Web Forms :: Populating A Dynamically Generated Checklist Control In Code-behind Not Working?
(The following is a complete re-edit of the original post which was rambling, confusing etc...) I have a form with a dynamically generated checklist: <asp:CheckBoxList ID="cblGames" runat="server" DataSourceID="sqlGames" DataTextField="Game" DataValueField="Id" </asp:CheckBoxList> <asp:SqlDataSource ID="sqlGames" runat="server" ConnectionString="<%$ ConnectionStrings:Games %>" SelectCommand="SELECT [Id], [Game], [ShowWaitingList] FROM [Aanbod] WHERE ([ShowWaitingList] = @ShowWaitingList)"> <SelectParameters><asp:Parameter DefaultValue="true" Name="ShowWaitingList" Type="Boolean" /></SelectParameters> </asp:SqlDataSource> The following code-behind is supposed to check those boxes that correspond to values stored in a database. It fails and I don't know why. [Code]....

Forms Data Controls :: Populating Dropdownlist Inside Listview Control Dynamically?
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.

Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview. This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate. [Code]....

Web Forms :: Dynamically Populating A Page?
I'm currently building my website and have hit a brick wall. I've not begun coding anything fro this yet as I am unable to get my head around it and not sure where to start. I've got a database table with a list of town/ county names ( columns are id, town, county). What I'd like to do is have a template page with set places for town/ county names and then when a particular area is searched for in google/ bing etc my template page with the relevant town/ county name is shown. I know that's a bit vague so if you have any questions, let me know. One thing I don't want to do is manually create a page for each individual town/ county!

Forms Data Controls :: Populating A ListBox In A Repeater Control Residing In A ContentPlaceHolder Control
I have a ContentPlaceHolder control that contains a repeater control that contains several databound controls. The repeater control is bound to a DataTable. One of the databound controls on the repeater is a ListBox control. Per the requirements of my customer, the ListBox control will need be populated with numeric values ranging from 0 to 100 in increments of 5. The problem with this ListBox control is that there will be occasions where some data will be non-divisible by 5. On these occasions, the data value is to be inserted into my list of 0 to 100. For example, most ListBoxes will be populated and bound with a value of 0 to 100 in increments of 5 (0, 5, 10, 15, etc) but SOME will occasionally need to populate and bind with an additional integer of, say, 3. I have tried to populate the ListBox with non-data-bound items and then do the binding later but I am having difficulties with that. To insert the non-divisible by 5 value, I would need to know which repeater item contains the corresponding drop-down list. I can try to query the for for the ContentPlaceHolder AND the Repeater AND the ListBox but they are all dynamically created so locating the control is difficult. This will probably be one of those posts that do not get answered. The .aspx code is: <asp:ListBox ID="lbCodeWeight" runat="server" SelectionMode="Single" DataTextField="CodeWeight" DataValueField="PerfGrp" Rows="1" onchange="javascript:updateTotal()" Font-Overline="False"> </asp:ListBox> Here is some c# code that I have thus far with "appraisal" being the name of the Repeater: private void PopulateAppraisals() { if (Cache["dt1"] != null && dt1 == null) { dt1 = (DataTable)Cache["dt1"]; } appraisal.DataSource = dt1; appraisal.DataBind(); foreach (RepeaterItem item in Appraisal.Items) { ListBox lb = (ListBox)item.FindControl("lbCodeWeight"); if (lb != null) { int i = 0; while (i <= 100) { ListItem li = new ListItem(); li.Text = i.ToString(); lb.Items.Add(li); i = i + 5; } } } foreach (DataRow row in dt1.Rows) { int i = Convert.ToInt32(row["CodeWeight"]); if (i % 5 != 0) { foreach (RepeaterItem item in Appraisal.Items) { ListBox lb = (ListBox)item.FindControl("lbCodeWeight"); if (lb != null) { //find the listbox control that will need this listitem added //then bind //then set as selectedvalue } } } } }

AJAX :: Dynamically Populating Tabs Using Gridview?
I've got a gridview control embedded within a tabpanel and an update panel. I have a few columns from the database showing in the gridview and in order to see all the columns corresponding to that row, I want to open a separate tabpanel upon gridview selected index changed event. At the moment, I'm using the code below to add new tabs: [Code].... Problem is that upon clicking on the gridview select button, I manage to add a new tab, but after this, the gridview control gets locked up and stops working (stops from selecting any other rows). In the code above, I'm rebuilding all the tabs (including the one containing the gridview), after going through forums articles. However, I've also tried doing it the simple way but it didn't work: [Code]....

Forms Data Controls :: Dynamically Populating Fields In A Gridview Depending On Data In A Table?
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?

Web Forms :: Populating A Ordered List In A User Control?
I have a upload section on a user control <div class="AttachQuote"><fieldset> <legend>Quote(s)</legend> <asp:Button ID="btnAttachQuote" UseSubmitBehavior="false" Text="Attach Quote" runat="server" /> <ol id="olUploadedFiles" style="list-style-type: decimal; padding-left: 30px;"> </ol></fieldset></div> the btnAttachQuote is defined as protected global::System.Web.UI.WebControls.Button btnAttachQuote; can i do something simular to olUploadedFiles? there are alot of list options in webcontrols and i'm unsure how to use them. I would like to use a for loop to populate olUploadedFiles from a string array in my .cs. something like ... int i = 0; while (files[i].Length !=0) { olUploadedFiles.add (files[i]);//i'll substring the file names out i++; } I'm using the same control for both the form submit and the status page(label only mode). I can load the rest of the info i just can't populate the dropdown from the codebehind.

Forms Data Controls :: Populating List Control Without Database?
I have a web form which I plan on using to upload a bunch of files to, one at a time. Once all the files have been uploaded, I plan on adding a routine to add them all the an MSSQL table, but need to know how I can retain them before uploading? I've considered: 1. Uploading to the server (one at a time), and then adding each to the table from where they are physical stored temporarily on the server - with a single routine. 2. Capturing, the file data as binary, the file name and MIME Type and storing it in a DataTable with other uploaded files before submitting to the database. I think the first option is probably the most viable of the two? Either way, I still need someway of retaining information before finally submitting it all the Database.

Web Forms :: To Dynamically Create A Div Containing A Dynamically Created Image Control?
I am relatively new to asp and progressing slowly - searching for what I need and generally finding it and then applying it.I am creating an agency web site which shows the photos of its members, these are pulled from a db according to the member ID. I can do all this but getting them to display in a web form is proving impossible.The problem is that there will be a various number of photos per member - minimum 1 but there could be 5 or 6. I want each thumbnail image to be shown in a <div> with a defined style in a stylesheet - basically so they all look the same and will 'float, so as to layout nicely without using tables. So I need on a page load to count the number of images (I can do that) and then dynamically create the appropriate number of <div> elements AND dynamically create an image control within each of the dynamically created <div>'s I have found some info on dynamically creating the <div>'s and on dynamically creating the image controls BUT how to bring them together so I get a dynamically created image control within a dynamically created <div> ?
