Hi All
I have a requirement where, i created a repeater control and a link button is present in the repeater control. On clicking the link button i want to display child repeater control and bind data to it.
The child control should have the same look as the parent repeater control. It means, the child control has a link button and again on clicking the linkbutton one more child control chould be created.
The code is as below.
<
table width="100%" border="0" cellpadding="0" cellspacing="0" >
<tbody>
<tr>
<td>
<asp:Repeater ID="repeaterreply" runat="server" OnItemCommand="Repeater1_ItemCommand">
<ItemTemplate>
<table width="100%" border="0" cellpadding="0" cellspacing="0" >
<tbody>
<tr >
<td class="tdmain">
Posted On:
<asp:Label ID="lblPostedOn" CssClass="txt" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "DatePosted")%>' />
</td>
</tr>
<tr >
<td>
<table width="100%" border="0" cellpadding="1" cellspacing="1" class="tableborder1">
<tbody>
<tr class="tdrow1">
<td width="25%" valign="top">
<%
# DataBinder.Eval(Container.DataItem, "EmployeeName")%> <br /><br />
</td>
<td width="65%">
<asp:Label ID="lblrpl" CssClass="txt" runat="server" Text= '<%# DataBinder.Eval(Container.DataItem,"ArticleText") %>' /> <br />
<asp:LinkButton ID="lnkrply" runat="server" Text="View Replies" CommandName="click" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"ArticleDetailID") %>' />
</td>
<td width="5%" valign="bottom">
<IMG id="img1" height="16" src="../Images/wp_up.gif" width="16" onclick="javascript:reply_show();"
onmouseover="javascript:img1.style.cursor='hand'"/>
</td>
</tr>
</tbody>
</table>
<asp:Panel ID = "literal" runat="server" />
</td>
</tr>
</tbody>
</table>
</ItemTemplate>
</asp:Repeater>
</td>
</tr>
</tbody>

In MVC , we create a business object that represents a table fields may be with the same column names or with other names then create public properties to get and set those values .
that is totally fine until now .
then i want to display that Object in a grid , i will assign the datasource property to a ILIST,Ienumerable,IDataSource object like for example List< of One business objects > then the grid will iterate through the collection of objects getting every object and accessing the properties names that will reflect the column names in the grid , and the values of those properties will be assigned to the column values in the grid
like for example
// we have this business object
public class Customer
{
string FName;
string LName;
public string FirstName
{
get { return this.FName;}
set { this.FName = value;}
}
public string LastName
{
get { return this.LName;}
set { this.LName = value;}
}
}
now to display that class to the grid i will put it into a list for example then
the grid will iterate through the list , reading each object public properties to draw the column names
the grid will have the same column names like the public properties
then accessing these properties values to display it to the grid .
i need to make a business object to be displayed in the grid but the problem is that the business object in my task doesn't have public properties , the public properties are replaced with a data structure that reads the table schema , "Generic Business Object" that is modifiable according to the table schema inside the data base
but finally i need to display each Generic Object to the data source controls like grid

hello friends,
In my application i am having a usercontrol py_user, now i want to create its multiple instance at runtime, like if i enter 5, 5 py_use control should be added on the page.
Please help me how to do this.
|
|

What I think you're asking for is creating your py_user control dynamically, when certain conditions are met, and also, a specified number of times, which would be user-input defined.
I'm only guessing you'll be putting that number in a textbox somewhere on your page.
Either way, how you should be doing it, is:
private void CreatePyUser()
{
try
{
int pyNum = Convert.ToInt32(textBox1.Text);
for(int py_uNum=0; py_uNum<=pyNum; pu_uNum++)
{
py_user py_user1 = new py_user();
py_user1.ID = "py_user"+py_uNum.ToString();
this.Controls.Add(py_user1);
}
}
catch
{
Response.Write("Please put in a number in the given textbox.");
}
}
If that's not what you wanted, please try explaining what you need in a bit more detail.
And perhaps pass some of your own code, sometimes?
var question = (_2b || !(_2b));

Thanks for your quick reply but i am not able to make an object of the usercontrol ie py_user py_user1 = new py_user();
also this part i have done using
Control t = LoadControl("../UserControl/py_user.ascx");
t.ID = "py" + i.ToString();
pPanel1.Controls.Add(t);
In my user control there is a textbox that takes an integer value and generates a table with the specified no of rows,
Now what happens suppose i have created 3 instance of my usercontrol, again in the first usercontrol i want 3 rows so i put 3 and generate 3 rows till this it is working fine, but when i move to second instance of usercontrol and try to generate 2 rows it generate 2 rows but it clear the rows of first control.
i want rows in all the usercontrols, please help me..............
|
|
|
|
|
I think I know what you mean...
As I understand it, you have something like this, in the code-behind of your usercontrol:
private void CreateTable(int x)
{
HtmlTable table = new HtmlTable();
for (int y = 0; y <= x; y++)
{
HtmlTableRow tableRow = new HtmlTableRow();
table.Controls.Add(tableRow);
}
this.Controls.Add(table);
}
And this method gets called through some button click on the user control.
This is only going to govern this instance of your py_user. It will do a postback and render a table FOR THIS instance. But the remaining 4, or however many py_user controls on that page will not have had that buttonclick triggered for them and therefore they would get rendered as PURE py_user controls (no tables, no rows), if at all.
I don't like your design one bit.
Sorry there is no easy way out, without adding those controls to the Session, then checking if the session is not null.
Honestly, what are you trying to achieve through this?

