Re: Apply style to div tag. - ASP.NET Discussion Boards

I have a gridview in which a listbox is there. I want to catch the selected change event of the listbox .when the new item is selected i have to replace the data. of the row .

Can anyone help me out .

Find out listbox on RowCreated event of gridview and create selected event of list box.

for Example

OnRowCreated Event

ListBox lstBox=(ListBox)e.Row.FindControl("ListBoxID");
lstBox.SelectedIndexChanged+=(Press Tab 2 times here);

//Now you will get selected index changed event of Listbox
Protected lstBox_SelectedIndexChanged(....)
{
//code here to replace the data of the row
}

Hi all,
i am developing one web site!
in my web page i have one dropdown list for Select language.
how can i change the language for whole content of the pages!
can any body suggest me!

Get all strings from a resource file, and change the file you use, based on the language settng.

can u explain me lilbit detail!

Have a look here.

This gives you a starting point to look into globalization and localization of a asp.net web application.

The main aspects are:
- all language specific things are stored in resources
- the framework chooses automatically the resources that match the current culture settings (Thread.CurrentUICulture and Thread.CurrentCulture)
- all elements in your aspx definition link to an item in a resource file

Thanks for the reply sir, but its not working. I have to actually show this div tag on onmouseover so I am using Ajax HoverMenuExtender which is also created runtime.

The problem is that I am having GridView control which is created runtime and there are 2 Template column and others are BoundField Columns. Template Column is Checkbox and Linkbutton column and on the linkbutton mouseover I have to show the summary.

I dont know where I have going wrong???

Thanks again...

Ok.
tell me where have you used my code?

No I can see the style when I right click view source. The problem is I have to show this div tag only on mouse over div its showing all. here is the code:

I have create a class GridViewTemplate

public class GridViewTemplate: System.Web.UI.Page, ITemplate
{
ListItemType templateType;
string columnName;
private Int32 RowItems;
ArrayList arrgvCompanyName;

public GridViewTemplate(ListItemType type, string colname)
{
templateType = type;
columnName = colname;
}

public GridViewTemplate(ListItemType type, string colname, ArrayList gvCompanyName)
{
templateType = type;
columnName = colname;
arrgvCompanyName = gvCompanyName;
}
public void InstantiateIn(System.Web.UI.Control container)
{
Literal lc = new Literal();
LinkButton lb = new LinkButton();
CheckBox chk = new CheckBox();
TextBox tb1 = new TextBox();
AjaxControlToolkit.HoverMenuExtender hme2 = new AjaxControlToolkit.HoverMenuExtender();
Panel PopupMenu = new Panel();
HtmlGenericControl divtest = new HtmlGenericControl();
HtmlImage imgTop = new HtmlImage();
HtmlImage imgBottom = new HtmlImage();

switch (templateType)
{
case ListItemType.Header:
lc.Text = "<B>" + columnName + "</B>";
if (columnName == "CheckAll")
{
container.Controls.Add(chk);
}
container.Controls.Add(lc);
break;

case ListItemType.Item:
//container.Controls.Add(tb1);
if (columnName == "CheckAll")
{
container.Controls.Add(chk);
}
//else if(columnName="CompanyName")
//{

//}
else
{
if (arrgvCompanyName.Count > 0)
{
columnName = arrgvCompanyName[RowItems].ToString();
lb.Text = columnName;
lb.CommandName = "cmd";

hme2.TargetControlID = "lb";
hme2.PopupControlID = "PopupMenu";
//hme2.PopupPosition = Center;
hme2.OffsetX = 60;
hme2.OffsetY = -15;
hme2.PopDelay = 10;

//Add Top Image For Showing Summary
imgTop.Src = "../../images/top_01.png";
imgTop.Width = 272;
imgTop.Height = 24;

//Add Sytle to div Tag
//divtest.ClientID = "dvtest";
divtest.Attributes.Add("class", "myclass");
divtest.InnerHtml = "My Summary For Testing";
//Add Bottom Image For Showing Summary
imgBottom.Src = "../../images/bottom_01.png";
imgBottom.Width = 247;
imgBottom.Height = 7;

