My list box contains 2000 items and the index is not able to set the focus if the index > 820
would like to build a chart that will focus on the point plot. which mean every first point index is plotted will show in the chart as more and more chart plotted those point already been plotted will move to the back of the chart so the user only see the latest point is plot in the chart,anyone try this before in mschart ? can we add scrollbar, slide show or something for user to view the past plotted chart ?
View 4 RepliesI have made a chat application which is working fine but to refresh the text messages which is seen by user 1 and input by user 2 I have used timer.Timer periodically updates messages and ScriptManger1.SetFocus(TextBox1.ClientID) sets the focus but.. when I do so ,user 1 (if) inputting text watches message box being repopulated but at the same time all the text he wrote in yet to send textbox text is washed away!!!So how can we set focus at the end of the textbox text?
View 2 RepliesI have a listbox which populated from using a datatable. I have a Add button in my page. On clicking the add button I want to insert a blank row in the listbox. This can be done easily by
ListBox_Admin.Items.Add("");
after this is done I want to select this item as in setfocus on this item.How do I do this.
I have a gridview with edit functionality and using the EditItemTemplate section. I am trying to set focus to a textbox when user selects the edit mode.
[Code].....
Asp.NET v2.0
Data grid with mulitple texboxes per row.
Each textbox has a TextChange() event wired up for data validation.
These events fire just fine, the data validation works just fine.
My issue is this: User enters text into TextBox1 one then tabs into TextBox2. The cursor appears for a split second inside of TextBox2 then disappears as focus is being set somewhere else on the page. I'm not sure how that change of focus is happening.
In this scenario, after tabbing out of TextBox1, how can I maintain focus on TextBox2 (and then subsequently TextBox3, TextBox4,etc..)
I have a listBox that is bounds its content from the database. This control is inside an itemTemplate. When the item template is boudned, I want to select the corresponding value.
I have this ugly single line of code:
[Code]....
What it does is to select the right value to a ListBox that is databinded with values inside a DetailsView
here is the rest of the code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource4"
EnableModelValidation="True" ondatabound="DetailsView1_DataBound">
<Fields><asp:TemplateField><ItemTemplate>
<asp:ListBox ID="lbATechAuthCheck" runat="server" Width="100%" DataSourceID="SqlDataSource2" DataTextField="status" DataValueField="id"></asp:ListBox><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString
%>"SelectCommand="SELECT * FROM [Status]"></asp:SqlDataSource>
</ItemTemplate></asp:TemplateField></Fields></asp:DetailsView>
Is there an easier way to achieve the same thing perhaps without any code behind?
In Listbox after select one item in first and how to unselect or remove focus on that listbox.
View 1 RepliesI have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true);
list.DataSource = (from ap in edc.Approvers
where ! ap.approverEmail.Equals("")
orderby ap.approverEmail
select new {ap.approverEmail}).Distinct();
list.DataTextField = "approverEmail";
list.DataValueField = "approverEmail";
list.DataBind();
list.Items.Add(li);
list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.
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.
I have been browing forums & googling for a couple of hours this morning, trying to find an answer to what (to me) should be a very simple issue. (I am a Delphi programmer moving somewhat reluctantly to Visual Studio C# , for web apps) I have created the simplest ASP.NET website in Visual Studio, containing a Textbox and a Button. When the website loads, I want Textbox1 to have focus. Simply doing
[Code]....
and this too does not work. However, if I press the Enter key when the webpage is displayed, then focus does move to TextBox1 (and pressing Enter again will fire any code attached to Button1). Surely it cannot be this hard to perform something so simple?
I am having 3 ListBoxs(LB1,LB2,LB3).In LB1 I am binding the names of Courses through database.The code is shon below...
da1 = new SqlDataAdapter("SELECT COURSE_ID,COURSE_NAME FROM Course_Mst", con);
DataTable dt1 = new DataTable();
da1.Fill(dt1);
lstCourse.DataSource = dt1;
lstCourse.DataValueField = "COURSE_ID";
lstCourse.DataTextField = "COURSE_NAME";
lstCourse.DataBind();
Whenever I select particular course in LB1 all the content related to that course will be binded in LB2.The code is shown below.....
protected void LB1_SelectedIndexChanged(object sender, EventArgs e)
{
da2 = new SqlDataAdapter("SELECT SPEC_ID,SPEC_NAME FROM SPEC_TRANS WHERE COURSE_ID="+Convert.ToInt32(lstCourse.SelectedValue)+"", con);
DataTable dt = new DataTable();
da2.Fill(dt);
lstSpecilization.DataSource = dt;
lstSpecilization.DataValueField = "SPEC_ID";
lstSpecilization.DataTextField = "SPEC_NAME";
lstSpecilization.DataBind();
lstSpecilization.Focus();
}
I am having a ADD button.In LB2 I can select multiple items.When I select multiple items in LB2 and click on ADD all the selected items will be binded into LB3.The code is shown below...
protected void btnAddCourseDetaisl_Click(object sender, EventArgs e)
{
for (int intLoopIndex = 0; intLoopIndex <lstSpecilization.Items.Count ; intLoopIndex++)
{
if (lstSpecilization.Items[intLoopIndex].Selected)
{
ListItem li = new ListItem(lstSpecilization.Items[intLoopIndex].Text, lstSpecilization.Items[intLoopIndex].Value);
LB3.Items.Add(li);
}
}
}
My problem is when I select a item from LB2 and click on ADD the selecteditem is added to LB3 but if I select the same item and click on ADD the items are again added to the LB3.I want to prevent this.Pls respond me ASAP.
