and in coding part(c#) i written like;
void dgUserNote_UpdateCommand(object source, DataGridCommandEventArgs e)
{
SqlCommand SqlCom;
if (ConGlobal.State == ConnectionState.Closed) ConGlobal.Open();
SqlCom = new SqlCommand("SpInsertUserNote", ConGlobal);
SqlCom.Parameters.Add("@IorU", SqlDbType.VarChar).SqlValue = "U";
SqlCom.Parameters.Add("@Title", SqlDbType.VarChar).SqlValue = e.Item.Cells[2].Text;
SqlCom.Parameters.Add("@Description", SqlDbType.VarChar).SqlValue = e.Item.Cells[3].Text;
SqlCom.Parameters.Add("@Date", SqlDbType.VarChar).SqlValue = e.Item.Cells[4].Text;
SqlCom.Parameters.Add("@UserName", SqlDbType.VarChar).SqlValue = mdlNewClass.gStrUserName;
SqlCom.CommandType = CommandType.StoredProcedure;

First you need to set the EditItemIndex property to the index of the item clicked in the DataGrid control to enable editing for that item.
void dgUserNote_Edit(Object sender, DataGridCommandEventArgs e)
{
dgUserNote.EditItemIndex = e.Item.ItemIndex;
BindUserNoteGrid();
}
If you have used bound columns, the edited value is stored in a TextBox in the Update event.
The TextBox is the 0th control in a cell's Controls collection.
Each cell in the Cells collection of a DataGrid item representsa column in the DataGrid control.
Change your code like below and then use the TextBox values in SQL Parameters.
TextBox titleText = (TextBox)e.Item.Cells[2].Controls[0];
TextBox descriptionText = (TextBox)e.Item.Cells[3].Controls[0];

hi
i have code at grid view editing have proble at update time
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//fetch datakey/primarykey for identifyning the row
string materialrecipt_no = Convert.ToString(GridView1.DataKeys[e.RowIndex].Value);
TextBox materialrecip_date = (TextBox)GridView1.Rows[e.RowIndex].Cells[2].Controls[1];
TextBox pqty = ((TextBox)GridView1.Rows[e.RowIndex].Cells[3].Controls[1]);
TextBox enterby = ((TextBox)GridView1.Rows[e.RowIndex].Cells[4].Controls[1]);
TextBox ptype = ((TextBox)GridView1.Rows[e.RowIndex].Cells[5].Controls[1]);
TextBox remark = ((TextBox)GridView1.Rows[e.RowIndex].Cells[6].Controls[1]);
SqlCommand com = new SqlCommand("update material_incoming set materialrecip_date='" + materialrecip_date.Text + "',pqty='" + pqty.Text + "',enterby='" + enterby.Text + "',ptype='" + ptype.Text + "',remark='" + remark.Text + "' where materialrecipt_no=" + materialrecipt_no + "", conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
GridView1.EditIndex = -1;
//to go back to the previous position
// fetch and rebind the data.
BindGrid();
}
but it gives an error
error is
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
|
|
|
|
|
Set a break point in your code, Find which line of code throws the error
check the following
e.RowIndex - if it is a negative value, it may throw an error at GridView1.Rows[e.RowIndex]
Cells collection - check whether indexs of the grid cells are within the range.

Hi,
What i think the problem is in the place where you refer to your control using Cells[index].Controls[1] and there would have been only one control and that too at position [0] not [1]. So try using the code like this as you do know the name of the control which you want to fetch using the code for updation purpose.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//fetch datakey/primarykey for identifyning the row
string materialrecipt_no = Convert.ToString(GridView1.DataKeys[e.RowIndex].Value);
TextBox materialrecip_date = (TextBox)GridView1.Rows[e.RowIndex].FindControl("ControlName");
TextBox pqty = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("ControlName"));
TextBox enterby = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("ControlName"));
TextBox ptype = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("ControlName"));
TextBox remark = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("ControlName"));
SqlCommand com = new SqlCommand("update material_incoming set materialrecip_date='" + materialrecip_date.Text + "',pqty='" + pqty.Text + "',enterby='" + enterby.Text + "',ptype='" + ptype.Text + "',remark='" + remark.Text + "' where materialrecipt_no=" + materialrecipt_no + "", conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
GridView1.EditIndex = -1;
//to go back to the previous position
// fetch and rebind the data.
BindGrid();
}
Please mark as answer if problem gets resolved.

Just deploy with clickonce and it will work by itself. If you want to write something, then you just need a program to contact a server with a version number, and the server to send a higher version if it exists.

First no array is declared in your code.
Fill the array in the first Panel and store it in Session object, and then load it in the second panel.

Hi,
I am Encoding my Url like :
Response.Redirect("~/Default.aspx?"+Server.UrlEncode(("I1=18&I2=1&I3=506")));
It is working Fine,But When i tried to Decode the Url like :
Server.UrlDecode(Request.QueryString.ToString());
It is not working as expected , It is returning the Count of Query String as 1,But i expect it as 3,
Plz help me how to Decode the Querystring ?
Thanx in Advance!!!!
|
|
|
|
|
there r several predefined algorithm in .net security package which can be used dirctly to encode &decode the url............ok
|
|
|
|
|
i used the Server.EncodeUrl() method , i am talking based on this.
|
|
|
|

You should not encode the whole string "I1=18&I2=1&I3=506".
Since you are encoding the three query strings I1=18&I2=1&I3=506 into one, it is loaded as a single query string in the target page.
To avoid this, Encode querystring parameter I1 and the value 18 separately and join using '=' operator.
Repeat this for next paramters and theri values and join with the previous set using '&'.
It should be like below
Response.Redirect("~/Default.aspx?"+ "encodeedI1=encoded18& encodedI2= encoded1& encdoedI3=encoded506";
Then only you can get three Query Strings in the Default.aspx.

I can't follow this waffle, but URL rewriting is easy, just write your own class to do it. Sounds like you're using other classes - why ?

Hi,
I am developing a web app. and i have given a provision to upload images for the users of various categories, So i want to know if :
> storing images of various categories in a single folder is good rather than storing images in separate folders of different categories?
> Does these methods have performance variation , while fetching the url's during displaying the data?
Plz help

It plainly makes no difference to performance, but it could make a difference if filenames clash.

How can I change password by email and new password?

|
|

How do you think ? How do other sites do it ?
You store a key which is passed in on the URL sent to the email address given, which then validates that they got the email.
