I have a GridView which has DataKey[0] as productId. If i have for instance productId = 54, is there any way to search through all GridView item and set as selected the one who has DataKEy[0] = 54?
For a drop down list i have :
ddlProducts.Items.FindByValue(lblProduct.Text.ToString())).Selected = true
Is anything similar for GridView?
I am referring this article :

now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) {
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(document).ready(function () {
$('.search_textbox').each(function (i) {
[Code] .....
Here's my code structure for gridview :
<asp:UpdatePanel ID="ConstructionActPhaseUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:gridview ID="PhasesTempGrid" ClientIDMode="Static" OnDataBound="PhasesTempGrid_OnDataBound" allowpaging="True" OnPageIndexChanging="PhasesTempGrid_OnPageIndexChanging"
[code]...
and the way i bind the data to gridview is from textboxes ....

View 5 Replies I have Gridview1 that brings up the columns Resorts, Seasons, Seasons_ID, Resorts_ID, and User_ID
The three ID's are all foreign keys from related tables, and they are together a combined primary key of the table being accessed (they were defined that way to prevent duplicate entries for any User/Resort/Season combination).
Now the problem: I want to use the selected row from that gridview in the WHERE clause of a SQLDatasource by setting the WHERE clause up like:
WHERE (([Resort_ID] = @Resort_ID) AND ([Season_ID] = @Season_ID) AND ([User_ID] = @User_ID)) , with the parameters each coming from statements like
Gridview1.SelectedValue
When I select a row in the Gridview, I get the following error:
Operand type clash: uniqueidentifier is incompatible with int
I am pretty sure this has to do with the User_ID being in the WHERE clause.
So I have tried something like this to access the selected index:
Gridview1.DataKeys(Gridview1.SelectedIndex).Value
This does not work, as it seems to return only the first key (of three) in the DataKeyNames list.
So the question: How can I use the SelectedIndex of that gridview for such a purpose when the key contains a UserID?
In ASP.NET, I can get the selected index of dropdownlist using:
var dropdown1 = document.getElementById('dropdown1');But I want the selected index of that dropdownlist, which is present INSIDE a GridView.How to get that using JavaScript?

I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005. I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this. But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.
the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.

For Edit I want to select the OfficeName before Selecting a Department or any another way to do this
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.
