Save changes to db
}
but as some properties are null in ent, they override the existing database fields which are not part of the form post data, What is the correct way to handle this? Ive tried hidden fields to hold the data, but model binding does not seem to assign hidden fields to the model.

I have an ASCX that inherits from a WebControl that has a 'CustomConfiguration' property of type CollectionConfigurationItem. This configuration gets set elsewhere in the code, so by the time it gets to the ASCX it is set up to how I wish to use the data. At this point I'd like to render out another control using this configuration, like so:
<modules:DataModule runat="server" CustomConfiguration="<%# Model.CategoryListConfiguration %>" />
However, breaking into DataModule always results in 'CustomConfiguration' being null, which is the default value for the property. I've tried adding a Bindable attribute to the property but to no avail, and when I set an EventHandler for the DataBinding event on the DataModule it doesn't even get called.
How can I set this custom-class-typed property from the markup or, failing that what's the second-best method of getting this to work?

I have been reading alot about this and for some reason I am just not able to grasp the concept. Hopefully someone here can enlighten me.As an example situation I have a collection of strongly typed User objects that represent a database table, and some properties that represent its columns: UserID(PK), Username,FirstName,LastName, etc..Here are some of my requirements/goals:1. Users/Objects needs to be bound to the gridview programatically.2. I do not want to update the database right away, I only want the underlying collection to be updated. I would like to call the database update method myself when I am ready.
3. I do not want the primary key stored on the client side.Summary:So I bind a List<Users> to a gridview with the appropriate bound fields set up, I exlude bound fields such as primary key because I don't want it being changed/hacked by the client side. When I edit and update a row it is saved back to the collection of objects. I will iterate through the objects manually at a later time and commit them to database.
Questions:1. Can I cast a gridview row directly back to my object, in the RowUpdating or RowUpdated events? I am assuming I can't... So....2. How can I reference back my original collection if the gridview does not contain a primary key?3. Where do I store my collection, should it be in Session or should I recreate it on each postback?Sorry if any of this is confusing, let me know if you need clarification.