I have 2 DataGrid in a single page.

In my markup, in addition to a number of other controls I have the following:
<%:Html.TextBoxFor( m => m.UserName)%>
I'd like to be able to set the focus to this textbox when the page is loaded. Is there a really easy way to do this? I have to admit that so far I haven't found it. I know that I can do this using something like this JQuery/Javascript code: $('#UserName').focus();
However, I don't like the fact that the model field name 'UserName' has to be expressed as a string constant again here - it smells of a maintenance problem. I'd really like to be able to reference the model field directly if possible. Somethiing like this: $('#' + '<%:Html.ModelFieldNameFor(m => m.UserName)%>').focus();
I have wierd situation on my side. I have a page that uses a user control driven by ajax. When I enter a code in txtbox. Corresponding questions for that code are brought into the middle section of page basically in user control. I have requirement of setting the focus on the controls so that I can tabout the field with feel of questions being a part of same page.
I have to manually set the focus for the first question and after going thru all the questions I get control lost. Basically it dont come back to the actual page. I have tried to manually put the focus on the button but I couldnt.
I have a gridview with edit button. I want to set focus on a textbox in a row when clicking "Edit" button. (it is a label before clicking edit, it become a textbox after clicking edit). However, i can't set it focus in Rowdatabound. By the way, I make a simple .aspx page and just put a textbox on the tabcontainer tab panel. I found that i totally cannot set focus on this text box.
Here is aspx page with a text box, the .aspx page code is below:
[code]....
I am trying to set the focus to the user name TextBox which is inside an ASP.NET Login control.
I have tried to do this a couple of ways but none seem to be working. The page is loading but not going to the control.
Here is the code I've tried.
SetFocus(this.loginForm.FindControl("UserName"));
And
TextBox tbox = (TextBox)this.loginForm.FindControl("UserName");
if (tbox != null)
{
tbox.Focus();
} // if
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.
I need to setfocus to a control on a content page from it's master page. I have a master page that contains a TabContainer. Within it's TabPanel is a ContentPlaceHolder. On the content page I have 2 TextBoxes and a Button. I need to set focus to a TextBox on the content page.
The master page:
[Code]....
The master page code behind:
[Code]....
The content page:
[Code]....
I can set the text value of TextBox2 from the master page, but I can't set focus. Can someone give me a clue on how to set focus to TextBox2 on the content page from the masterpage.
In the click event of a listbox, I fill some text boxes and then attempt to .setfocus to one of them.I get error 2110..cant move focus to control..very frustrating, as the texboxes are not .enabled=false, or even.locked=true (which wouldn't keep the focus from moving anyway)the textboxes are unbound
View 2 RepliesI have 4 buttons and 1 FormView.
The FormView has AllowPaging = true.
When you click on a button SQLDataSource1 is bind to the FormView.
So you always have 4 pages.
The data in the FormView has an ID.
When you click Button1 you know you want to see the data with ID=4.
When you click Button2 you know you want to see the data with ID=1.
When you click Button3 you know you want to see the data with ID=2.
When you click Button4 you know you want to see the data with ID=3.
What I want is: when you click on a Button you get the page in the FormView
that corresponds with the ID of the data.
So page 1 isn't ID=1!
What do I have to program to get this working?
Can anyone give me some VB to set focus to a control using the "FindControl" method. MyTextbox.focus() is not good enough because, for instance, I have a textbox called "Username" in the "CreateNewUserWizard" control which is within a Contentplaceholder on a child page so typing in "Username.focus()" does not work on the Page_Load event because Username simply does not have a Focus property.
View 1 Repliesi have used the below gridview item template , which is working fine http://www.aspsnippets.com/Articles/Adding-Dynamic-Rows-in-GridView-with-DropDownLists-in-ASP.Net.aspxI need to set Tab Index here.
1. I have a textbox outside of gridview , on pressing the tab from the textbox in need to focus on gridview item template first row.2.After user click add new button, again i want to focus on the second row on the gridview item template first column.
I have this function:
[Code]....
I set itemsRead and startRowIndex in ViewState:
[Code]....
This is my PageIndexChanged event:
[Code]....
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.
I noticed that with some of the data controls (like gridview and listview) the page loses focus when you click edit, update, etc. So if your data control is somewhere lower on your page, you'd have to scroll down to get to it again. Is this normal or is there a way to keep the focus or location on where you were previously?
