I wanted to know whether this is possible or not. I have a page with a div. I populate div at run time with a HTML table I wanted to access that table to get the data back.
I am trying with ParseControl() method... Not success Yet.
I created a aesthetic control that creates two lists in seperate div tags organized with a table for each. The control always the user to click on the img tag associated with each item to move it between the two lists. I am doing all the movement between the lists via javascript and want to have a good method for obtaining the values and storing them in two lists upon Postback. I thought of doing something like storing the indexes/classes in hidden values and them reading them to find the items but that seems messy. Also, thought there might be a clever way of traversing the DOM via FindControl() but not sure. Any input would be great.
One other thing is that this is not a composite control. All the tags are being rendered in the RenderContents() method. So I don't know if there is a way to even tack on a runat="server" attribute to an elem like I normally would if I wanted code behind access to an html element.
Here is the HTML that is generated. I don't think there is need to post the server side code since it does nothing more than generate the html at this point.
<div class="DualListPanel" id="test1">
<div key="test1_Unassigned">
<table class="DLPTable">
<tr>
<td>Item 1</td>
<td><img src="..." onclick="Move(this)" /></td>
</tr>
<tr>
<td>Item 2</td>
<td><img src="..." onclick="Move(this)" /></td>
</tr>
</table>
</div>
<div key="test1_Assigned">
<table class="DLPTable">
</table
</div>
</div>
I have a question about asp.net
I have this table with checkbox for each row:
[URL]
table code inside the ASPX page:
[URL]
So I'm trying to implement the delete selected button.. How exactly do i point to the specific checkbox for a particular row from codebehind when all 3 have the same name chkSelected? I know how to do it with a gridview, but not quite sure how if we do it with a for loop..
Can I do something like this inside btnDelete_Click?

Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back. In my example, I have a Class called "Ingredient" which has 4 public accessories: Name, Barcode, Amount, and Unit.
[Code]....
Or is this not possible? (Basically, I'm trying to re-create a datagrid where certain fields are editable and certain are not...)
I have a table that the user can add rows to through javascript by clicking on a "add rows button". In each row there are two columns one with a dropdown list and the other a text box. The dropdown list is populated with data through a sub on server side code.I need to be able to insert the data from each row into a table but I'm unable to do this. I clicked on my "add rows button" to add several rows and then did a test to see how many rows the table was returning on the server side and it did not include the five rows I added .. only the header row.If there is a better way to allow users to dynamically add rows to a table and then access the dynamically created table on the server then I'm all ears!
View 3 RepliesI've a grid view which could have huge data. When any control like a button causes the postback, I do not want gridview data to post back as it is not required and results in slower responses.
View 1 RepliesFollowing code is an example, I just want to know if this can be done. I have an test.aspx file with this server side include tag;
<!--#include file="listOfCountries.htm" -->
Within listOfCountries.htm, I have:
<html>
<div>
<select id="countryList" runat="server">
<option></option>
...
</select>
</div>
</html>
Now, Is there a way to access "countryList" in test.aspx.cs file? On another note, say I didn't have the #include "Countries.htm" in test.aspx, is it possible to access the controls within Countries.htm from test.aspx.cs ? (i.e. accessing an external html file controls in cs)

View 3 RepliesI am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value.
The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well.
I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

View 18 RepliesI am trying to save html table to sql server table with unique name and save its data in a database. For example, I have a html table like this(it is dynamically created in browser by user).
I use asp.net, C#, Sql Server 2008 express.How can after clicking on save button, create table with unique name, 2 colums int and varchar(40) types, and insert data?
I think it is possible by rendering table to XML, and then work this xml on C# classes, then save in database.
What you sing about it?
[Code]....
The idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?

I was able to acces an HTML element from my c# code this way:
Page.Request.Form["Name"].ToString(), where name was an html element:
<input id="Name" style="z-index: 102;" type="file">
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?

View 2 Repliesaccessing a table on a page's masterpage.
So I have a sitemaster page and I am getting header and footer controls from it. But for a perticular page I would like not to show the footer and just the header.
Therefore, I am trying to access the master page table control with id "footer".
What I have tried and they all didnt work. First I tried,
Dim ptrMaster As MasterPage = Page.Master
ptrMaster.FindControl("footer").Visible = False
This gives me a null pointer error.
Then I tried to put in a accessor method on the site.master (masterpage) itself.
Public Sub HideFooter()
Me.Controls("footer").Visible = False
End Sub
But the problem here is when I create a masterpage object on the page that I would like to not show the footer. I cant see the method. So if I do
Dim ptrMaster As MasterPage = Page.Master
ptrMaster.HideFooter()
HideFooter doesnt show up as a method.
does anyone know how to access a webpart using the HTML Document Object Model? for example: for a given page which contains a webpart manager and a webpartzone.
[Code]....
I cant access the custom control using the HTML DOM Like this: HtmlDocument doc = HtmlPage.Document;
HtmlElement element = doc.GetElementById("HostTest");
HtmlElement element1 = doc.GetElementById("silverlightControlHost");
HtmlElement element2 = doc.GetElementById("WebPartZone3");
HtmlElement element2Parent = element2.Parent;
HtmlElement element3 = doc.GetElementById("SLRoomConsumerPart1"); //element3 does not return anything at all just Null!
all of the other elements are returned except for element 3 which returns a null! Any controls (regardless if it is a custom control, ASP control, Usercontrol . i tried it by replaceing the custome control with an aspnet button. i go t a null value as well) placed in the <ZoneTemplate> Tag of the <WebpartZone> is not returned using the HTML DOM. I find this stupid and pointless, as the whole point of a webPart is that you can place all sorts of controls in it :
customcontrols, usercontrols html controls, html server controls, aspnet controls and you cant seem to get access to those controls using the HTML DOM model in codeBehind
<asp:WebPartZone ID="WebPartZone3" runat="server" Height="90%" Width="
<ZoneTemplate>
<cc1:SLRoomConsumerPart ID="SLRoomConsumerPart1" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
HtmlDocument doc = HtmlPage.Document;
HtmlElement my_WeBpart_Element = doc.GetElementbyId("myCustomWebPartControl1")
can anyone point me to a solution or a work around as i am trying to access the dom from silverlight 3 but should be exactly the same as doing it from the webpart'shosting page's code behind. so that i can reference the controls inside my web part from the code behind of the custom page once i get hold of the webPart Element referece.

my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.
