i was able to add a table dynamically to my form.[URL]
Now i need to grab the values and insert into the database. Below is the code used to create the table when a selection is made from a dropdown. My insert expects 3 parameters, ID, CamID, CamName
The ID will be from a field in the form, the CamID needs to be the "j" value below and the Camname to be the txtcam value.

I am dynamically generating the Row in GridView and saving the data in database using StringCollection. Instead of using StringCollection i want to pass the data(user entered data) to local variable , eg:
string name = txtFName; and so on. but it wont work for dynamically created rows.
So if you knw how to assign the user provided data in the local variable like above i have show.
The code for inserting the records for dynamic created rows in grid view via StringCollection is below
protected void btnSave_Click(object sender, EventArgs e)
{
int rowIndex = 0;
StringCollection sc = new StringCollection();

I have Dynamically generated HTML Table which has dynamically generated button in one of its column. If that button is clicked it adds a textbox to the very next row using javascript.I encountered a problem in identifying which column's button is being clicked.Please someone help me how to get the particular row index of a table of which button is being clicked. And how to send that rowindex to the javascript function which generates the textboxes.
View 2 RepliesI have an application that is supposed to accept checks. The user has 2 radio buttons. The first radio button has a drop down list associated with it which contains the masked numbers of their previously used checking accounts.
The second radio button has three text boxes and an image of a check associated with it.
When a user hits this page, the three text boxes and the check image associated with the second radio button are disabled. Then, if the user decides he/she wants to use a new checking account, they can click the second radio button and that fires the Javascript that enables the three check boxes and the image of the check associated with that second radio button. If they click on the first radio button, it will re-disable the text boxes and hide the check image associated with the second radio button.
The problem happens when I do my server side validation. After validating all text fields, if there is a problem, I just fall out of the bottom of the code, the page posts back and the labels above the offending text fields show an error message.
One caveat: The Javascript that is supposed to fire on the OnClick event for the first radio button fires and the text fields for the second radio button are disabled. The user can click on the second radio button and the fields will enable, but this is very clunky.
Here's the enable code where I am injecting the Javascript:
Private Sub JavascriptInject()
Dim sEnableControls As String
Dim sDisableControls As String

View 2 RepliesI'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
I have a page with a datalist on it, with an image button and some labels in the datalist item(1,2)..
I have some more labels on the page which get their values from querystrings(17,18)..
I have more labels which are empty (34,35)
On image click in the datalist item, i want the labels from that item to add with the labels outside of the datalist, and the last lot of labels to show this number..
Currently it doesnt do this. Here is my code:
protected void Page_Load(object sender, EventArgs e)
{
Label17.Text = Request["b1"];
Label18.Text = Request["b2"];
}
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
DataListItem item = ((Control)sender).NamingContainer as DataListItem;
Label Label1 = item.FindControl("Label1") as Label;
Label Label2 = item.FindControl("Label2") as Label;
Label34.Text = (int.Parse(Label1.Text) + int.Parse(Label17.Text)).ToString();
Label35.Text = (int.Parse(Label2.Text) + int.Parse(Label18.Text)).ToString();
What I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page.
And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image.
So how can I make these labels stick to the Panel and not the Page? How do I do it?
Referred to your previous article of Dynamically creating textbox . Now i want to add labell also with them
Till now my code
protected void Page_Init(object sender, EventArgs e)
{
List<string> keys = Request.Form.AllKeys.Where(key => key.Contains("txtDynamic")).ToList();
List<string> labelkeys = Request.Form.AllKeys.Where(lkey => lkey.Contains("labeltxt")).ToList();
int i = 1;
foreach (string key in keys)

Textbox are generating as i press button but label generate once than it doesnt.I debugged it i am getting count 0 in label
I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
When i don't create them dynamically like
<asp:TextBox ID= "TextBox1" name="TextBox1"> </asp:TextBox>
I can get the value from the C# side by using the
((TextBox)Page.Form.FindControl("TextBox1")).Text
However this moethod doesn't work for the textboxes that i created dynamically. I'm creating them in a loop it's something like;
[Code]....
Then i add the text box to the necessary places at my table.However i can't reach the textboxes when i use the same method
((TextBox)Page.Form.FindControl("!A uniqe ID!"));
It gave a null value...

