Hai,
How to add a selected listbox data into another listbox
|
|
|
|
|
In Listbox you are having a Items.Add method using which you can add the selected items of the previous listbox.

Hi,
I'm facing one of the issue discussed in this article. I've created a user control with a DataGrid on it. I've created properties to make this control visible, and to set the connection information for database.
I'm doing all these in the Page_Load event of that user control. In the main form where i'm using this control, I have a button that I use to make this control visible. During Page load of main page, I make the user control visible false, and only when the user clicks the button its made visible.
But the problem is that before the button click event of the main form, the page_load of the user control is getting fired (as discussed in ur article).. What can I do now?
Regards,
Blumen

This is not an article, it's a programming forum. Page load is called before events. Always. Put it in your prerender, if you want it to fire after the button click.
There's a forum in the article, if you want to ask an author something

Ok, I'll try it in Prerender event.
Sorry about the "article" reference in my message.

In my page there are two textboxes to enter dates. FromDate and ToDate textboxes. The difference between FromDate and ToDate should not be geater than 31 days. and also make sure FromDate should be less than ToDate. How to validate on client side. Am using asp.net 2.0 and c#.
Can anyone give solution?
Thanks in advance.

You can use calendar to avoid basic date validation. But if you are using simple text box to get the date then Here[^] you can get so much help.

Hello Guys.
This is just about my first post on here.
My problem on which i need some help on is as follows:
I have no problem invoking the edititemtemplate on a (Not nested) datalist.
But once i try invoking it on a nested datalist nothing happens, i have assured
that my edit button event fires. But the edititemtemplate never gets rendered.
Below you'll find a snippet of my aspx file:
<asp:DataList
ID="HeadlinesDataList"
runat="server"
OnItemDataBound="HeadlinesDataList_ItemDataBound"
DataKeyField="headlineID"
OnEditCommand="HeadlinesDataList_EditCommand"
OnCancelCommand="HeadlinesDataList_CancelCommand"
OnUpdateCommand="HeadlinesDataList_UpdateCommand">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "headlineName") %>
<asp:LinkButton ID="EditHeadlineButton" runat="server" CommandName="Edit">[Edit]</asp:LinkButton><br />
!--Categories-->
<asp:DataList
ID="CategoriesDataList"
runat="server"
DataKeyField="categoryID"
OnEditCommand="CategoriesDataList_EditCommand">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "CategoryName") %>
<asp:LinkButton ID="EditCategoryButton" runat="server" CommandName="Edit">[Edit]</asp:LinkButton><br />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="CategoryName" runat="server" Text='<%# DataBinder.Eval Container.DataItem, "categoryName") %>'></asp:TextBox>
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="Cancel">[Cancel]</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Update">[Update]</asp:LinkButton>
</EditItemTemplate>
</asp:DataList>
<!--/Categories-->
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="HeadLineName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "headlineName") %>'></asp:TextBox>
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="Cancel">[Cancel]</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Update">[Update]</asp:LinkButton>
</EditItemTemplate>
</asp:DataList>
<!--/Headlines-->
And here you'll see my code file for the aspx, My edit button on the nested datalist invokes this method:
CategoriesDataList_EditCommand

}

myHeadlines.UpdateHeadlineName((int)HeadlinesDataList.DataKeys[e.Item.ItemIndex], HeadLineName.Text);
HeadLinesDatabind();
}
}
Okay i hope somebody can give me some help.. I'm just about to give up on this.
BTW: I'm coding in Visual Web Developer 2005 Express Edition.

Hi,
ok here is the scenario:
I have two pages Transactions and Points. In the Transactions Page, I have an amount field. I was trying to pass on 10% of that amount to the Points page and directly set it in the Points Field.
I have tried several stuff. with some web help but it didn't work. I think what it is trying to do is open the page with a filter given the points= 10 example.
Please help 
Thanks a lot
IssamK

how you are opening the Points page?
If you are opening it in a new window using javascript then you can pass it in querystring or you can access the field in transaction page using opener.document.getElementById(amountfield).
And if you are redirecting it from server side using response.redirect or server.transfer then you can keep it in session before redirecting and access it from session in Points page.