We are designing an application in which a large number of forms with predefiend text have to be presented to the user and the user has to fill in the desired values and post it back to the application. The following 2 solutions are there in my mind :
1. We could have used directly pdf in browser and get the user entered data posted back to the application for processing.
2. Adobe Forms Server (but the S/W is not with me so can't decide on it)
The primary requirements are :
1. The user should be presented with the form in the way he should be able to print it.
2. We need to have control on whether the user can save/print the form or he cannot do so.
3. There may be a need for the form to be presented back to the user at a later stage, with the data filled in by him through an application generated ID.
Thanks,
Sundeep

I'm sorry. Is there a question in there?
As much as it pains me to say this, have you tried InfoPath?
I didn't get any requirements for the signature

Thanks for your reply.
My question is what would be the best approach in such a scenario?
I am aware of only these 2 options mentioned by me :
1. We could have used directly pdf in browser and get the user entered data posted back to the application for processing.
2. Adobe Forms Server (but the S/W is not with me so can't decide on it)
In the first one I am not aware of how I can control the toolbars display for achieving the flexibility to programatically decide is the save / print options are to be encabled or not.
As for the second one, I have formed my understanding on the basis of whatever I have read, but have never used it and since I don't have this S/W so can't clearly decide if that will be the recommended solution.
Of these 2 approaches is there a better approach also?
Also for option 1 , how can I achieve the flexibity that is required ?
I have not used InfoPath..

Hello all,
I am searching for control which control is more faster to display data from database.
currently I am using repeater control and data grid view.
and some time I get data with help SqlCommand and Sql addapter I though it is more fast.
If I create a custom control and use response.Write it will fast?
If you have any suggestion than please share with me.
Regards

Data Adapters are slow, databinding is slow, data binding using DataBinder.Eval is really slow.
Get the data via a Data Reader, stuff it into a custom object, and then render the page using a repeater control without using DataBinder.Eval and I think you will notice a fair, maintainable improvement.
Also, how much data are you trying to display? Retrieve the smallest amount possible for the given screen and rendering only the required elements is another avenue for speed improvements.

Your main bottleneck will probably not be the repeater, response.write or gridview.
If you can, cache the data. I wrote an article with an easy way to do that http://www.codeproject.com/KB/aspnet/LookUpDataCache.aspx[^]
You main bottleneck will probably be the SQL query, not the serialization of the data.
Also, if you use the repeater or gridview's itemdatabound event that will be faster than setting the data in the mark up. Because the mark up has to use reflection to get the data type.

Text="Execute"/>
function openwindow()
{
window.open("AssignedTickets.aspx",'window','width=630,height=620,background=silver,menubar=no, resizable=no')
}
And I want to pass parameters to that popup page because there are some search parameters i need to pass those to popup page and display the results in popup page.
Please anybody help me how pass parameters using javascript.
Thanks in Advance

Adding parameters to the querystring would be a clean way of doing it, though it has its disadvantages.
Do:
function openwindow()
{
window.open("AssignedTickets.aspx?Param1=Something¶m2=somethingother",'window','width=630,height=620,background=silver,menubar=no, resizable=no')
}
Then in the code behind of AssignedTickets you can access these with:
string param1 = Request.QueryString["param1"];
var question = (_2b || !(_2b));

thanks for your response. I am trying with that code. But my values are in textboxes. can you tll me exact syntax to assign textbox values to param1 ans param2?
|
|
|
|
|
Oh, man...
var param1 = document.getElementById('textBox1').value;
obviously it doesnt have to be called param1.
Please read up on javascript, seems like you need it.
Good luck.
var question = (_2b || !(_2b));
|
|
|
|
|
I used this statement to pass values
var param1 = document.getElementById('textBox1').value;
but it dost not passing anything i am getting null value.
|
|
|
|
|
Oh, come on.
it's not my fault your control does not have any text in it.
Where are you declaring the param1 variable, anyway?
Where are you accessing it from?
Is your control's ID textBox1 ?
Either put some more code out here or google for it and figure it out yourself.
I really do recommend the latter, too.
