show DataList Item Index when using SqlDataSource?
I am using SqlDataSource to populate <asp:ListBox>.
Sql Select query returns all the Unique city names. Then <asp:Listbox> is populated. Populated listbox looks like
Houston
Dallas
Austin
...
...
But I want to add "Choose City" at index 0 so the listbox look like
Choose City
Houston
Dallas
Austin
I am not allowed to modify select query (otherwise I would have used the UNION in select query)
How to show datalist item details in jquery popup window...
View 1 RepliesThe problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
Below is my datasource and datalist
[Code]....
In my application, I am using DataList. In Item Template I added One GridView and SqlDataSource to populate data in GridView. DataList having one DataKey field, I want to pass this DataKey Value to the SqlDataSource as Parameter.
I tried this by Using Following:
<SelectParameters>
I have a datalist that holds imagebuttons which all link to images stored in a database. When I click on any of the image buttons the datalist enlarges the chosen picture and manages to dothis as the datalist is binded by the uniqueID of the image in the database. So, when I am looking at the enlarged picture, it would be nice to be able to click 'Next' & 'Prev' link buttons to move onto the next or previous picture without having to return to the datalist in between looking at a different photo.
I have managed to set up methods for clicking on 'next' and 'prev' linkbuttons that will successfully browse back and forth between photos in the datalist but the selected index always starts at 0, i.e the first photo in the datalist. So if I'm viewing the 5th image in the list and press 'next', the first image in the list shows up. I thought just by clicking on an image button would automatically set the selected index but obviously this is not the case. I have read various threads and tutorials on the net and a lot of them point to dlIcons.SelectedIndex = e.Item.ItemIndex; I have tried to put this in the itemDataBound method for my datalist but it changes nothing. And if i try to put that line of code in other messages in the class i get error messages (I'm using Visual Web Developer C#).
its part of a final year project due in 3 weeks and by now I should be writing the report! The code I'm using is pretty huge and spread out between classes but I will include what I think might help illustrate how it all works:
<asp:DataList ID="dlIcons" runat="server" DataKeyField="AttachmentID"
OnItemDataBound="dlIcons_ItemDataBound" ItemStyle-BorderWidth="1px"
RepeatColumns="5" RepeatDirection="Horizontal" CssClass="Icons"
OnSelectedIndexChanged="dlIcons_SelectedIndexChanged">
<AlternatingItemStyle CssClass="AlternatingRowStyle" />
<ItemStyle CssClass="RowStyle" BorderWidth="1px" />
<HeaderStyle CssClass="HeadeBrStyle" />
<FooterStyle CssClass="FooterStyle" />
<SelectedItemStyle CssClass="SelectedRowStyle" />
<ItemTemplate>
<asp:Label ID="lblFilename" runat="server" Font-Size="Small"
Text='<%# Eval("Filename") %>' ></asp:Label>
<br />
<asp:LinkButton runat="server" id="btnDelete" CommandArgument="<%# Bind('AttachmentID') %>"
CommandName="DELETE" Text="Delete" OnClick="btnDelete_Click"
Font-Size="small" CssClass="btnDelete" />
<br />
<asp:ImageButton runat="server" ID="imgBtnFileType" width="120" Height="120"
ImageAlign="right" ImageUrl='<%#"http://localhost:49279/PDFViewer/GetAttachment.ashx?AttachmentID=" + Eval("AttachmentId") %>'
OnClick="imgBtnFileType_Click" BorderWidth="1PX" CssClass="imgBtnFileType"
CommandName="VIEW" CommandArgument="<%# Bind('AttachmentID') %>"/>
<br /><br />
</ItemTemplate>
</asp:DataList>
The CS file:
protected void dlIcons_ItemDataBound(object sender, DataListItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
DataRowView drv = e.Item.DataItem as DataRowView;
dlIcons.SelectedIndex = e.Item.ItemIndex;
int attachmentID = (int)drv["AttachmentID"];
string fileType = (string)drv["Type"];
ImageButton imgBtnFileType = e.Item.FindControl("imgBtnFileType") as ImageButton;
string fileName = (string)drv["FileName"];
Label lblFilename = e.Item.FindControl("lblFilename") as Label;
lblFilename.Text = fileName.Length > 12 ? fileName.Substring(0, 10) + ".." : fileName;
}
}
The next and prev link buttons onclick leads to these two methods:
public int nextPic()
{
dlIcons.Items.Equals(dlIcons.SelectedIndex++);
int nextAttach = (int)dlIcons.SelectedValue;
return nextAttach;
}
public int prevPic()
{
dlIcons.Items.Equals(dlIcons.SelectedIndex--);
int prevAttach = (int)dlIcons.SelectedValue;
return prevAttach;
}
these were void methods but i've been stuck on this for hours and have resorted to fiddling with just about everything.

View 2 RepliesI've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

i have 3 items in my dataliste but the
Label46.Text = DataList2.Items.Count gives me 2.
I'm trying to figure out how can I control my linkbutton which nests inside my DataItem in the ItemTemplate.What I wish to do is to check something in the server side and according to that, decide whether I wish to alter its visibility to "true" or to keep it hidden. I think that the method which is going to solve it is the ItemCreated, although, I don't happen to know how to control that specific item of mine.

here's my issue:I want to delete an item from a datalist and i cant seem to get it working. I am using the delete code from a sqldatasource which is..
[Code]....
I have searched on the web for code for this, but all i can find is code to delete the primary key from from a table. My issues is that i have a double primary key.The way that it works is, i insert a load of data, but which uses number1 as the first primary key, and number 2 is like an item of number1 as such.Sorry about the explanation, if you dont understand i'd happily try and explain it better.
I have a data list , each row consist only from button , i want to retrive data from data base depending on the item, I mean each button or row have different tooltip , it is possible to do this ?
if the button is enable=false also it is possible ?
i don't know english very well sorry about that and my question isi have datalist in my web page like this
<div style="height: 550px;">
I have the following line to display a piece of data and I want to know how I can format the output.
Text='<%# Eval("DOH") %>'
The data list displays the correct data, but I want to format it. The output I want is just a small date format instead of date and time. I have tried every combination of a format function I can think of, but can't seem to make it work. Am I stuck with the raw format provided by the database? I wouldn't think so, but maybe that is the case.
expected output should be 02/15/2011 instead of 02/15/2011 09:45:
I am using the following code with a datalist, but how can I change the date format of the PublicationAddDate Field, it is not displaying as expected, even though it is in the correct format in my DB.

i am making a site like linkedini have a datalist which show the search of peoples from database. my problem is that, i have mixed data to show in datalist.suppose datalist going to show only 2 label values, first is "who" second is "type". who can be of 4 types just like linkedin search, "A student","employ",Bussiness owner", "working independent"when student is pick in one label from database then college will be display in second labelwhen employ is pick in one label then company will be display in second column.It means i cannot bind the second label at designtime. and even at run time i have to bind each item of second label with approprite to first label. bec search can be mixed, means if 10 peoples are searched, then may be someone is employ, someone is student, and second label should show value appropriate their first label.
