UltraWebGrid使用总结1--足够你日常所用~~

1.新增一行

gvForm.DisplayLayout.Rows.Add();

2.绑定dropdownlist/textbox到webgrid中，并将数据库中的值赋给它

TemplatedColumn source = (TemplatedColumn)gvForm.Bands[0].Columns[3];

foreach (CellItem item in source.CellItems)

{

string source1 = gvForm.Rows
.Cells.FromKey("SOURCE").Text;

DropDownList r = (DropDownList)item.FindControl("ddlsource");

//r.Items.Add(new ListItem(source1, source1));

r.Items.FindByValue(source1).Selected = true;//下拉框將值選中顯示

n++;

}

3.某个cell可编辑：

gvForm.Rows[0].Cells[1].AllowEditing = AllowEditing.Yes;//UNIT_PRICE

4.某个column可更新

gvForm.Columns.FromKey("upb").AllowUpdate = AllowUpdate.Yes;

5. 获取某行行号及Itemcommand 内容写法：

protected void gvForm_ItemCommand(object sender, UltraWebGridCommandEventArgs e)

{//delete

ImageButton image = (ImageButton)e.CommandSource;

int id = int.Parse(image.CommandArgument);

switch (image.CommandName)

{

case "D":

Bind(hlineid.Value);

break;

}

}

6.某列放dropdownlist ddl，选中值后触发SelectedIndexChanged事件使其他列绑定值：需要将该ddl 属性设置为：autopostback=true,

方法如下：

protected void Drpd_SelectedIndexChanged(object sender, EventArgs e)

{

　　 DropDownList ddltrx=sender as DropDownList;

int row=((CellItem)ddltrx.NamingContainer).Cell.Row.Index;//获取该行行号

.......

｝

7.使grid中的某列隱藏

gvForm.Bands[0].Columns[0].Hidden = true;

8.設置grid中某列背景及字體顏色

gvForm.Rows[i].Cells[0].Style.ForeColor = System.Drawing.Color.White;

gvForm.Rows[i].Cells[0].Style.BackColor = System.Drawing.Color.CornflowerBlue;