Ok guys,
i am not very much aware of this code, i am just kinda debugging.
what is interesting to mention is this:
<smartone:themebutton runat="server" id="SaveButton" button-causesvalidation="True" button-commandname="UpdateData" <b="">Button-RedirectURL="Mypage.aspx?Points={TransactionRecordControl:FV:Amount}"
does it help?
thanks.

here is the straight forward code.
in transaction.aspx add a button like:
<br />
<asp:button id="btn" runat="server" onclick="redirectToPoints" text="Open Points Page" /><br />
in code behind file for transaction.aspx.cs do this:
<br />
protected void redirectToPoints(object sender, EventArgs e)<br />
{<br />
Session["tranAmount"] = youramount;
Response.Redirect("points.aspx",true);<br />
}<br />
in PageLoad function in code behind file for points.aspx.cs do this:
<br />
protected void PageLoad(object sender, EventArgs e)<br />
{<br />
if(!IsPostBack)<br />
{<br />
textboxPoints.Text = Session["tranAmount"].ToString(); <br />
}<br />
}<br />

Don't cross post it makes you rather unpopular.

hi,
well what you could try and do is to use the charAt(0) functionality of each field. and set it to upper case.
am not a pro, however this is a primitive sample code for a form with two textboxes and a button.
Dim a As String
a = TextBox1.Text
Dim b As String
b = a.Chars(0)
b = b.ToUpper()
Dim c As String
c = b & a.Substring(1, a.Length() - 1)
TextBox2.Text = c
Good luck...

I have been trying this for ages but it just doesn't seem to work. I have an image control inside a repeater control. the image control is bound to an image using the image url and databinding this when all information is called:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<HeaderTemplate>
<h2><asp:Label ID="lbl_title" runat="server">T.R.E.E Team</asp:Label></h2>
</HeaderTemplate>
<ItemTemplate>
<div class="story">
<p>
<h1><asp:Label ID="lbl_Role" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Role")%></asp:Label></h1><br />
<asp:Image ID="image_role" ImageUrl="%#DataBinder.Eval(Container.DataItem, "Team_Name")%" runat="server" />
<asp:Label ID="lbl_Name" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Name")%></asp:Label><br />
<asp:Label ID="lbl_Description" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Description")%></asp:Label><br />
<asp:Label ID="lbl_Telephone" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Telephone")%></asp:Label><br />
<asp:Label ID="lbl_Email" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Email")%></asp:Label><br />
</p>
</div>
</ItemTemplate>
</asp:Repeater>
I am using the new visual web developer 2008. If anyone knows why this is not working please let me know.

you have this line:
<asp:Image ID="image_role" ImageUrl="%#DataBinder.Eval(Container.DataItem, "Team_Name")%" runat="server" />
change it with this one and it should work:
<asp:Image ID="image_role" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "Team_Name")%>' runat="server" />
you were using % instead of <% and " instead of '

Can you double check my syntax on this? I keep getting an error of too many literals in the string
ScnQuestionNo and MeasID are number fields
<br />
string strInsert ="Insert INTO DataElements (Checked, Requirement, RequirementTitle," + <br />
" MeasID,DeNr, Duplicate, LiveQuestionNo, ScnQuestionNo, DataElement, Form, QType," +<br />
" Format, [Default], SME, [User], SA, IASME, Security, [Table], FieldName," + <br />
" TQScenario, TQLive, Subtitle, DA) Values (" + Convert.ToInt16(ckChecked.Checked) + ",'" + Requirement.Text + "','" +RequirementTitle.Text+ "'," + MeasID.Text + ",'" + DeNr.Text + "'," + Convert.ToInt16(ckDuplicate.Checked) + ",'" + LiveQuestionNo.Text + "'," + ScnQuestionNo.Text + ",'" + DataElement.Text + "','" + Form.SelectedValue + "','" + QType.SelectedValue + "','" + Format.Text + "','" + Default.Text + "'," + Convert.ToInt16(ckSME.Checked) + "," + Convert.ToInt16(ckUser.Checked) + "," + Convert.ToInt16(ckSA.Checked) + "," + Convert.ToInt16(ckIASME.Checked) + "," + Convert.ToInt16(ckSecurity.Checked) + ",'" + TableName.SelectedValue + "','" + FieldName.Text + "'," + Convert.ToInt16(ckTQScenario.Checked) + "," + Convert.ToInt16(ckTQLive.Checked) + ",'" + Subtitle.Text + "'," + Convert.ToInt16(ckDA.Checked) + ")";<br />
<br />
<br />
Here's my debug output:
strInsert: "Insert INTO DataElements (Checked, Requirement, RequirementTitle, MeasID,DeNr, Duplicate, LiveQuestionNo, ScnQuestionNo, DataElement, Form, QType, Format, [Default], SME, [User], SA, IASME, Security, [Table], FieldName, TQScenario, TQLive, Subtitle, DA) Values (0,'Unk','Unk',,'DE 0.1.17',0,'',,'Last four digits of SSN','Demographics','N/A','char','',0,0,0,0,0,'Demographics','LastFour',0,0,'N/A',0)"
Now I get "Line 1: Incorrect syntax near ','."

Whoah - that is one really insecure statement. Have you considered what this is going to do if you become the victim of a Sql Injection Attack[^]? Please reconsider before you go any further down this path.
