In a WebForm I have
TextBox
FreeTextBox(Third party tool)
CheckBox
I gave tab index value for TextBox as 1 and CheckBox as 2 by setting TextBox to default focus. The Problem is after the page is loaded when I press tab, insted of moving focus to checkbox, URL bar of the browser is getting focused.
I have a CascadingDropDown on an ASP.NET page. Now, the prompt text is "Select State". (list of states). However, on a different version of this page (ie querystring), i might want to set the selected index to "California" for example. How can i do this? The web service used by the ajax control (ie GetStates) gets invoked at the same time the jquery document.ready function is triggered (ie asynchronously).
So when i try and set the selected index in jquery, the items are not yet bound. Is there a way to attach a handler to the ajax dropdown so that i can set the selected index once the webservice call has completed, and the items are bound?
I have looked high and low and have not found what I need or found something that could work but it was old and did not work. I have a datalist (in an update panel) that contains 2 dropdownlist (Categories and Sub Categories) being populated by CascadingDropDown. What I want to do is set the selected index of the First one to the value I get from the Database after populating it in the web service. Then based on that I would like to adjust the 2nd dropdown for the new selected index. Here is the ui code
[Code]....
I saw a post about CascadingDropDownProperties using Atlas but I cannot seem to find anything about the AtlasControlKit anymore (is it part of AjaxControlKit?)
I 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.
Why I am unable to setfocus to my list box if the index > 820

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...

View 2 RepliesI'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.
These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.

Error i am facing is :

Cannot create the clustered index 'RateViewIndex' on view 'NoteToPass.dbo.RateView' because the select list of the view contains an expression on result of aggregate function or grouping column. Consider removing expression on result of aggregate function or grouping column from select list.
what is difference in cluster index and noncluster index?
which is faster?how many cluster index and non cluster index per table?
what is composite primary key?on how many columns we can create composite key?
hao many maximum composite key's we can create on one table?
I have two control page in my aspx page. first one left side "tree view",second one right side " form design".Form design will change based on tree view selected index changed.i have 4 level child node(site, master , slave, space). I have seperate forms to each level of node.
cannot update tree node when update the forms. so i reload tree view.
now i need how to auto selected index change to tree node.
ex.
1 parent node
1.1 child node
1.2 child node
i have update "1.2 child node" rename to "1.3 child node"
and reload treeview so it will chage...
how set tree node.selected index = 1.3 child node....
gvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.
I have develop a web application. I have put my web application in my server and user can access from any location.
My server regional and setting is English (US). Now my problem is
1) When user access to my system and his pc setting is English (UK), it will prompt and error
and after i debug i suspect it is because of Datetime conflict (dd/MM/yyyy and MM/dd/yyyy)
2) I cannot fix or limit my user to setting his/her pc regional setting to UK
So what can i do in my web application solve this issue?
(Can i write any code in my client side (.aspx) to convert or do standardization to US)
I would like to set a value:

...where [HERE] is the placeholder for my value, from my code behind in ASP.NET before the page is rendered. I generate a guid, and I need that apart of the script on the page.

View 8 RepliesI'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?

View 4 RepliesI have an ASP.NET MVC app and I have a WebForm page I built in the MVC due to a tutorial on how to do something I needed to do, but it was all in WebForm style. Ive tried to figure out how to do the same thing in MVC format but cant figure it out. So I was needing to figure out how to use this page in my MVC app. But when I try to go to the page, it gives me the error "Page cannot be derived from ViewMasterPage unless Page derives from ViewPage." So I had to make a new standard MasterPage also.
The situation is this. I have a search bar located in the MVC ViewMasterPage thats on every page that is derived from it. Once a user submits info in the search bar, it calls the WebForm Search.aspx page and displays the results on the Search.aspx page. I want the URL to be like "http:///search//. The Search.aspx page is located in the root of the project. How would I get the results Im looking for?
