Re: perform custom paging in gridview on a button click

I don't believe the gridview suports that, you'd have to write your own paging control.

Custom Paging in GridView

Hello Friends,

I'm implementing custom paging in my GridView. Paging numbering(in-built paging numbering) does not display but it brings the records are queried . Below giving my code please let me know what changes i should make in my code. But if i use in-built paging(normal paging) then that's working fine......

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
lblMsg.Text = e.NewPageIndex.ToString();
int pageNumber=Convert.ToInt32(e.NewPageIndex);
int recordPerPage= 4;
int startRecord = (pageNumber) * recordPerPage + 1;
int maxRecord = startRecord + recordPerPage;

bindGridView1(startRecord,maxRecord);
}

public void bindGridView1(int startRecord,int maxRecord)
{
string connectionString = "server=.;database=Auto_New;uid=sa;pwd=;";

using(SqlConnection mCon = new SqlConnection(connectionString))
{
SqlCommand mDataCom = new SqlCommand();

mDataCom.Connection = mCon;

mDataCom.CommandType = CommandType.StoredProcedure;
mDataCom.CommandText = "SP_Select1";
mDataCom.Parameters.AddWithValue("@startRecord", startRecord);
mDataCom.Parameters.AddWithValue("@maxRecord", maxRecord);

SqlDataAdapter da = new SqlDataAdapter(mDataCom);
DataSet ds = new DataSet();
da.Fill(ds);

GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
}
}

fixed headers

Hi All,

I have a table with headers as below, table displyed with a horizontal and vertical scroll bars within DIV tag. When it is displayed in IE browser headers width is normal but when they are displayed in Mozilla or Safari browsers they are displayed with reduced column widths when compared with its items below.
I found the reason for this is below code(overflow: ovfl), but when I put the overflow: auto here the header widths are proper but when we scroll vertical bar headers are going inside of the DIV tag.

if(DIV_Array.clientHeight&gt;290){$(TAB_Array).fixedHeader({width: 900,height: h, overflow: ovfl});}

Can anybody give me advice to make the headers fixed and their widths are also fixed according to the width of columns.

Thanks in advance.

This is the table header part

<th class="RowHeader2Cell1" align="left" style="white-space:nowrap;width:20%;">Asset Name</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">CUSIP</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">ISIN</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">SEDOL</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Ticker</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Current Allocation</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Quantity</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Current Price</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Date Priced</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Market Value</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Total Cost</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Unrealized Gain/Loss</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Estimated Annual Income</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Yield</th>
                <th class="RowHeader2" align="right" style="white-space:nowrap;width:20%;">Portfolio</th>

Hi dear try this...

How to Freeze GridView Header While Scrolling ?
This is very common problem in Web development that we need to freeze the GridView header at the time of scrolling, Here is one simple tips:
Step 1 : Create a CSS class as following
view plaincopy to clipboardprint?
1. .HeaderFreez
2. {
3. position:relative ;
4. top:expression(this.offsetParent.scrollTop);
5. z-index: 10;
6. }
Step 2 Set Gridview’s HeaderStyle CssClass as follows
CssClass="HeaderFreez"
That’s all. Some times we need also maintain the scroll positions while selecting any data from GridView, and quite difficult to maintain the position while we are using AJAX, I have written a complete article on that, hope this will help Maintain GridView Scroll Position inside updatepanel

Hi,

I am able to create the scroll bars but my problem is the headers widths are differing with column widths. The header widths are decreasing where as the column widths are remaining same.

This problem is coming only in Mozilla browsers. But if I say overflow:auto for its properties its header widths are good, but header is becoming invisible when I scroll down.

Thanks,
Md Abdul Aleem.

Hi,

It was working fine until I drag the vertical scroll bar down, but when I scroll it down again its header widths are changing.
As that part belongs to the following CSS, can you please suggest me what change should I do to make the headers freezed even if vertical scroll bar is dragged.

.HeaderFreez 
{ 
position:relative ; 
top:expression(this.offsetParent.scrollTop); 
z-index: 10; 
}

Thanks in advance,
Md Abdul Aleem.

Reg: cache concept

can someone explain if i need to use all the three lines of code mentioned below to disable the cache in a page.actually if i am using only Response.CacheControl = "no-cache" then also page is working properly.then what is the use of another two line..and also is it a server side cache or client side?

Response.CacheControl = "no-cache"
Response.AddHeader("Pragma", "no-cache")
Response.Expires = -1

I think for client cache only Response.Expires will do. No need for those cache headers.

Your best bet is to change the image before sending it to the client, but I believe a rounded rectangle effect can be created with css. I am not sure how, you'd have to google it.

Hello.

I finished a bullentin board with Repeater on my pages .

I would like to make a seaching box(?) to show up a result on the list of Repeater, when someone searchs something by inputting on textbox.

So, I put Dropdownlist, Textbox and imagebutton through tool box on the page.

I mean I would like to make something like "Search" on top of this page.

Search [ Text Box ] [Dropdownlist] [button]

And I'm coding like the following code.

protected void Select_Btn1_Click(object sender, ImageClickEventArgs e)
{

string title;

title = Search_Txt1.Text;
if (DropDownList1.SelectedValue== "Title")
{

SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["aspnetdbConnectionString"].ConnectionString);
string sql = "Select * From t_Pds where Title = '"+ Title +"' ";

}
}

But I don't know how to show up the result on the list of Repeater.

Re: I'm making a bulletin board.

28-Jul-09 21:38

Well, you have bigger issues than that. The obvious solution to your immediate problem ( apart from the general poor coding style ), is to run your SQL and bind your repeater to the result. Your bigger issue, is that I can erase your bullitin board simply by typing in the right search term. Do some research on SQL injection attacks.

Hey,
Just you can do like this :

SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["aspnetdbConnectionString"].ConnectionString);
string sql = "Select * From t_Pds where Title = @p_search ";
SqlCommand cmd = new SqlCommand(sql,cn);
cmd.Parameters.add("@p_search",SqlDbType.VarChar,100);
SqlDataAdapter sAdpt = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
sAdpt.Fill(ds, "t_Pds");

Now you bind the sql to the Repeater:

yourrepeater.DataSource = ds.Tables["t_Pds"];
yourrepeater.DataBind();

The music player is probably going to cache it internally, but I guess it depends on which player you use.