PopupMenu.Controls.Add(imgTop);
PopupMenu.Controls.Add(divtest);
PopupMenu.Controls.Add(imgBottom);

container.Controls.Add(lb);
container.Controls.Add(PopupMenu);
RowItems++;
}
else
{
lb.Text = columnName;
lb.CommandName = "cmd";
container.Controls.Add(lb);
}
}
//container.Controls.Add(chk);
break;
}
}
}

and from code behind I am calling this as:

foreach (DataColumn objDC in myTable.Columns)
{
if (objDC.ColumnName == "CheckAll")
{
TemplateField chkColumn = new TemplateField();

chkColumn.HeaderTemplate = new GridViewTemplate(ListItemType.Header, "CheckAll");

for (int j = 0; j <= myTable.Rows.Count - 1; j++)
{
chkColumn.ItemTemplate = new GridViewTemplate(ListItemType.Item, "CheckAll");
}

gvWatchList.Columns.Add(chkColumn);
}
else if (objDC.ColumnName == "CompanyName")
{
TemplateField linkbtnColumn = new TemplateField();

linkbtnColumn.HeaderTemplate = new GridViewTemplate(ListItemType.Header, "CompanyName");

//linkbtnColumn.ItemTemplate = new GridViewTemplate(ListItemType.Item, myTable.Rows[iCompCount][1].ToString());
ArrayList score = new ArrayList(myTable.Rows.Count);
for (int j = 0; j <= myTable.Rows.Count - 1; j++)
{
score.Add(myTable.Rows[j][1].ToString());
//gvWatchList.Rows[j].Cells.Add(tt);
}

//linkbtnColumn.ItemTemplate = new GridViewTemplate(ListItemType.Item, score.ToString());
linkbtnColumn.ItemTemplate = new GridViewTemplate(ListItemType.Item, "", score);
GridViewTemplate temp = new GridViewTemplate();
temp.RowItem = score.Count;
gvWatchList.Columns.Add(linkbtnColumn);

}
else
{
BoundField bField = new BoundField();
bField.DataField = objDC.ColumnName;
bField.HeaderText = objDC.ColumnName;
gvWatchList.Columns.Add(bField);
}
}
gvWatchList.RowStyle.CssClass = "GridRowColor";
gvWatchList.HeaderStyle.CssClass = "GridHeader";
gvWatchList.AlternatingRowStyle.CssClass = "GridAlternateRowColor";
gvWatchList.CssClass = "grid-text";
gvWatchList.DataSource = myTable;
gvWatchList.DataBind();
}

this is wat I am using in User Control.

Thanks again...

If you are adding styles I would suggest using a CSS class rather than explicity adding it in code, it makes it more managable and reusable

divtest.attributes.add("class", "myclass")

and then define in a CSS file myclass with the attributes you want

div.myclass
{
text-align: right;
display: none;
overflow: auto;
scrollbar-face-color : #ffffff;
scrollbar-highlight-color : #000000;
scrollbar-3dlight-color : #cccccc;
scrollbar-shadow-color : #000000;
scrollbar-darkshadow-color : #cccccc;
scrollbar-track-color : #cccccc;
scrollbar-arrow-color : #000000;
}

It also means you dont have to recompile if you need to make changes.

However, if you do need to apply it directly in code for some reason then i would suggest using the built in style property which can be strongly typed which is always nice, as follows

divtest.Style.Add(HtmlTextWriterStyle.TextAlign, "right")

or for ones which are not included in the strongly typed list use

divtest.Style.Add("scrollbar-face-color", "#000000")

Hope that helps

Both sets of code provided as answers will work, and are valid ways of doing it, but you seem to have a specific implementation issue here.

Can you please just let me know what the issue is that you are having - does the div show? Is it just missing the style information?

No I can see the style when I right click view source. The problem is I have to show this div tag only on mouse over div its showing all. here is the code:

From looking at the code the obvious is that you are not setting the ID property of the panel which you want to show, you are setting TargetPopupId to be 'PopupMenu' but that is the name of the object, not the Id of the control which you want to use, try adding the line

PopupMenu.Id = "PopupMenu"

It is not the div which you are trying to hide or display on the mouseover but the panel also, the div is just a control within the panel.

Really you should set the Id property for all controls you add on the page, especially if they are containers. Also im not sure what the default is but you should perhaps specifty the type of generic html control in the constuctor

HtmlGenericControl divtest = new HtmlGenericControl("Div");

Thanks for the reply sir but I have tried that also, but its not working... Frown | :(