I have a web user control with dynamic LinkButton think an event in which you assign events to them (LinkButton.Click + = new EventHandler (Method)).The problem is that these events do not run, I did test creating and if you run statically.Why is it??I need to be created dynamically at runtime.For Examples :
for (int i = 0; i <= 5; i++)
{
Button boton = new Button();

View 2 RepliesI have a link button let's say LB1 wherein on click of the LB1 a modalpopupextendar will open up with a textbox where we can enter the message and onclick of Ok button the entered message will be saved. Let's say we have repeated the above steps for thrice. So there will be three rows created in DB. Let's say column name UID is the primary key.Now, I am displaying the each message inside a panel along with Link Button(LB2) which is created dynamically while reading the text. So,The first row will contain
UID:1 Message:Message1
Comments:Comments Link Button(LB2)
The second row will contain
UID:2 Message:Message2
Comments:Comments Link Button(LB2)
The third row will contain
UID:3 Message:Message3
Comments:Comments Link Button(LB2)
When I click on Comments Link Button(LB2) a modalpopupextendar will popup wherein we can enter the comments. Let's say we are clicking on LinkButton of Message 1, a pop up opens and after entering comments and ok button the comments are saved for all the three messages instead of saving it for message 1, i.e I couldn't find the unique id of the message.
A short background about this project: I'm creating an image gallery where images are uploaded and sorted into a category and then a subcategory, eg. "Vehicles" and "Cars". Every subcategory has a variety of tags to further categorize the picture, eg. color and make in the cars subcategory.
These tags (named "Criterias") are listed as DropDownLists through the following piece of code:

My problem now is that I can't figure out how to loop through them to find what criteria values to tag the image with.
I have the following code to generate a table with the necessary textboxes. Now i need to populate those fields with the data from the table. If it makes it any easier, the individual textbox values are stored in a table with a reference to the main recordID

I need to create web controls (e.g. label etc) dynamically.The problem is that for example,
on my onload event, I create a label. The text of the label is read from one line of a xml file.
But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:
Message (<#% MessageCount %>) instead of Message (4 ).

I'm writing a code for a custom webpart that will retrieve data via data reader or data set (not sure which is better). In the code I will separate data into 4 categories (always just 4). Each category of data will be displayed in a tab panel, so a total of 4 tabs in the tab container. All of this is created dynamically in the CreateChildControls() method. So far I have it working for with one tab and I don't know how to separate the data into the 4 tabs.
Here the what I've got so far (simplified for posting):
_dr = bll.drGetData(id);
Panel panel1 = new Panel();
while (_dr.Read()){
DataList dl = new DataList();
NOTE: This is where I think I need to branch off the data into the 4 categories but I'm not sure how to implement it.
dl.ItemTemplate = new MyTemplate(LIstItemType.Item);
dl.DataSource = _dr;
dl.DataBind();
panel1.Controls.Add(dl);
AjaxControlToolKit.TabPanel tp = new AjaxcontrolToolkit.TabPanel();
tp.Controls.Add(panel1);
TabContainer tc = new TabContainer();
tc.Tabs.Add(tp);
this.Controls.Add(tp);
public class MyTemplate : ITemplate{
ListItemType _itemType;
public MyTemplate(ListItemtype Type){_itemType = Type;}
pubilc void InstatiateIn(System.Web.UI.Control container){
LinkButton linkb1 = new LinkButton();
linkb.DataBinding += new EventHandler(TemplateControl_DataBinding);
container.Controls.Add(linkb); }
private void TemplateControl_DataBinding(object sender, System.EventArgs e){
LinkButton linkb = new LinkButton();
linkb = (LinkButton)sender;
DataListItem container = (DataLIstItem)linkb.NamingContainer;
if(Convert.ToInt32(DataBinder.Eval(container.DataItem, "id")) >= 1) {
NOTE: Although here is where the databinding takes place so I woud assume the categorization the data can take place here as well but I dont see how.
linkb.Text = ...
linkb.CommnadArgument = ...
etc...
}
