Forms Data Controls :: 2 Ways To Iterate Thru A Gridview?
Mar 31, 2011I wrote(attempted) a sub to disable all linkbuttons in a column in my GV. It seems code #1 just disables the LB in 1 row only.

I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?
I have a button in a Gridview that updates selections. This works fine.
I made a DropDownlist wich should put the variables "Kursistnummer" and "pcsvar" in a new table.
The button in the Gridview writes the value of "kursistnummer" and the text "pcsvar" in the new table.
But if i call the sub"btnTilmeldPc_Click" i get this error:
Procedure 'LP_KursistEksamenPc' expects parameter '@kursistnummer', which was not supplied Its friday and its a bit hard stuf for me.
I have these procedures:

I have a gridview that displays query results on a reporting page for a "home-grown" CRM application. From the gridview, a link can be clicked which opens a modal window that contains an iframe linked to a "details" page where record specific info can be viewed/altered. On the details page there are 10 or so dropdownlists (ddls) that are bound every time the page is called. The ddls are bound using a method similar to the example below. I am looking for a way top speed things up a bit. The details page could be called 10-20 times in one session and every time the page loads these ddls have to be bound from the same methods but for different records. What are some options for speeding up the load time for this page??

I am using listview which looks like below:
col1 col2 col3
ow1 textbox1 textbox2 textbox3
dropdown1 dropdown2 dropdown3
row2 textbox1 texbox2 textbox3
dropdown1 dropdown2 dropdown3
i.e. I have two rows and three columns in each column I have 1 textbox and 1 dropdownlist.
What I want is this, When a user selects something from dropdownlist , in selectedindexchanged event, I need to check if selected value from the sender dropdownlist is equal to any of the textboxes of the listview.
i.e. in selectedindexchange event of dropdownlist , I need to find all the textboxes of listview and then iterate them to match with selectedvalue.
Previously, I have done this for 1 row only by using namingcontainer but how to find all textboxes of listview .
I have sqldatabase tables.I am reading table data and putting in a tabconatiner(wth tabs containing textbox, checkbox etc) specific to a client. If a client has more than one row i want to iterate through the rows and read each row data. Basically I want to use a button-click to read the next row data at put it in the tabs and so on. I used sqldatareader and a while loop.I can read the data but while loop iterates through the rows and show the last row data / i want to use a button to go to the next row and show data.
SqlDatareader reader=null;
reader=cmd.ExecuteReader();
while(reader.Read())
{
txtboxName.Text=reader["Name"].ToString();
}
protected button_Click(Object sender,EventsArgs e)
{
//I want to read row data in this button click
}
I've got a datatable in a dataset which contains 44 rows. I can iterate through the rows and add the data to a placeholder - it's all there. However, if I bind a control (say a gridview or dropdownlist) to the datatable, all I get is one record (from the "middle" of the table). I get the same result when I create a dataview of the table - one row.
View 4 RepliesI've created a wallboard application to display outstanding support calls for my ICT department. I've bound a number of gridviews to sqldatasources which execute a stored procedure. This is automated via asp.net ajax controls and partially refreshes the page/data every 30 seconds.
At the moment, when the number of records in the gridview goes over 9, the gridview automatically pages and shows the number of pages in the bottom right hand corner. The helpdesk can then VNC to the box which controls the screen and manually click to see what's on the next page.
What I am after is a way to programmatically (using the c# code-behind file) changing the current displayed page after 10/15 seconds or so, obviously if this is possible in the scope of the gridview. I trailed using javascript (and failed at jquery) of scrolling the gridview within a div, however this didn't work as expected.
Can anyone point me in the right example. I can't find anyone else querying this functionality via a quick Google.
Gridview Code:
<asp:GridView ID="GridView1" ShowHeader="False" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
GridLines="None" CellPadding="2" Font-Size="35pt" AllowPaging="True" PageSize="9">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID">
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="ASSIGNEES" HeaderText="ASSIGNEES" SortExpression="ASSIGNEES">
<ItemStyle Width="32%" Wrap="false"/>
</asp:BoundField>
<asp:BoundField DataField="title" HeaderText="title" SortExpression="title">
<ItemStyle Width="53%" Wrap="false"/>
</asp:BoundField>
</Columns>
</asp:GridView>
SqlDataSource Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FPConnectionString %>" SelectCommand="HDMonitoringOutstandingToday" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

just a general design question that I'd like to hear some of your opinions on. I am designing a system for a client, and I'm using GridView' a lot. They need a lot of columns to be displayed in some of these, and I've had to resort to using a panel with a horizontal scrollbar. This presents some issues - keeping track of which row is which is difficult, even with alternating row colours, and it's generally pretty ugly.How have you dealt with these issues before?
View 1 Replieshow to iterate through all the controls in just my Content place holder ? What I'm looking to do is to Enable/Disable all the controls in my Content place holder (WEbControls as well as HTML Controls).
View 2 RepliesWhat are the ways to pass information to a html page which is invoked using Response.Redirect(path);his 'path' refers to a html file in a share path(does not belong to the same project where the asp page resides).for example in my web app project , upon a selectindexchange event (of a postback list) i hav to invoke a html page(from anywhere) which will display the current selected item.
View 1 RepliesI have an asp website, and a dataset with a datatable. When I check I after configuring it it shows all the data. But when I run the code I got an exception System.Data.ConstraintException was unhandled by user code Message="Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I want to figure it out with iterating datarow.

i have 6 textboxes which i want to iterate.
they are however in a TD in a TR in a TABLE in a PANEL etc.
the only way i've figured out to iterate them is in this way:
this.Controls[0].Controls[3].Controls[7].Controls
that's not only errorprone, but also hard to come up with.
but this.FindControl (to find one by name) doesn't work either, does findcontrol also only search in the direct child, and not the whole hierarchie?
so basicly what i'm looking for is to iterate ALL controls in the page, no matter in which level of the hierarchie, to check if it's a textbox.
Have an objectdatasource that I need to iterate through and tally up values in certain catagories how would I do this.In short I need to grab each row check specific fields then increment counters I startted off below trying to use IEnumerable.is this the correct start?
View 4 RepliesI am having a problem. I need to check to see if a row has been displayed once, and if so don't display it again. I have the following code:

This all works perfectly, but displays the body row repeatedly. So i need to add a counter or something to check this and make sure it is only displayed once..
I tried with DISTINCT in the sql but that didn't work, so i think it may be better doing it through iteration? Can this be done?
Does anyone know how I can iterate through textboxes on a usercontrol and put the values into a list. This is what I have tried so far...

I'm trying to figure out some alternate ways of dealing with a smaller subsets of records from a larger set of records. This would be to increase performance and make it easier for the user to navigate, as opposed to trying to navigate a really large unwieldy record set. I know of a few ways a user can select a record from a record set. Selecting from a Grid View, drop down list, list box are some the first ones that come to mind. Another way I've seen, I think it was done with a repeater or User Control, is to list all of the letters in the alphabet as links and then only return the records that correspond to the letter that was selected.
It could also be done to allow the user to search by last name, first letter of the last name or some other similar method. I'm curious if there are any other ways of doing this. Does anyone know any other techniques that would create a better user experience when selecting a record or subset of records from a large record set?
I have a multi section form which the user can jump between sections to complete. Each section has its own validation group associated with it. I want to create a summary page which itterates through each of the validation groups and outputs if it is valid or not by changing an associated text.The problem that I am having is that once one validation group fails validation all subsequent sections also report as failing - presumably as the page.isvalid is still holding the fact that a previous group has failed
View 1 Repliesi m new to asp.net 3.5 linq and dnt worked much on generics.i m using IEnumerable to return set of results.i m binding this IEnumerable type method directly to datagrid source then it works fine.But i dnt knw how to iterate through this collection??Same way i m using List<String> to return columns like this
public List<String> FindImageData()
{
List<String> lst = new List<string> { "" };
ISingleResult<Usp_Patient_Radiology_DisplayResult> imagedata = objimagedata.Usp_Patient_Radiology_Display(p_PatientID);
foreach (Usp_Patient_Radiology_DisplayResult h in imagedata)
{
string Imageid = Convert.ToString(h.ImageId);
string imagefilename = Convert.ToString(h.imagefilename);
string history = Convert.ToString(h.history);
string imagetype = Convert.ToString(h.imagetype);
string oprposundertaken = Convert.ToString(h.oprposundertaken);
string patientposition = Convert.ToString(h.patientposition);
string report = Convert.ToString(h.report);
string xfilmorn = Convert.ToString(h.xfilmorn);
lst = new List<String> {Imageid,imagefilename,history,oprposundertaken,patientposition,report,report,xfilmorn };
}
return lst;
}
but at front end again i dnt knw how to iterate through it.it returns only single row??
with dataset it was quiet easy to navigate but with linq to sql navigation through generic collections is tough.
I have programatically added javascript to HyperLink controls on all pages in my site from the Masterpage as it is served up.
I have a new problem. I have a Masterpage wrapper around html pages without asp.net controls in them. Using the Masterpage, I need to parse through all html hrefs in each page and add javascript to each link if it includes "http" or ".pdf". Can the Masterpage parse the text of each page and programatically change it?
Actually what i am doing in my Data Access Layer dragging store procedure to TestDbml to display records and creating data context instance in BAL to retrieve records and my method in BAL is like this
public IEnumerable display()
{
using (TestDataContext db = new TestDataContext())
{
var display = obj.USP_Actor_View_Speciality(p_UserName, 1);
return display as IEnumerable;
}
Now the problem is that how can i iterate or fetch over the records and display accordingly in my Presentation Layer so that i could return all the field parameteres Like ield1=val.field1,field2=val.field2.
Just for curiosity, i want to know i how many ways we can write the parameters in a querystring. I have encountered the following
